Re: How to establish M2M communication with gammu?

Hi Gilberto,

I've asked for M2M solutions to Portugal operators. Only Vodafone 
answered and basically they just sell a SIM card which allows data traffic.

Using a card like this in a SIM800L module, I can send/receive SMS and 
also run USSD commands.

But what I need is to communicate between two machines using the same 
hardware. If I use SMS, it is too costly. It costs around 0.085 EUR. 
0.085 EUR may seem low cost, but multiplied by thousands it's expensive.

So, there must be a way to connect M2M through Internet, i.e. GPRS? Am I 
right? Does gammu allow this?

I can get HTTP pages with AT commands. Does gammu allow an abstraction 
layer on top of AT commands to get HTTP pages?

Thanks.
