Troubleshooting

Motors

BGAs / SARJs aren't turning

• Is the power to the motor controller boards on? - Check that the LED on the motor shield on top of each metro board is on
• Is the motor control signal being sent up the HDMI (or whatever) cable? - Check the one of the two diagnostic LEDs on the HDMI shield is lighting up when you try to send a motor turn command (these illuminate when any voltage is sent to the motors).

Software

• If problems with the software occur, errors should be listed in the mimic.log file in the ~/Mimic/Pi/Logs folder. Reach out on discord with the error message if needed. If no error messages, run in debug mode to print out everything: python GUI --debug

Telemetry

Stale Telemetry

• Happens, we can't control this. Sometimes the data goes out.

Can't connect to the telemetry

• Make sure the raspberry pi clock is correct. If the time not correct this causes security issues and the telemetry server won't connect. Use sudo rdate time.nist.gov to update the clock from the command line.

If the pi clock is correct, from the Mimic/Pi folder attempt to run the iss_telemetry.py script on its own. Use python iss_telemetry.py and it should either display an error if its not working or a lot of text constantly updating if it successfully connects to the telemetry server.
