Hi, I am using the ble_app_cscs_pca10056_s140 example application from nRF5_SDK_15.0.0_a53641a and I have made a single-line change (see below) to force the bonding process to run. This works flawlessly for a new device; I get a bond succeeded and can subscribe to the NOTIFY characteristic. However it fails whenever I disconnect and then try to reconnect.
To try and debug I've added log statements for all Peer Manager events and have included this below. I get a PM_EVT_STORAGE_FULL as part of the initial bond, then a lot of PM_EVT_LOCAL_DB_CACHE_APPLY_FAILED. I think this is suggesting the bond information cannot be stored &/or retrieved correctly from the flash?
I tried running: nrfprog --qspieraseall and nrfprog --eraseall but that doesn't seem to help.
The single change I made to the basic example in services_init() function is:
//BLE_GAP_CONN_SEC_MODE_SET_OPEN(&cscs_init.csc_meas_attr_md.cccd_write_perm); BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM(&cscs_init.csc_meas_attr_md.cccd_write_perm);
Log output:

I'm not sure what to try next to be honest...any help or suggestions appreciated!
Many thanks.
