GPS not connecting to Voxl 2
-
Hi,
I'm attempting to plug in a Zed-F9P into a VOXL 2's J19 connector and it doesn't seem to work. I've tried to query the GPS but it returns as no device found. I've moved to make sure the J19 port is working by shorting the TX and RX pins and sending data over RX while listing with busybox. I'm not able to receive any data from TX through this method.
Is it possible my VOXL connector is broken or am I doing something wrong?

@alan123 Based on this other user's feedback (https://forum.modalai.com/topic/4403/starling-2-max-with-ublox-f9p-ultralight/2?_=1762378810994) it seems like that module isn't supported by our current PX4 build. New PX4 releases seem to support it. Not sure what the issue is with our build as we have never tried to support this module.

@Eric-Katzfey Understood. Will look into this. Do you have any idea why my J19 Port testing method failed? How can I make sure that the issue is not stemming from the port itself?

@alan123 I would try running voxl-px4 from the command line instead of as a service and looking at the messages to see if there are any obvious errors being reported. (e.g.
systemctl disable voxl-px4,systemctl stop voxl-px4, wait a few seconds, thenvoxl-px4 -d) -
@alan123 If it keeps reporting changing to a new UART baudrate then that's an indication that it isn't connecting at all to the GPS unit. You could also put an oscilloscope on the lines to see if you can detect traffic from the GPS and from VOXL 2.
