Request your kind support for solving HardFault issue on FRDM KW38 board during BLE operations of a custom app (GAP central) with a mobile app (peripheral).

Target hardware: FRDM KW38

SDK: MKW38A512xxx4  version: 2.6.5

Pairing/Bonding and NVM support are enabled: gAppUseBonding_d is 1, gAppUsePairing_is 1, gAppUseNvm_d is 1.

Pairing security mode: gSecurityMode_1_Level_1_c


Operation sequence:

1. KW38 target app scans and connects/bonds with the phone

2. Phone transfers some app data

3. Initiate disconnect from KW38. After disconnection de-bond the phone at KW38.

After a couple of repeated sequence above, the Hardfault happens (screenshot attached). Any issues at BLE stack side?
