Pixhawk-to-RBPi3 interface via USB port



I need to configure RBPi3’s USB port (not micro) as an alternative to TELEM serial connection via GPIOs. Connecting micro USB from Pixhawk to one of them 6 USB ports on RBPi3.



Yes. But what is your question precisely?
Just use USB-UART convertor and connect Pixhawk’s Telem2 port to USB port of Rpi. FlytOS would automatically detect it and latch on to it.


I don’t want to use TELEM2 port on pixhawk, rather its micro USB port connected with the USB port of RBPi3.
I know that pixhawk’s microUSB is used to upload firmware (usb mode). I was wondering if aforementioned is doable?


Yes. Using USB port of Pixhawk for telemetry connection is definitely possible, BUT it is not reliable and MUST NOT be used for telemetry while flying.

You can use it in lab for basic testing and debugging.


Hello I have been constantly facing this issue, my pi and pixhawk are not communicating even tho I have followed all the steps. I have connected using USB-UART, setup baud rate as in flytdocs as well


can you please connect QGC via usb-uart and make sure the hardware connections are right.


I have been able to connect pixhawk with QGC on my laptop using the usual micro USB connection, do you know how i can connect using UART with my laptop?


You have mentioned that you have USB-UART module.
Can you connect the UART end to Pixhawk and USB end to your laptop?


I think I might not have the converter to do this…is there any other way? Kindly open this link to see what i am using currently from TELEM 2 to Pi: https://i.imgur.com/YN6P7qp.jpg
