2 Factory Test Mode
Factory test mode is customizable depending on user’s requirement, and it’s not
supported by all RC demos.
Following shows an implementation example:
Press the specific combination buttons (to be determined), power on the RC with
the buttons held, the indicating LED of the RC will blink to indicate the RC enters
factory test mode.
In factory test mode, the RC won’t send pairing/adv packet unless specific button
is clicked. This mode is used to test key values in a controlled way (e.g. user can
determine when to send pairing/adv packet).
The RC will exit factory test mode and enter normal state by clicking specific
button.

3 Factory Reset Mode
Factory reset mode is customizable depending on user’s requirement, and it’s not
supported by all RC demos.
After the RC is powered on, if it’s not connected to the demo dongle, the factory
reset mode (if supported) can be triggered by pressing the specific combination
buttons (to be determined) for several seconds (to be determined). The indicating LED
of the RC will blink several times (to be determined) to indicate the RC is reset to its
factory default state.
4 Pairing and Un-pairing
NOTE: The RC needs to be paired with the demo dongle before it can be used. Telink
samples provided to customers are already paired, so the pairing steps in this section
can be skipped.
Before pairing operation, both the RC and Dongle should be burned with the
right firmware, respectively. Telink-supplied RC and Dongle samples are preloaded
with FW already. If user needs to update the FW, please follow the operations as
described in the document “AN_FBD-EVK-UG_Firmware burning and debugging
User Guide” or implement OTA upgrade (see section 9).
The RC demo supports pairing and un-pairing initiated by the demo dongle side.
4.1 Pairing between RC and dongle
The pairing operation is as shown below:
1) Power on the BLE RC. Insert the BLE Dongle into PC.
2) Click the “SW1” button of the BLE Dongle to start pairing process.
3) The red LED light on the BLE Dongle will be turned on and keep the state always
to indicate successful pairing.

Specification For Telink 8258 Mesh RCU TLSR8258MRC48
4) After power cycle the paired RC/Dongle, it’s not needed to click the “SW1”
button again and the RC will be paired with the Dongle automatically.
5) After the BLE RC is successfully paired with the Dongle, if the RC is powered
down or the communication is disconnected, the white indicating LED light on
the Dongle will also be turned on. Power on the RC again or reestablish the
communication, the white light will be turned off.
4.2 Un-pairing
Once paired with the Dongle, the RC can be manually unpaired using the
following sequence:
1) Click the “SW2” button of the BLE Dongle to start un-pairing process.
2) The red LED light on the BLE Dongle will be turned off to indicate successful
un-pairing.
5 Button Function
After the BLE RC is successfully paired with the Dongle, the RC can send certain
key value by pressing corresponding button. The function of each button is shown as
in Section 1.2.
To test the simple button input, no special PC tool is needed. User can open up
Notepad on the PC with dongle plugged in, key presses such as 1, 2, 3, …, will be
directly taken as input to the text file.
User can also use PC tool (KeySimulator) to simulate button press, release and
repeat on the RC.

6 Low Battery Detect
Telink RC sample supports low battery detect function.
The implementation method of low battery detect function is customizable
depending on user’s requirement. One typical implementation is shown as below:
When battery voltage drops below 2.0V, the indicating LED of the RC will fast
blink three times, and then the RC will be shut down automatically. In this case, user
should replace the battery.
*Note: Frequency and number of times of the indicating LED blinking are
customizable.
7 Repeatable Buttons
Each button on the RC is customizable as repeatable button depending on user’s
requirement.
For example, generally the following group of buttons can be customized as
repeatable buttons:
- Left
- Right
- Up
- Down
Under BLE mode, when the repeatable buttons are pressed and held, the key
values will be sent at 250ms (configurable) intervals.
Except for the buttons customized as repeatable buttons, all the other buttons are
treated as non-repeatable keys.
8 Couch Time
Couch time is customizable depending on user’s requirement, and it’s not
supported by all RC demos.
This feature is used to save power for RC when some button is pressed by
mistake and held for a long time.

Specification For Telink 8258 Mesh RCU TLSR8258MRC48
- The RC will only transmit one packet if a non-repeatable button is pressed
and held.
- However, if a repeatable button is pressed and held, it will keep transmitting
packets for up to 60 seconds (normally) after which the RC will stop
transmitting until the pressed button is released.
9 OTA firmware upgrade
This feature is used to upgrade the RC firmware using the Telink PC tool (Key
Simulator), a burning EVK and the dongle demo.
The operation is described as below:
1. Download new Firmware (FW) into the dongle.
1) Connect hardware: Connect the burning EVK with PC via an USB cable, and
connect the dongle with the EVK via USB interface.
FCC COMPLIANCE STATEMENT:
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired

3) After the FW is successfully downloaded into the Dongle, the log window of
the interface is shown as below:

2. Insert the dongle into PC USB. Make sure that the RC is connected with the
dongle in BLE state (i.e. the red light of the dongle is on, and the white light is off),
at the same time the button function should be OK.

3. Click the “OTA Start” button on the “KeySimTool” interface (as shown in Figure 4),
the blue light of the dongle (as shown in Figure 2) will be turned on to indicate
the dongle is in OTA mode.
4. When the blue light of the dongle is turned off, the OTA process ends. The OTA
result can be checked in the log window of the “KeySimTool” interface.
