Serial shell PIXFALCON ttyS1

Hello. I am able to open up the serial shell (to access the command line) through ttyACM0 (micro usb port).

But, Is it possible to open up the serial shell from another UART or I2C (example, ttyS1/TELEM1) ?

An FTDI 3.3V cable is being used for that, as it has been done with pixhawk here!topic/px4users/NVBtASKSlBs

Did you see that you can use the shell via MAVLink? This is generally more convenient.
Otherwise you should be able to use nshterm /dev/ttySx.

Hi bkueng,

i had not tried that until now and that helped, it worked through ttyS1 with mission planner `s console.

Thank you.
