Hi,
I am using nrf52810 ,softdevice 132.
I am trying to implement whitelist in ble_app_uart code (peripheral side).I take reference from HID mouse example.
Code compiled successfully but it when i am trying to connect with central it crashed and board reboot. I try to debug the code it shows Error code 4 .
MINICOM LOGS:
<info> app_timer: RTC: initialized.

DEBUG LOG:
void app_error_handler_bare(unsigned int error_code 0x00000004)
Please find the code having changes of whitelist.
