I have a 25 systems with a G120 module… Sometimes they work smooth for days. But there are moments they behave weird… Cant join WiFi AP, problems using sockets to connect to a server… When this behavior shows up the only way to get rid of it is to flash the firmware and the application… Its clear to me that something must has changed in flash firmware and/or settings for what ever reason.
GHI can you supply some code to do a check on firmware changes. I was thinking of some kind of code that calculate a checksum at the startup of main, store it on SD card and every time the system is started doing a compare
Are there know issues with the modules from the first production run?
