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 Surya, 

What is the version of SDK you are using?

Can you also add the debug log here by adding DEBUG to your preprocessor definitions? Also enable logging in Peer Manager and PM_LOG_LEVEL to debug.

// <e> PM_LOG_ENABLED - Enable logging in Peer Manager and its submodules.
//==========================================================
#ifndef PM_LOG_ENABLED
#define PM_LOG_ENABLED 1
#endif
// <o> PM_LOG_LEVEL  - Default Severity level
 
// <0=> Off 
// <1=> Error 
// <2=> Warning 
// <3=> Info 
// <4=> Debug 

#ifndef PM_LOG_LEVEL
#define PM_LOG_LEVEL 3
#endif

Please upload the debug log to help identify the issue.

I am getting the following in Log

<error> peer_manager_pds: Could not write data to flash. fds_record_{write|update}() returned 0x8601. peer_id: 0
<error> peer_manager_pds: Could not delete peer data. fds_file_delete() returned 0x8601 for peer_id: 0

Hi Surya, 

0x8600 is the base number for FDS errors, that is, FDS errors start at 0x8600 and goes upwards. Looking at the FDS return values, the first error is 0x8600, the next one 0x8601, and so on. 0x8601 is FDS_ERR_NOT_INITIALIZED. According to the fds_record_write() documentation, this error means the module is not initialized. 

Please check pds is initialized.

I am using peer_manager and initialising before calling pm_peer_new(). is there any module I have to initialise for this, Other than peer_manager() ?. 

[Surya]

is there anybody to give a solution?

Hi Surya, 

Sorry for the delay. You might check this similar post can help or not.

No, the file is already added to project.

Please set PM_LOG_LEVEL to 4 in the sdk_config.h and provide the debug log. Thanks.

[Surya]

same log is coming. no <debug> information is printing even after setting PM_LOG_LEVEL  to 4
