Imp004 + gsm module

hi, currently im looking to implement gsm module on imp004. but im not sure if i’ll be able to update firmware via uart. is this possible?

You can certainly talk to a GSM module with imp004m, at an application level - but all comms, squirrel firmware updates etc can only go over a system-supported network interface. On imp004m, that means wifi.

You should look at imp006, which supports cellular (almost any Quectel module) and a couple of different WiFi/BLE modules.

thank you for answering @hugo .
