nRF52 Peer Manager fails with PM_EVT_ERROR_UNEXPECTED

[DevZonee]

Dear DevZonee's

Im trying to esablish a BLE connection using the following configuration of the peer-manager:

* LESC

* Just Works -> IO-Caps none (0x03)

If i run the application on my DK and then try to connect to it via the NRF-Connect, the application crashes.

As mentioned I get the PM_EVT_ERROR_UNEXPECTED event from the peer-manager along with the error code 16 (0x10).

If I switch the LESC flag from 1 to 0, the error no longer occurs, and the connection is successful.

Can anyone explain this behaviour to me? Is it possible to establish a LESC just-works connection?

Hi,

We have several examples in SDK 15.3.0 that have LESC - just works enabled by default, ble_app_hrs for instance. Have you tried any of these, or are you using an older SDK version?

Hi Vidar

Thanks for your response, I've just checked out one of these examples and realised that I've to set the PM_LESC_ENABLED flag and call the nrf_ble_lesc_request_handler() in the main loop. I'm currently working on implementing these changes, but im positive this will resolve my earlier problem.
