Hi @adam ,

In the BTM_PAIRING_IO_CAPABILITIES_BR_EDR_REQUEST_EVT. can you set pairing_io_capabilities_br_edr_request.auth_req = BTM_AUTH_ALL_PROFILES_NO and try?

Also can you share the logs so that we can identify the exact error codes for failure?

Thanks and regards,

Hi @adam ,

We had observed this issue on the older SDK versions but it has been fixed in the newer version. Can you let me know what is the version you are using?

Also, I am not able to see the logs that you have shared. Can you please share BTSpy logs?

Thanks and regards,
