Hi Guys

I have a board with a SIM7682 on board plus a PIC18F46K80 connected via UART and would like to be able to do certain read and write to the PIC over the internet and not sure how to go about it. If anyone can point me in the write direction it would be much appreciated.

Hi

I haven't used the SIM7682 module but I have used the SIM800L and variants which are 2G modules.

To do anything over UART you need to be familiar with "AT" commands and a search for "SIM7682 AT Commands" should prove useful.

You would initialise a UART on your PIC then issue the appropriate commands to setup your SIM7682 module. Once the module is initialised you can then do many thinngs with the AT commands such as make a call, send/receive SMS messages and send data.

The AT commands for the SIM7682 are slightly different to the SIM800L but generally speaking the process is pretty similar.

The "old" forum has many posts regarding the use of the SIM800 to send data and this link might be helpful

It refers to updating ThingSpeak with a value but does include details on how to set up the SIM800 using AT. I tend to first connect the module to my laptop and use a terminal program to establish what commands I need to use, then I would incorporate into my chart.
