Re: How to establish M2M communication with gammu?

Hi,

If I correctly understood your question, you just need two USB dongle or 2 SIM cards that suport data, each operator in Portugal as them, you configure the device to automatically connect to the internet trough 4G that way you will have in each device an IP address which simplifies that rest.

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.
