BLE_UART for driving STS Servo (LeRobot SO101)

Arduino SDK

Hi, @Pammy:

If I want to use BLE UART for Serial2 to STS Servo,
which AMB82-MINI example code should I use ?

Thanks !

Hi @rkuo2000,

There are two examples you can explore.

BLEUARTService:

BLEUARTClient:

Here are a few suggestions you can try.

For communicating with the STS servo, you can keep the existing Serial usage as-is and add Serial2 as a separate UART interface for the servo.

For example, you can:

  • Add Serial2.begin({baudrate}); in setup() using the baud rate required by your STS servo.
  • Forward the data received through BLE to Serial2 in writeCB().
  • Read the response from Serial2 in loop() and send it back through BLE.

So the main idea is to use BLEUartService.ino as the base example and replace/add the UART data path with Serial2 for the STS servo.
