Hey, Which works. I can also access the console via I tried out the first test again: https://labgrid.readthedocs.io/en/latest/getting_started.html#running-your-first-test My problem is that I don't really have a clue where to start, the serial port seems to work, I can access the device via SSH, the user account works and I can communicate with the exporter without problems. I would be really happy if someone could help me out with this problem. Greetings, |

Hey @Emantor , It seems like I receive empty input bytes, could my configuration be incorrect? Raspberry_Pi_libcamera:
location: Testbox_1
USBSerialPort:
match:
'@ID_PATH': platform-xhci-hcd.1.auto-usb-0:1.2
speed: 115200
NetworkPowerPort:
model: eg_pms2_network
host: 192.168.178.29
index: 1Like I said I can access the Raspberry Pi via serial port without problems from the exporter device. To give a better overview of my setup here is a small graph: And here is the output of the pytest output with -vvv: Programming_Projects/PyProjects/labgrid_test via 🐍 labgrid-venv

From the log it looks like we are only sending bytes via pyserial, but are not reading anything. That's weird. Is the console still open somewhere else? In that case the other program may receive the output instead of labgrid reading the output. |

@Emantor 1. Prepare Raspberry Pi:

This is definitely our bug. It looks like the rpi console uses a VT100 code which is not correctly filtered by the VT100 regex within the shelldriver. The failing regex is: but it reads: which does not match since the |

Hey, I just wanted to quickly ask if you know a good way to debug why a login for the activation of a shell driver times out.
The configuration for the login prompt and the login data looks like this:
And I try to activate it like this:
But the problem is that it just times out. Without any clue about where the problem may be. The user exists and the raspberryPi and the prompt looks like this:
testlab_user@raspberrypi:~ $, which I checked in a regex tester and which is matched except for the $ sign.I have also attempted to use the
CommandProtocoldirectly and I tried to get a ShellDriver object directly like this:Greetings,
Sebastian
