@modaltb Hey, thanks for the quick reply. Unfortunately, none of these work for us since it seems exposing one port prevents us from accessing another (I also can't find a ref to buy the M0130).

We found a workaround by having a USB hub on the m0125 instead of going over the native uart.

@Filip-Slezak-0 Thinking about ttyHS2 or ttyHS3 maybe shown here https://docs.modalai.com/voxl2-linux-user-guide/#uarts

@Eric-Katzfey Hi again, can we expose another UART port for programming on the Voxl2?

Hi dev team,

How should we proceed to run/update to custom px4 firmware? We want to execute specific actions controlled through mavros

On a pixhawk it works through the QGC firmware flashing tool, what's the alternative to that for the Voxl2?

Best,
Filip

@Eric-Katzfey Thanks Eric, got it working easily after that using a classic pyserial script. Great help!

@Eric-Katzfey Got it, this is getting clearer. Is it safe to use the Teensy's 3.3V pins? According to this, the Voxl2 comm pins are at 1.8V even though its GPIOs are at 3.3V https://docs.modalai.com/voxl2-linux-user-guide/#devttyhs1---b2b-connector-uart

@Eric-Katzfey So you're thinking switch out the boards, use the UART for the wifi dongle and communicate over USB with the microcontroller?

@Eric-Katzfey Sorry for the late reply. Unfortunately, I don't see how that could work for us, we already have the m0078 on there and the J2 goes to the wifi dongle, what am I missing in what you're suggesting?

@Eric-Katzfey No worries, and yes that's it. How would you recommend I communicate with that external Teensy board? Can't seem to find easily accessible pins for that.

@Eric-Katzfey Hey, I have to reply from another account because the email system for confirmation doesn't work (fyi)

We have the bigger standard Voxl2, not mini.
