So you are going to need to push back into your commercial channel to try get hold of an executable to get it back as I am not sure there is going to be anyway to determine what is going on or to recover it purely through the MBIM interface alone.
So because you have set the unit into a mode where the AT commands are no longer accessible you can no longer send AT commands to either recover the unit or get information about it. You need a windows application that uses MBIM (which is the only interface you have set) to be able to do this, a chicken and egg situation.
What I mean by push back is that you will have bought the unit from someone, assuming they are an official distributor, they will have a support path into Sierra to see if there is such an application to recover the unit.
Looked like the module was in Low Power Mode. Check to see if there is a Wireless Switch either on the side of your laptop or a combination of Fn with Function keys.
@mlw thank you so much! I will try it when i get home
@tomato I have tried that, however, it used to work when I cycled airplane mode. Now it won’t do anything, just says its switched off. Is there a way to force low power mode off?
Do you have the driver package from your laptop vendor? You can add “USBCOMP=8” in configuration.ini file without quotation marks and re-install the driver package again. That will enable the AT port then you can issue AT+CFUN=1 to get out of LPM.
Awesome I just used a random vendor of the device, downloaded the drivers from GETAC and changed the configuration.ini file, works like a charm thank you @tomato@mlw
So there is a W_DISABLE line on the system connector and you have this held so that it turns the radio off, you cannot override this in firmware you have to change the hardware state of the line.
