Check COM port permissions, BLE pairing, and ensure bootloader mode is active.

1. Sorry it's NOT supported because the expansion shield's Serial port0 are connected with the Mega I/O pin 0,1 directly, so it can only be updated wirelessly by other BLE device.
2. If you use IO Expansion Shield for Arduino V7.1, it's no problem then. Only note that you have to turn the switch to Prog when it was going to update other BLE device. On the contrary, turn it to RUN when it was regarded as the receiver.
3. Check if you plugged the BLE link module in the expansion shield reversed.
4. A suitable power supply is required. One of our customer use 5V@8A adapter to power a BLE card, even he tried everythinig, he just can not make it, once it was replaced by a simple USB cable from computer, it got success then.
