I just purchased one of your A9 GSM/GPRS Modules and I am having some trouble connecting it up with my arduino uno.
No AT commands are working at the moment. I am using a Telstra Prepaid simcard.
I just wanted to confirm the baud rate and if 3g is compatible with this GSM module?
Also, if there is something that I am maybe doing wrong for the module to not work?
Thank you for your help
Unfortunately, it’s not 3G compatible, we’re currently working through the issues on the A9G modules, as they are based on 2G which doesn’t exist in most of Australia or NZ anymore. If you’d like to send us an email by replying to your order confirmation email we’ll see what we can do to sort out an appropriate replacement product or help you get this one setup correctly from there. Have a great day!
