First, the ATmega48V only has one UART. This is connected to the GPS module at 9600, 8N1. The connection to the GSM M-590 module is only 2400 bps, and slow enough for a bitbanged UART.

The module, or shield, was developed in conjunction with Telefónica’s Physical Internet Laboratory and is available to purchase. The open-source GSM Shield comes with a Telefónica SIM card ready to be ...

T.K. Hareendran introduces us to the SIM800L.Intro to the SIM800L If you are looking for a compact GSM/GPRS module, you can get the SIM800L from most eBay traders. It is not the most judicious choice, ...

Arduino devices have had the option of a GSM linkup for awhile, but getting that cellular link to truly strut its stuff hasn't always been easy, even for those of us who'd be inclined to program ...

The GSM Shield also includes a Telefonica SIM card that includes a worldwide data tariff which can be used anywhere there is a cellular signal. Features include the ability to have the Arduino ...

The Arduino MKR series of boards - aimed at the IoT, for example the MKR FOX 1200 supporting SigFox - has two new members, aimed at LoRa and GSM connectivity. Welcome the Arduino MKR WAN 1300 (LoRa) ...
