Hi,
Besides sending simple SMS, what other methods are available to send data from
modem terminal to modem terminal? I am using wireless methods, and
am constrained by sms character limits in the amount of characters I can send.
Can anyone suggest what other methods are available?
Sorry. As I do not know other methods for direct data transfer from modem to modem.
Thanks,
Nick
Hello,
You could use Internet services. The functionality may depend on the module that you are using.
You can start a socket lisner on the module to listen for incomming TCP socket connections or use UDP datagrams in the similar way. It is possible with AT commands - there are examples in the AT Commands specification document. To receive connections you need a public IP address, so you also need an agreement with your network provider. Or you'd need a solution with an external server, some cloud solution etc. If you are using Java MIDlet you can do the same with Java API.
If the module is controlled by some microcontroller you can also use the module as a modem if your device can handle it's own protocol stack (for instance it's a device with Linux OS).
