Hi,

For how to enable Bluetooth I recommend checking out our existing Bluetooth samples in nRF Connect SDK. You can find the examples under <ncs_installation>/nrf/samples/bluetooth, and documentation for the samples can be found here: Bluetooth samples. The Peripheral LBS sample is a simple example that works well as a starting point.

Best regards,

Marte

You can enable Bluetooth on the nRF52840 DK using the Peripheral LBS sample from nRF Connect SDK — it’s under nrf/samples/bluetooth/peripheral_lbs. Build, flash, and connect via the nRF Connect for Mobile app to test pairing.

If you just want quick serial Bluetooth without BLE coding, try a JDY-31 3.0 SSP Bluetooth Module, it offers simple UART-to-Bluetooth 3.0 communication and pairs easily with Android.
