    bluetoothctl disconnects immediately after pairing successfully



      I'm currently running the Murata's 1DX Wi-Fi and Bluetooth module to the ZedBoard.

      I have a connection problem with Bluetooth: I would like to connect the ZedBoard with my Android phone.

      I can see that everything is OK on the ZedBoard side, concerning the hci0 configuration.


      The serial port used is /dev/ttyPS1 for bluetooth initialization.


      Then I run "bluetoothctl" and I can start the initialization:

      And finally, I "scan on". I can see the ZedBoard on my phone, and the ZedBoard is able to see the smartphone. Everything is OK here. 

      I put "trust xx:xx:xx:xx:xx:xx", and it's accepted. And then I have the info that is somehow encouraging:

      And here is the failing connection. When I run "pair" it returns "successfull", and 5 seconds after it returns "connected: no"

      And it's the same thing when I try from the smartphone.

      The problem remains with v2019.1 and v2020.2

      Can somebody help me to find what is happening?
