Cannot pair BTLE Keyboard using HOGM

Roland-B
Intellectual 420 points

Hello all,

I have problems to connect a BTLE-Keyboard using HOGM.
I use a WL18xx on a AM335x Board with the BT-Stack AM335xBluetopiaLinuxProduction-4.0.3.0.1.0.

This is what I do:

  • ./SS1BTPM & ./LinuxHOGM
  • Initialize 1
  • SetDevicePower 1
  • RegisterEventCallback
  • RegisterHOGMCallback
  • RegisterAuthentication
  • StartDeviceDiscovery 1 11
    ...
    My Keyboard with ID FABADE98212C is recognized
  • PairWithRemoteDevice FABADE98212c 1

Attempting to Pair With Remote LE Device: FABADE98212c.
DEVM_PairWithRemoteDevice() Success: 0.
.....
HOGM>
LE Remote Device Pairing Status: FABADE98212C, FAILURE (0x8000001F)

After PairWithRemoteDevice() nothing happens.
There is no question for a Pincode or sth else.
After a Timeout of 30 sec the pairing status is Failed.

What is wrong with my approach?
Below some more information.

Regards,
Roland

    Can, you try with invoking, "SetPairable" on the Host side, before 'pairing'?

    Thanks

    The Host is already pairable, see output of QueryLocalDeviceProperties.
    Any additional setpairable does not change anything.

    Hello Hari,

    thank you for your investigation.

    Meanwhile I found the reason for the HOGM issue:
    I have to
    - first connect the device
    - then pair the device

    When I do the pairing first, then the keyboard changes its BT-Address and connecting fails.
    This occured both with a BT-LE Keyboard and mouse.
