@ravi It's acting like you have a mismatch in baudrate settings for the UARTs. Try setting the baudrate to 115200 for port 12 in /etc/modalai/voxl-mavlink-server.conf. In order to setup the FCv2 connect to QGC with USB and set SER_TEL1_BAUD to 115200 8N1, then reboot. Make sure you are connected to the TELEM1 connector on FCv2 and J18 on VOXL 2.

RE: GPS not connecting to Voxl 2posted in Ask your questions right here!
@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.

@bambamoda What you're trying to build sounds a lot like a bigger version of our stinger fpv drone: https://docs.modalai.com/stinger-vision-datasheet/

RE: VOXL 2 J18 port for External FCposted in Ask your questions right here!
@Jetson-Nano Looks like you are never receiving anything FROM the AP. Only sending stuff TO it. Can you put an oscilloscope on the RX / TX UART lines to see what the traffic looks like. For some reason it doesn't seem like the UART is setup properly on either the FC or the DSP so with an oscilloscope you can better see what is going on.

@Jetson-Nano Are you using WiFi to connect with QGC?

@Jetson-Nano Do you still get those messages from voxl-mavlink-server about dropped packets from external AP?

@Jetson-Nano Can you try a lower baudrate, like 57600, and see if that works better?

RE: Update UDP Port for the voxl-mavlink-serverposted in VOXL SDK
@brandon The latest voxl-mavlink-server is available here: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-mavlink-server_1.4.12-202511040816_arm64.deb. This has added configuration for the GCS ports and also fixes the above issue so that it now responds to the correct port.
