Bluetooth Classic Architecture
Figure 2: Bluetooth Software Architecture
Application
The application layer launches the Bluetooth stack and uses commands to access various profiles on remote
Bluetooth devices over the network.
Profiles
There are number of Bluetooth profiles defined in the Bluetooth specification. This design currently supports profiles
including Serial Port Profile (SPP), provided framework to develop new profiles very easily. We will continue to add
new profiles.
Bluetooth Core
The Bluetooth core contains the following higher layers of the stack.
• RFCOMM
• SDP
• L2CAP
• HCI Generic Driver
• HCI BUS Driver
RFCOMM is a transport protocol based on L2CAP. It emulates RS-232 serial ports. The RFCOMM protocol supports
up to 60 simultaneous connections between two BT devices. RFCOMM provides data stream interface for higher level
applications and profiles.
SDP (Service Discovery Protocol) provides a means for applications to discover which services are available and to
determine the characteristics of those available services. SDP uses an existing L2CAP connection. Further
connection to Bluetooth devices can be established using information obtained via SDP.
L2CAP (Logical Link Control and Adaptation Protocol) provides connection-oriented and connection-less data
services to upper layer protocols with data packet size up to 64 KB in length. L2CAP performs the segmentation and
reassemble of I/O packets from the base-band controller.
HCI Generic Driver – This driver implements HCI Interface standardized by Bluetooth SIG. It establishes the
communication between Stack and HCI firmware in the Bluetooth hardware. It communicates with the Bluetooth
controller hardware via the HCI Bus driver.
HCI Transport Layer Driver – The Bluetooth controllers are connected to the host using interface like UART, USB,
SDIO, SPI, USB-CDC etc. The HCI Transport Layer Driver provides hardware abstraction to the rest of the Bluetooth
stack software. This driver makes it possible to use Bluetooth stack with different hardware interfaces.
Bluetooth Profiles are additional protocols that build upon the basic Bluetooth standard to more clearly define what
kind of data a Bluetooth module is transmitting. While Bluetooth specifications define how the technology works,
profiles define how it's used.
RS9116W BT Classic AT Command Programming Reference Manual
Version 2.1
silabs.com | Building a more connected world. 6 | Page
The profile(s) a Bluetooth device supports determine(s) what application it's geared towards. A hands-free Bluetooth
headset, for example, would use headset profile (HSP), while a Nintendo Wii Controller would implement the human
interface device (HID) profile. For two Bluetooth devices to be compatible, they must support the same profiles.
OS Abstraction Layer
This layer abstracts RTOS services (semaphores, mutexes and critical sections) that are used by the whole stack and
the applications. The stack, which is designed in an RTOS-independent manner, can be used with any RTOS by
porting this layer. It is also possible to use the Bluetooth stack standalone without RTOS.

2 Bootloader
This section briefs about features that are supported by Network and Security Processor (NWP) bootloader. It is
applicable for RS9116 WiSeConnect.
Basic Features
• Load default firmware
• Load selected firmware
• Upgrade firmware from host
• Selecting default images
• Enable / Disable host interaction bypass
• Support for multiple host interfaces (SDIO / SPI / UART / USB / USB-CDC)
• Firmware integrity check
• Upgrading Keys
• JTAG selection
The RS9116W module supports two boot loading modes:
1. Host Interaction (Non-bypass) Mode:
In this mode host interacts with the bootloader and gives boot up options (commands) to configure different boot
up operations. The host tells the module what operations it has to perform based on the selections made by the
user.
2. Bypass Mode:
In this mode bootloader interactions are completely bypassed and uses stored bootup configurations (which are
selected in host interaction mode) & loads default firmware image in the module. This mode is recommended for
final production software to minimize the boot up time.
Host Interaction Mode
In This mode host interaction varies based on host interface. Host interaction in SPI / USB and UART / USB-CDC are
different. In UART & USB-CDC boot up options are menu based and in SPI / USB using command exchanges. The
details are explained below.
Host Interaction Mode in UART / USB-CDC
This section explains the host interaction mode in UART / USB CDC mode.
Startup Operation
After powering up, host is required to carry out ABRD (Auto baud rate detection) operation. After successful ABRD,
the module displays the menu of bootup options to host. The host needs to select the appropriate option.
Note:
On powerup, bootloader checks the integrity of the bootup options. If the integrity fails, it computes the integrity
from backup. If integrity passes, it copies the backup to the actual location. If the integrity of the backup options
also fails, the bootup options are reset/cleared. In either of the cases, bootloader bypass is disabled or
corresponding error messages are given to host. In case of integrity failure and when the backup integrity check
passes, "LAST CONFIGURATION NOT SAVED" message is displayed. When backup integrity also fails,
“BOOTUP OPTIONS CHECKSUM FAILED" is displayed before displaying the bootup options.
Hyper Terminal Configuration
RS9116W uses the following UART interface configuration for communication:
Baud Rate: The following baud rates are supported by the module: 9600 bps, 19200 bps, 38400 bps, 57600 bps,
115200 bps, 230400 bps, 460800 bps, 921600 bps.
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

Set the following values for the fields shown in the Figure 6.
• Set baud rate to 115200 in "Bits per second" field.
• Set Data bits to 8 in "Data bits" field.
• Set Parity to none in "Parity" field.
• Set stop bits to 1 in "Stop bits" field.
• Set flow control to none in "Flow control" field.
• Click "OK" button after entering the data in all the fields.
Auto Baud Rate Detection (ABRD)
The RS9116W automatically detects the baud rate of the Host's UART interface by exchanging some bytes. The Host
should configure the UART interface for the following parameters for ABRD detection.
RS9116W uses the following UART interface configuration for communication:
Baud Rate: The following baud rates are supported: 9600 bps, 19200 bps, 38400 bps, 57600 bps, 115200 bps,
230400 bps, 460800 bps, 921600 bps.
Data bits: 8
Stop bits: 1
Parity: None
Flow control: None
To perform ABRD on the RS9116W, the host must follow the procedure outlined below.
1. Configure the UART interface of the Host at desired baud rate.
2. Power on the RS9116W.
3. The Host, after releasing the module from reset, should wait for 20 ms for initial boot-up of the module to complete
and then transmit 0x1C at the baud rate to which its UART interface is configured. After transmitting '0x1C' to the
module, the Host should wait for the module to transmit 0x55 at the same baud rate.
4. If the '0x55' response is not received from the module, the host has to re-transmit 0x1C, after a delay of 200ms.
5. After finally receiving '0x55', the host should transmit '0x55' to the module. The module is now configured with the
intended baud rate.
Note:
Performing ABRD in host interaction mode is must for USB CDC mode.

Software Protocol
AT+ command mode
This section explains the procedure that the host needs to follow in order to send Wi-Fi commands frames to the
module and to receive responses from the module in AT+ command mode.
TX Operation
The Host uses TX operations:
1. To send management commands to the module from the Host.
RS9116W BT Classic AT Command Programming Reference Manual
Version 2.1
silabs.com | Building a more connected world. 20 | Page
2. To send actual data to the module which is to be transmitted onto the air.
3. If the host receives error code indicating packet dropped, the host has to wait for a while and send the next
command /data.
4. The host should send next data packet only if it receives "OK<number of bytes sent>" response for the previous
one.
Rx Operation
The RS9116W responds with either an 'OK' or 'ERROR' string, for Management or Data frames along with a result or
error code.
The module sends the response/received data to Host in a format as shown below:
Figure 16: RX Frame Format
Note:
If Payload offset is 'x', 'x-4' dummy bytes will be added before Frame Descriptor.
The host needs follow the steps below to read the frame from the Module:
Read 4 bytes using Frame read.
1. Decode Total payload length and payload offset.
2. Read remaining payload by sending Frame to read with (total payload length – 4 bytes), discard Dummy bytes
and then decode Frame descriptor and Frame Body.

4 Classic Command Mode Selection
This section describes AT command mode or Binary mode selection in UART and USB-CDC. It is applicable for
RS9116 WiSeConnect.
After boot-loader interaction, module gives "Loading Done" string in ASCII format to host.
After receiving "Loading Done", based on first command received from host, the module selects command mode.
The module reads first 4 bytes, if it matches with "AT+R", select AT command mode, otherwise select Binary mode.
Once mode is selected, it will remain in same mode until it is reset or power cycle.
There is an option in bootloader to select AT mode or binary mode.
Note:
"AT+R" is not case sensitive.

5 Classic Command Format
This section explains the general command format. The commands should be sent to the Module in the specified
format. It is applicable for RS9116 WiSeConnect. Commands are sent to the module and responses are read from the
module using frame write/frame read (as mentioned in the preceding sections). These commands are called as
command frames.
The format of the command frames is divided into two parts:
1. Frame descriptor
2. Frame Body (Frame body is often called as Payload)
Frame Descriptor (16 bytes)
Frame Body (multiples of 4 bytes)
Command frame format is shown below. This description is for a Little-Endian System

Three types of frames will get exchanged between the module and host.
1. Request/Command frames
o These are sent from Host to Module. Each Request/ Command has an associated response with it.
2. Response frames
o These are sent from Module to Host. These are given in response to the previous Request/Command
from the Host. Each command has a single response.
3. Event frames
o These are sent from Module to Host. These are given when there are multiple responses for a particular
Request/ Command frame. This is Asynchronous message to be sent to host.
The following are the types of frame requests and responses and the corresponding codes. The commands are
different for both Classic and LE modes. The below table lists the Command, Response and Event frames in Classic
mode.
