How to check whether is the device bonded?

[inghowe83]

Hi,

How to check whether is the device bonded? What value I could check? What I want to do is to perform auto pairing request when bonding is not founded, therefore my code will try to check whether the device is bonded before. If yes, it will skip the advertising process.

I also encounter a problem, after I pair and bond using  ble_app_hrs_freertos example I just cannot unbond the device (it cannot appear in normal BLE scan, only can detect using Nordic Connect). Please advice how can I unbond the example. And when I tried to call pm_peers_delete( during BLE_GAP_EVT_DISCONNECTED, the device enter NRF_BREAKPOINT_COND.

HW:PCA10056

SW:nRF5_SDK_15.2.0_9412b96

Example:

ble_app_beacon

ble_app_hrs_freertos

As far as I know, the nordic nrf connect app display as bonded and I cannot scan the advertising from the board in my usual BLE scanning (so I assume its already bonded).

And yes I tried added APP_ERROR_CHECK to check the pm_peers_delete(), it don't work as it will enter NRF_BREAKPOINT_COND through CRITICAL REGION ENTER just before the function return. I perform the pm_peers_delete() after I disconnected the ble (BLE_GAP_EVT_DISCONNECTED)

Did you put a breakpoint at app_error_fault_handler() and debug the code?

Hi,

I managed to get it fix from the following post.
