Hi everyone,
I’m looking to use a GM862 as a GSM link for an Arduino-based device. I would like to be able to perform OTA or near OTA updates of not just the GM862, but the Arduino in the field.
I have hardware jumpers on the board to reset the Arduino so it can be pulled into Bootloader mode, and another jumper that will pull the DTR pin low and execute a Python script on the board. I would set both jumpers and unplug the device to get it to reboot with the Python script running and the Arduino in “learn” mode.
I did a search and didn’t see anything that helpful on this front. Has it been done? My biggest concern is getting the data file onto the GM862 to be loaded. I can preload a .py file to read the contents of a text file, but how do I read from the incoming data stream to a file on the GM862? Any help would be greatly appreciated.
Thank you!
