Error code 4 in pm_peer_rank_highest()

[Cusko]

In code:

case PM_EVT_BONDED_PEER_CONNECTED:
  NRF_LOG_DEBUG("Connected to previously bonded device\r\n");
  err_code = pm_peer_rank_highest(p_evt->peer_id);

i get err_code=4 if I try pairing with Windows 10. But if I pair with Windows Phone 8.1, I don't get any error. Any idea?

SDK v12.1.0

Not really, but 4 is NRF_ERROR_NO_MEM, and I guess it is returned from pdb_raw_store() inside pm_peer_rank_highest(). Can you confirm? pdb_raw_store() will return NRF_ERROR_NO_MEM when there is no space in persistent storage.

[Cusko]

Yes, pdb_raw_store() returns NRF_ERROR_NO_MEM.

Does this also happen if you erase the complete flash, reprogram SoftDevice+application and bond with Windows 10?

[Cusko]

No, if I erase complete flash and reprogram I could connect normally to Windows 10. Why? What is story behind this?

[Petter Myhre]

Ok. Then I guess there wasn't any more space in persistent storage (flash), you had too many bonds stored.
