AT Command Manual for EM20-G and RM500-Q

Hello!

Does anyone know where I can find the AT Commands for those two modems (EM20-G and RM500Q-GL) or the commands that work with them?

Hi,
Thanks for your query in Quectel forums.
EM20-G has no archived AT manual for the time being. I will send you the AT command manual of RM500Q first.
thanks

Thank you!

Two more questions:

I cannot find the command to change the modem’s protocol. It should be something like,‘AT+QCFG=“usbnet”,2’. I don’t see it anywhere. Is the manual not complete with all the commands and is there another list of commands or am I just missing the obvious?
Is it necessary to continually update the firmware on the modem manually, or does this happen automatically? If manual, where do I find the firmware updates?

Thank you!

Hi,
Thanks for your query in Quectel forums.
AT+QCFG=“usbnet”,2" Although this command is supported, this command is not included in the official AT command document for the time being, and it will not affect your use of this command.

thanks.
