Anybody could help me with this, i’m new to this Q24 series gsm modules.I’m on a project using the Q24 classic, it’s somewhat similar to a vending machine.
there’s coin and bill reader, a display ,a keypad and the transaction will be send over the GSM network…
My questions are:
- do i need another MCU to handle the process?
- how could i employ a SIM select option for me to switch to different GSM network provider?
- does the SMS that the module will send is authenticated by the GSM network provider?
Your reply would be a great help.
