pm_peer_new() causing "PM_EVT_ERROR_UNEXPECTED"

[Surya]

Hi,

I want to add new peer to peer manager using pm_peer_new().

pm_peer_id_t p1 = 0;

pm_peer_new(&p1,&bond_info,NULL);

there are no peers, so trying to add as peer_id 0. but this causing "PM_EVT_ERROR_UNEXPECTED" error in pm_evt_handler() function.

bond_info is filled with information.

Hi Surya, 

PM_EVT_ERROR_UNEXPECTED means an operation failed with an unexpected error. The error is provided. This is possibly a fatal error.

Does pm_peer_new(&p1,&bond_info,NULL); return NRF_SUCCESS? If so, You might step into debugging and checking the error that comes from which function.

Not sure this post can help or not.

Yes it returns NRF_SUCCESS.

Hi,

Are you using the app scheduler by any chance? If so, the Softdevice events (i.e. flash success events) will not get propagated back to the fstorage -> FDS until your program reaches the app_sched_execute(); function in your main loop.

Do you currently have a wait loop that might prevent your program from reaching your idle_state_handle() function?

[Surya]

yes, schedular is used in my case. I am using a delay (nef_delay_ms(25000)) alone and wait loop alone.

for wait-loop it is not coming out of loop.

for delay error 0x8601 causing

Thanks for confirming. So the event will never come through, regardles of how long the delay is. Try to call app_sched_execute(); from your wait loop until the ''init' flag is set.

[Surya]

it's working but few times (once in 10 times) it is not coming out of the wait loop. how to handle this?

[Vidar Berg]

Can you post relevant code here please?

Thanks for posting the code. 'bFDSInitialized ' should be declared 'volatile'. Can you try that?
