Error in VOXL mini 4 in 1 ESC diagram
-
Hi,
I am having strange issues with the VOXL2. I had hooked it up with a 4-in-1 mini ESC using the diagram here: https://docs.modalai.com/images/d0014/CWD-D0014-4-CXX-M22-TX-REV2.jpg. It turns out there is an error on the way wiring is shown (see the red circle):
With that wiring, I was unable to get the LTE v2 pro modem working. It was not being detected. I was also not able to get any battery info.
Now I have fixed the wiring as per the pinout of the connectors. But I am seeing the following issues:
- still I am not able to detect the LTE v2 modem.
- still no battery info. When I try to manually stop/start the "voxl_esc" driver in PX4 mavlink console, it gives me errors and fails to start.
- ADB over usb C does not work if the ESC UART connector J18 is not plugged into the VOXL 2.
Can you help me? I hope nothing is burnt/ broken due to the error in wiring above

@Alex-Kushleyev the RX and TX lines need to be swapped at the J18 connector as well, please
