I purchased this board and am not able to get GSM working. Shield Board
I’m hoping someone has already figured this board out and can help, I’m becoming convinced this board is very non-standard.
Unfortunately it does not come with any documentation, pin usage, libraries, or example code.
I have been successful getting GPS results that are correct when checked on Google maps.
Now I need to send text messages, and eventually emails. But no matter what I try it doesn’t seem like any of the commands are even making it to the board, many attempts just hang up on the first command.
I have worn Google out searching every which way I can think of to find information (including this forum)
I have found and tried several different libraries including the AiThinker_A7-master library from GIThub.
I’ve tried dozens of different code examples, all different approaches, some with libraries some plain code.
Every attempt seems to behave the same way.
I have not been able to find a definitive pin usage definition, some say 0-1, many say 7-8, there have even been a couple different ones I’ve come across. some say 0-1/7-8 for software/hardware serial, some do not
I’ve extensively tried the official included Arduino <GSM.h> library but it has compiler problems as discussed in these forums. My IDE version is 1.8.5 and it sounds like that may be a problem for this library.
I have also tried a separate power supply in addition to the IDE’s USB connection, as a youtube video I watched said this was critical.
I would post code, but I’ve tried so many different sketches (as found, and with attempts to modify) I’m thinking it’s not all a code problem.
Any help will be greatly appreciated
