The settings on P20 Pro and Canon EOS are correct, but P20 Pro does no see camera over WiFi or with NFC. The P20 does not see camera's MAC or IP addresses.
Any enlightenment from others would be appreciated.

Thank you for bringing this up to us! At the moment, there are alternatives yet to be provided on this matter, but I will forward this to our developers so this will be looked upon.
While the camera is an external product which is not manufactured by Huawei, we promise to look into this matter and consider this for a future update.
