Hi guys,

I’ve observed a couple of issues when routing serial data through the Rpi.

I am using a teensy to send serial string to 0.0.0.0 port 1240 via the USB port on the Rpi.

On the bench, with 1 meter of ethernet.

I have observed that when I start the pi. I will not get any comms running until I disconnect the Teensy. (can’t access 192.168.2.2:2770 and no comms on QGC)

I am running companion 0.19

When I do get my serial data (BAUD 115200) I have A LOT of dropped packets.

My string is about 100 characters long and I am sending it at 5Hz.

Any idea how to improve this?

Cheers,  
E.
