Teltonika Qualtec EC25 modem tester

Program that tests Qualtec EC25 modem using AT commands of these device series:

• RTXxx
• TRM2xx
• RUT9xx

Program tests any device from device list in config file when given parameter -D, for example: sudo python3 ./main.py -D RUTX11.

Note: the device must defined in config file. Config JSON file example.

It connects to device via SSH or Serial Port and tests modem using AT commands. The program reads all data of a given device from config file and other arguments (or default argument values) if such device exists. A connection is established if given parameters are correct (serial port device, SSH port, IP address, auth credentials, etc.) and if the device is connected and is avaliable.

Program tests if given commands' return value is as axpected (see config file example) and forms result file. Some commands may return multiple lines (executing multiple arguments) and may take up to 180s to test, if command does not return expected result under 180s then it is consider that command failed.
