I am writing an application for my FMC001 device, and have the stock firmware installed in the device via configurator. However, my application wants to talk to the device with a serial application, but it seems that the device doesnt respond to basic AT commands like ATI or AT+CPING , etc.
I totally understand that these command must not have been implemented in the modem, so my question is :
- Where can I get a list of AT supported AT commands for this device or modem ?
- If I want to modify the firmware of the modem, then is there an SDK or a toolkit that allows that, or we just take the firmware from teltonika with no way to modify it ?
- The existing firmware .e.xim which I downloaded for my device is a wierd format and I dont know any tools available that can generate such firmware for my code, if there is one then where can i find it.
I am stuck with this for quite some time and seem to find no information.
Thank you.
