4 years ago I am experiencing the same issue. Here is an RTT log. It seems that the device disconnects after the BLE_GAP_EVT_CONN_SEC_UPDATE.

It does seem like this should be supported though.
I am using feather_nrf52832 board running the latest bootloader and the BLE UART example from here https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide?view=all It works fine with Android without paring, but with pairing, the board will reboot. But it will go into the application other than doing the update. I am updating using nRFtoolbox and nRF connect app. The error message from both is (0x85) GATT Error.
Is this a feature not implemented?
