Programming and Debugging

Flashing

The byteSENSI-L board can be flashed with the SEGGER JLink programmer. You can build the following samples as demo application:

1. Build the Hello World sample:

$ west build -b bytesensi_l samples/hello_world
$ west flash

2. Build the LPS22HB: Temperature and Pressure Monitor sample:

$ west build -b bytesensi_l samples/sensor/lps22hb
$ west flash

3. Build the TI_TMP116 Sample sample:

$ west build -b bytesensi_l samples/sensor/tmp116
$ west flash

4. Build the APDS9960 RGB, Ambient Light, Gesture Sensor sample:

$ west build -b bytesensi_l samples/sensor/apds9960
$ west flash

5. Build the CCS811 Indoor Air Quality Sensor sample:

$ west build -b bytesensi_l samples/sensor/ccs811
$ west flash

6. Build the LoRa samples:

Using two byteSENSI-L, you can run the LoRa send and receive demo:

$ west build -b bytesensi_l samples/drivers/lora/receive
$ west flash

$ west build -b bytesensi_l samples/drivers/lora/send
$ west flash

7. Build the soc-flash-nrf sample:

$ west build -b bytesensi_l samples/drivers/soc_flash_nrf
$ west flash

8. Build the Bluetooth samples:

Most of the bluetooth samples should work out of the box, for example, building the Bluetooth: Peripheral HIDs sample:

$ west build -b bytesensi_l samples/bluetooth/peripheral_hids
$ west flash

Debugging

Debugging your application can be done with west debug:

$ west debug

Serial console

The byteSENSI-L board only uses Segger RTT console for providing serial console. There is no physical serial port available.
