Hi
The chip used is nrf52832, the SDK version is a peripheral device v13, and the central device uses v16.
The referenced example is ble_app_multirole_lesc and has been changed to security mode 1 level 4.
The two devices of nrf52832 were well paired, but when I changed the central device to an Android phone and tested it, it was not paired.
What should I do to generate a PM_EVT_CONN_SEC_START event in the peripheral device?
