TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
1 GENERAL DESCRIPTION
1.1 Basic functionality
TCM 515B provides radio transceiver functionality (telegram transmission and reception)
according to the Bluetooth Low Energy standard in the 2.4 GHz radio band. TCM 515B receives and transmits radio telegrams based on a whip or PCB antenna connected via the
host PCB.
TCM 515B is primarily intended for use within energy harvesting wireless sensors where it
will provide the required radio functionality. To meet this requirement, TCM 515B provides
a radio application programming interface (API) for transmission and reception of 2.4 GHz
BLE radio telegrams. This radio API can be used by sensor applications running on TCM
515B to transmit and receive radio telegrams.
Additionally, TCM 515B provides an ESP3 interface to an external host which can be used to
transmit and receive data tele-grams.
TCM 515B provides an I2C interface which can be used to connect external sensors.
TCM 515B is implemented as 31 pin reflow-solderable module in an optimized form factor
to enable size constrained applications. The module design is mechanically compatible with
the other members of the TCM 515 radio transceiver family to enable reuse.

TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
2.1.1 Signal Description
TCM 515B is supplied by the VDD and GND Pins. The required supply voltage is 3.3V with a
tolerance of no more than +-10%.
TCM 515B receives and transmits data based on a 50Ω whip antenna connected to its ANTENNA input (Pin 2).
TCM 515B communicates with the external host using the standard ESP3 serial (UART) interface based on the signals UART_TX (Pin 21, direction from TCM 515B to external host)
and UART_RX (Pin 20, direction from external host to TCM 51Z).
The default interface speed of the ESP3 interface is 57600 bit per second (the exact speed
is 57347 Bit per second, a deviation of -0.04%).
It is possible to select faster communication speeds of 115200, 230400 and 460800 bit per
second during operation using the ESP3 CO_SET_BAUDRATE command.
Additionally it is possible to change the default ESP3 interface speed at power up from
57.600 Bit per second to 460.800 Bit per second by connecting the TURBO input (Pin 31) to
Ground. Subsequent modification of the interface speed during operation using the
CO_SET_BAUDRATE command is always possible irrespective of the state of the TURBO
input pin.
TCM 515B provides one or two I2C interfaces as primarily means to connect external sensors. Additionally, it provides digital and analog inputs and outputs as well as the option for
an SPI interface.
2.2 High-level operation principle
In receive mode, TCM 515B forwards the content of received BLE radio telegrams (which
pass frame check sum validation) unmodified to the sensor application SW or an external
host via the ESP3 interface. The sensor application can use the data of received telegrams
for instance to adjust parameters such as update intervals.
In transmit mode, TCM 515B receives from the application SW or an external host the precomputed message payload. TCM 515B then calculates the frame check sum and appends it
to the message. The full frame (including the Preamble and Start of Frame fields) will then
be transmitted as BLE radio telegram (TX mode).
The sensor application uses an internal or external timer to periodically wake-up and check
the status of the connected sensors. Based on this status information, it will decide if
transmission of a telegram is necessary and if so forward it to the radio routine by means
of its API.
TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
2.3 Radio functionality
TCM 515B transmits and receives advertising telegrams within the 2.4 GHz radio frequency
band (2402MHz … 2480MHz) using the BLE advertising frame format.
By default, TCM 515B will use the three BLE advertising channels (BLE Channel 37, 38 and
39) defined for transmission and reception. The transmission of a radio telegram on these
three advertising channels is called an Advertising Event.
Use of different radio channels within the frequency band from 2402 MHz to 2480 MHz is
possible and can be configured by the application software or the external host (via ESP3
interface).
Table 2 below summarizes radio channels supported by TCM 515B.

TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
2.4 Radio transmission sequence
TCM 515B transmits telegrams in its standard configuration by using so-called Advertising
Events.
An advertising event is defined as the transmission of the same radio telegram on all selected radio channels (by default this would be on BLE Channel 37, 38 and 39) one after
another with minimum delay in between.
For reliability reasons, TCM 515B will send three redundant advertising events for each
transmission. The resulting transmission sequence is shown in Figure 3 below.
Figure 3 – Default radio transmission sequence
2.5 Radio reception sequence
TCM 515B receives radio telegrams in its standard configuration by monitoring the Advertising Channels (Channel 37, 38 and 39). Alternative channels can be selected via the radio
API or the ESP3 interface.
TCM 515B will continuously scan these channels one after the other for valid data telegrams. The time spent on each channel is configurable.
2.6 User-defined radio channels
In certain situations it might be desirable to transmit and receive radio telegrams on channels other than the three advertising channels.
TCM 515B therefore allows to select the radio channels to be used for the transmission and
reception. The selection of the radio channels is done by the application SW using the radio
API or the external host using the ESP3 interface.
TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
3 Telegram format
TCM 515B transmits and receives radio telegrams in the 2.4 GHz band according to BLE
frame structure. For detailed information about the BLE standard, please refer to the applicable specifications.
Figure 4 below summarizes the BLE frame structure.
Figure 4 – BLE frame structure
The content of these fields is described in more detail below.
3.1 Preamble
The BLE Preamble is 1 byte long and identifies the start of the BLE frame. The value of the
BLE Preamble is always set to 0xAA.
3.2 Access Address
The 4 byte BLE Access Address identifies the radio telegram type. For advertising frames,
the value of the Access Address is always set to 0x8E89BED6.
3.3 Header
The BLE Header identifies certain radio telegram parameters. Figure 5 below shows the
structure of the BLE header.
TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
3.4 Source address
The 6 byte BLE Source Address (MAC address) uniquely identifies each TCM 515B product.
TCM 515B supports two source address modes:
Static Source Address mode (default)
In this mode, the source address is constant (but its lower 32 bit can be configured
via radio API)
Private Resolvable Address mode (NFC configurable)
In this mode, the source address changes for each transmission
TCM 515B uses by default the Static Source Address mode. Private Resolvable Address
mode can be selected via the radio API. These two address modes are described in the following chapters.
3.4.1 Static source address mode
By default, TCM 515B uses static source addresses meaning that the source address is constant during normal operation. The structure of TCM 515B static addresses is as follows:
The upper 2 bytes of the source address are used to identify the device type and set
to 0xE500 to designate EnOcean STM 500 multi-sensor type. These two bytes cannot
be changed.
The lower 4 bytes are uniquely assigned to each device.
Figure 6 below illustrates the static address structure used by TCM 515B.
TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
3.4.2 Private resolvable source address mode
For some applications it is desirable to modify (rotate) the source address used by TCM
515B in order to prevent tracking of its radio transmissions. At the same time, each TCM
515B device must remain uniquely identifiable by the receiver.
To achieve these goals, TCM 515B can be configured via radio API to use random resolvable
private addresses.
Using random resolvable private addresses requires that both TCM 515B and the receiver
both know a common key – the so-called Identity Resolution Key (IRK). TCM 515B uses its
device-unique random key as identity resolution key.
For resolvable private addresses, the 48 bit address field is split into two sub-fields:
prand
This field contains a random number which always starts (two most significant bits)
with 0b10. The prand value is changed for each telegram that is transmitted. Individual advertising events used to transmit one telegram use the same prand value.
hash
This field contains a verification value (hash) generated from prand using the IRK
The structure of a random resolvable private address is shown in Figure 7 below.
Figure 7 – BLE private resolvable source address structure
The prand value is encrypted using the IRK. The lowest 24 bit of the result (encrypted
value) are then used as hash.
The concatenation of 24 bit prand and 24 bit hash will be transmitted as 48 bit private resolvable source address.
TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
The receiving device maintains a list of IRK for all transmitters that have been commissioned to work with it.
Whenever the receiving device receives a radio telegram with private resolvable source
address (identified by the most significant bits being set to 0b10), it will itself generate a 24
bit hash from the 24 bit prand sequentially using the IRK of each device that it has been
learned into it.
If an IRK matches (i.e. when prand is encoded with this specific IRK then the result
matches hash), then the receiver has established the identity of the transmitter.
So conceptually the IRK takes the role of the device source address while prand and hash
provide a mechanism to select the correct IRK among a set of IRK.
This mechanism is illustrated in Figure 8 below.
Figure 8 – Resolving private source addresses
3.5 Check Sum
The 3 byte BLE Check Sum is used to verify data integrity of received BLE radio telegrams.
It is calculated as CRC (cyclic redundancy check) of the BLE Header, Source Address and
Payload fields.
TCM 515B will discard received radio telegrams that do not pass the CRC check.
TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
3.6 Payload
The payload of data telegrams is up to 31 bytes long (depending on the size of the sensor
data) and consists of the following fields:
Length (1 byte)
The Length field specifies the combined length of the following fields and depends on
the size of the Sensor Status field. The minimum length is 13 byte and the maximum length is 31 byte
Type (1 byte)
The Type field identifies the data type used for this telegram. For TCM 515B data
telegrams, this field is always set to 0xFF to designate manufacturer-specific data
field
Manufacturer ID (2 byte)
The Manufacturer ID field is used to identify the manufacturer of BLE devices based
on assigned numbers. EnOcean has been assigned 0x03DA as manufacturer ID code.
Sequence Counter (4 byte)
The Sequence Counter is a continuously incrementing counter used for security
processing. It is initialized to 0 at the time of production and incremented for each
telegram (data telegram or commissioning telegram) sent.
Sensor Data (variable size)
The Sensor Data field reports the measured values of the sensors. The encoding of
this field is described in chapter 3.7.
Security Signature (4 byte)
The Security Signature is used to authenticate TCM 515B radio telegrams as described in chapter 0
Figure 9 below illustrates the telegram payload structure.
TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
3.7 Sensor status encoding
The Sensor Status field within the Payload data identifies the status of the connected sensors. The Sensor Status field is composed of sub-fields (one per sensor attribute).
Each sub-field consists of two items:
Sensor Data Descriptor
The descriptor identifies the type of the attribute and the size of the following data
field
Sensor Data
The sensor data encodes the attribute data
Figure 10 below shows the structure of the sensor status field.
Figure 10 – Sensor Status field structure
3.7.1 Sensor Data Descriptor
The Sensor Data Descriptor describes type and size of the following sensor data field. It
explicitly specifies the size to ensure forward compatibility, i.e. to enable future receivers to
parse sensor telegrams containing unknown data types.
The Sensor Data Descriptor structure is shown in Figure 11 below.

3.7.2 Sensor Status
The Sensor Status field encodes the current status (last reported value) of a sensor.
As described above, the type of the sensor data is identified by the Data Type ID field and
its size is identified by the Data Size field of the preceding Sensor Data Descriptor.
Table 3 below shows the sensor status encoding used by TCM 515B.
TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
3.8 TCM 515B telegram authentication
TCM 515B implements telegram authentication to ensure that only telegrams from senders
using a previously exchanged security key will be accepted. Authentication relies on a 32
bit telegram signature which is calculated as shown in Figure 12 below and exchanged as
part of the radio telegram.
Figure 12 – Telegram authentication flow
Sequence counter, source address and the remaining telegram data together form the input data for the signature algorithm. This algorithm uses AES128 encryption based on the
device-unique random security key to generate a 32 bit signature which will be transmitted
as part of the radio telegram.
The signature is therefore dependent both on the current value of the sequence counter,
the device source address and the telegram payload. Changing any of these three parameters will therefore result in a different signature.
The receiver performs the same signature calculation based on sequence counter, source
address and the remaining telegram data of the received telegram using the security key it
received from TCM 515B during commissioning.
The receiver then compares the signature reported as part of the telegram with the signature it has calculated. If these two signatures match then the following statements are
true:
Sender (TCM 515B) and receiver use the same security key
The message content (address, sequence counter, data) has not been modified
At this point, the receiver has validated that the message originates from a trusted sender
(as identified by its security key) and that its content is valid.
In order to avoid message replay (capture and retransmission of a valid message), it is
required that the receiver tracks the value of the sequence counter used by TCM 515B and
only accepts messages with higher sequence counter values (i.e. not accepts equal or lower
sequence counter values for subsequent telegrams).
TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
3.9 ESP3 Interface
TCM 515B provides a bi-directional UART interface for communicating with the external
host. The default baud rate of this interface is 57600 bps. If the TURBO pin is set to active
low then the baud rate is increased to 460.800 bps.
3.9.1 ESP3 Data Format
TCM 515B communicate with external hosts using EnOcean Serial Protocol version 3 (ESP3)
with EnOcean 2.4 GHz extensions.

4.3 Soldering information
TCM 515B has to be soldered according to IPC/JEDEC J-STD-020C standard as outlined in
Figure 23below.
Figure23–Recommendedtemperatureprofile
4.4 Device handling instructions
TCM 515B shall be handled according to Moisture Sensitivity Level MSL 3. TCM 515B may
be soldered only once, since one time is already consumed at production of the module
itself.
Once the dry pack bag is opened, the desired quantity of units should be removed and the
bag resealed within two hours. If the bag is left open longer than 30 minutes the desiccant
should be replaced with dry desiccant. If devices have exceeded the specified floor life time
of 168 h, they may be baked according IPC/JEDEC J-STD-033B at max. 90 °C for less than
60 h.
Devices packaged in moisture-proof packaging should be stored in ambient conditions not
exceeding temperatures of 40 °C or humidity levels of 90% r.H.
TCM 515B modules have to be soldered within 6 months after delivery!
TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
In general we recommend a no clean flux process. If washing is needed, then TCM 515B
radio modules have a shield cover with small openings at the top of the edges.
It is very important to mount the modules in a top down position during the drying process
as this will allow getting the aggregated washing fluid removed properly from within the
shield cover area.
To prevent damage, modules have to be checked for any remaining fluid after the drying.
4.5 Device operation instructions
TCM 515B shall only be operated while assembled onto a PCB that is integrated into a suitable product housing.
TCM 515B shall only be supplied using “Limited Power Sources” compliant with EN 62368-1
clause 6.2.2.4 and a maximum output power of 15W (PS1).
TCM 515B – 2.4 GHZ BLUETOOTH LOW ENERGY (BLE) Transceiver
5 APPLICATION INFORMATION
5.1 Transmission range
The main factors that influence the system transmission range are:
- Type and location of the antennas of receiver and transmitter
- Type of terrain and degree of obstruction of the link path
- Sources of interference affecting the receiver
- “Dead spots” caused by signal reflections from nearby conductive objects.
Since the expected transmission range strongly depends on this system conditions, range
tests should always be performed to determine the reliably achievable range under the
given conditions.
The following figures should be treated as a rough guide only:
- Line-of-sight connections
Typically 10 m range in corridors, up to 50 m in halls
- Plasterboard walls / dry wood
Typically 10 m range, through max. 2 walls
- Ferro concrete walls / ceilings
Maximum 1 wall or ceiling, depending on thickness and material
- Fire-safety walls, elevator shafts, staircases and similar areas should be considered
as shielded
The angle at which the transmitted signal hits the wall is very important. The effective wall
thickness – and with it the signal attenuation – varies according to this angle. Signals
should be transmitted as directly as possible through the wall. Wall niches should be
avoided.
Other factors restricting transmission range include:
- Switch mounting on metal surfaces (up to 30% loss of transmission range)
- Hollow lightweight walls filled with insulating wool on metal foil
- False ceilings with panels of metal or carbon fibre
- Lead glass or glass with metal coating, steel furniture
The distance between the receiver and other transmitting devices such as computers, audio
and video equipment that also emit high-frequency signals should be at least 0.5 m.
