VTX Runcam Split 2 Issue

If these uarts behave the same way a USB COM port in Windows does... then the number in Windows may be assigned dynamically when they are plugged in. If so... then when you plug in, you'll hear a notification sound and the device should show up in device manager and tell you what port number that was assigned to it.

If they don't behave the same... then just ignore this post
There is a direct 1-1 correlation between the TX/RX ports and UART ports on the flight controllers. So TX/RX 1 is UART 1, or is it UART3...I can't remember lmao

If you are connected to RX1, then you need to turn on serial Rx on UART1. If in RX3, then UART 3 and RX6, then UART6

I will bet it will work now. Never set that setting to 2048, it will mess with you every time.

New problem. Will not stay bound after power cycle. This is after typing set spektrum_sat_bind = 0 in CLI.

Run this string, then do the 0

set spektrum_sat_bind = 9
set spektrum_sat_bind_autoreset = OFF
save

Bind with the command above, and when you are bound, run the following.

set spektrum_sat_bind = 0
set spektrum_sat_bind_autoreset = ON
save

So I did the above and now it stays bound to the Tx. I need to figure out how to set the modes up with the iX12 now.
