Good day to all…
I just want to ask, is it possible to use two arduino board with only one GSM module? Please, share if you have any link that I can be guided.
Because I’m currently working with Arduino, GSM SIM900 and VB.net. The application that I made in VB.net was not able to receive while sending SMS. The arduino is able to receive sms but it was mixing with SMS that currently sending. So VB.net can only get the message sent and can’t receive the SMS.
Anyone who can help me? Do you know other way to send and receive SMS at the same time?
Thank you in advance.
