I have a ZBT 628 router the OpenWRT firmware and the EC25 modem. How do I access the modem to do AT command?

Dear Mjamm2000,
Thanks for your inquiry in Quectel forum.
If you want to access the EC25 module to do AT command, you can try to use UART port or USB port. If you want to use USB port, please install the USB driver firstly, you can refer to the following document. Thanks!

I guess, the router is ZBT WE826, but that does not matter. Just install any terminal like picocom for example.
With this OpenWrt based firmware it is possible to access AT commands right from the web GUI.

You can install minicom to send AT commands EC25 will be controlled by ttyUSB2 port.
