Hi everyone,

I'm facing an issue where the FC (GEPRC 722 AIO) does not seem to send an arm signal to the Vista Unit. Currently using the latest vista firmware. I have since rewired it from UART 1 to UART4, and also used the plug/Direct solder +/- to battery lead. i have double checked the MSP. Everything seems to be in order.

The betaflight OSD is working properly, reading voltage properly however the DJI OSD Batt Voltage display is at 0.0V, and the vista does not go out of low power mode on arm (Stuck at 5MBPS).

Another fix that i have also tried is removing all the diodes. Still does not solve the MSP Arm issue.

Any help is appreciated. Thanks in advance

hello, I am having the same problem. any solution?
