Hi Bakas,
Long back I worked on this.
I don't exactly remember what I did to overcome those errors.
May be somewhere in below link tutorials you may find the solution which you are looking for:

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.
