Unauthenticated Pairing - BlueZ to nrf52832

Hey 
I am able to pair my nrf52832 after with the nrf connect phone app
But when trying to do the same with Bluez I am getting authentication error
I use the bluetoothctl tool to do the test .... 
Please see the example below : 
  this is the btmon debug of the session when trying the pairing 

Any idea why the pairing is failing all the time although I am able to pair using the nrf connect phone app ?
Thanks a lot

  • Hi Ibrahim 

    Are you using a standard nRF52DK, or some other hardware? 

    Is there any chance that there is some old pairing data in the nRF52 device that is causing issues when you try to pair with your Linux host? 

    If you perform an erase all on your nRF52 device before programming the application will the same problem still occur? 

    Are you able to view the log output from the nRF52 device in order to see if it provides some more useful information? 

    If all else fails you might want to capture a sniffer trace of the exchange, using either a professional Bluetooth sniffer or the free one we provide: nRF Sniffer
