Blocking /dev/ttyS0?

Hello everyone,

I want to read from serial /dev/ttyS0 (or AMA0?) and do stuff with it via a python script.

When I execute “cat /dev/ttyS0” there is no print. It just hangs.

Is any process using /dev/ttyS0?

My setup works just fine when using another SD Card with regular raspbian image. So my guess is that pwnagotchi is occupying the serial port somehow?

Thanks in advance!

Nobody?

PS: I am using this neo 6m gps module.
