Almost a year ago I bought my Zenmuse H3-2D from a local DJI dealer.They no longer stocked the P1 version and sold me the P2 only version. I have a P1.1.1 with the upgrade board. Obviously the mounting brakets were different and the dealer was more than helpful sorting that out. My gimbal has always functioned as it should with one exception. It would never connect to the assistant software. I've installed, uninstalled, and re-installed drivers. I've tried to connect the USB both before and after powering up the P1. I am beginning to suspect that the P2 version may have a slight code difference. I wouldn't think so, but not sure what else it could be. Any thoughts or ideas?
