OcuSync 2.0, O3 & O3+ clarifications?

[GadgetGuy]

Mine was bought standalone, I believe with the .01x (M3) firmware installed. I remember having to upgrade it to the .03x (A2s) firmware.

Yeah, they're all identical.

It's not quite as simple as swapping cameras on the M2, where the app immediately recognizes the change and reconfigures everything appropriately. It still needs to run a locally stored small FW alteration each time you switch drones, and you also have to change the drone's paired RC from the original RC-N1 to the RC-Pro for Refresh purposes with an internet connection each time.
