How to delete all pairings
Hi,
My ble_app_hrs_freertos also encounter NRF_BREAKPOINT_COND in debug after run pm_peers_delete. Please advice.
HW: PCA10056
SW:nRF5_SDK_15.2.0_9412b96
example: ble_app_hrs_freertos

What's the return code from pm_peers_delete?
Hi,
I checked, it didn't even completed progress through the whole pm_peers_delete function. The NRF_BREAKPOINT_COND happens when evt_send(&pm_delete_all_evt) is called.
My device already pair with the phone via nrf connect mobile app. Not sure why it shown no peer id
evt_send calls the event handler of the first event handler registered through pm_register (first loop), this might be the function pointer in m_evt_handlers[0].
That event handler is the next clue of our mystery. I'm guessing that it contains the APP_ERROR_CHECK that processed a non-NRF_SUCCSESS return code, thereby calling the error handler.
Thanks. What should I do next, I kinda out of idea about this. As the whole driver code is like a black box to me.
Here is the debug crush disassembly.
