Code to test AT commands with SIM7000 ESP32 module from Thonny console or command line
uses microPython
Enter the command CTRL-START to start/restart the SIM module
By default a \r (CR) character is added at the end of your command before sending
Add <ncr> to the end of the command if you desire NOT to send a \r (CR) at the end
Example: +++<ncr> to send only the + characters without CR
Enter <cr> To only send \r (CR). All other data on the line will be ignored
Enter <eof> to send the EOF \x1A character
Tested with LilyGO TTGO T-SIM7000G
Notes:
Some commands (like +++) require a 1 sec no data before sending and a 1 sec delay before sending \r.
Therefore there are 1 sec delays in de code before the \r characters are send.
Example with Thonny interpreter:
