Hello everyone, currently I am writing a program to read the SCD41(I2C) sensor and then use BLE to transmit information. With a separate program in twi_sensor, I see that the sensor is working, then I add the necessary files and edit a few files like sdk_config, add nrf_twi.c. Finally, when building, everything says completed.
However, I discovered a problem: the advertising part doesn't seem to work (the light on the board doesn't flash and when using nrf connect on the phone, it doesn't find device name to connect). Then I tried using the ble_app_uart file (without the sensor), I added a line of code printf("Hello") and I realized the same situation, the advertising part also didn't work although all reported a successful build.
Hope everyone can help me?
