Hi, I am using Q2687 module for remote reading of some PLC data in field.
By now I’ve succeeded to make GPRS TCP socket connection with the devices and read all the data (well not 100% to be ohnest )
But by the time customers ask for modifications and more data, while it’s so hard to reprogram all the modules in field. Can we use the GPRS connection for reprogramming modules?
If this is possible so where to start?
