In simpler terms, combining Raspberry Pi with SIM800C allows you to create projects that require wireless communication capabilities.

Communication Features of Raspberry Pi Sim800c

Raspberry Pi PCB

The Raspberry Pi sim800c features some communication capabilities. These features enable the transfer to and reception of data from similar devices. The following are three of these communication features:

1. GPRS (General Packet Radio Service):

The SIM800C module, in conjunction with Raspberry Pi, enables GPRS (General Packet Radio Service) communication. GPRS is a packet-switched data service that allows for the transmission and reception of data via a mobile network. In addition, it permits the transmission of data packets between devices and the internet, making it perfect for Internet of Things (IoT) applications with low data rates.

You can wirelessly transmit and receive data via a mobile network using GPRS without requiring a Wi-Fi or Ethernet connection. This feature makes it a practical alternative for remote monitoring and control applications in which a wired connection may not be available or suitable. For instance, you can use Raspberry Pi with SIM800C to remotely monitor the temperature and humidity of a greenhouse and receive warnings if you exceed some specified criteria.

Moreover, GPRS permits the usage of the MQTT (Message Queuing Telemetry Transport) protocol, a lightweight messaging protocol built for IoT devices. MQTT allows you to transmit and receive data messages over GPRS, enabling you to construct IoT applications that interface with other devices and cloud services.

2. GSM (Global System for Mobile Communications):

SIM800C also has GSM (Global System for Mobile Communications) connectivity capabilities, allowing you to send and receive SMS messages and make and receive phone calls. This capability is handy for constructing mobile communication devices or adding communication features to existing projects.

For instance, you may use Raspberry Pi and SIM800C to create a mobile weather station to make and receive phone calls and send SMS notifications when the weather worsens. In addition, you can use it to develop a GPS-tracking gadget that delivers location updates via SMS and a remote-control system that lets you operate devices via the phone.

GSM communication also enables using USSD codes, employed by mobile network carriers, to deliver services such as balance inquiries, account management, and top-up services. In addition, with USSD, it is possible to design mobile applications that interface with mobile network services, enabling the development of novel mobile applications.

3. Bluetooth:

While the SIM800C module lacks Bluetooth capabilities, the Raspberry Pi has Bluetooth capabilities that can enable wireless communication with other devices. Bluetooth is a technology for short-range wireless communication that permits devices to exchange data across short distances.

Using Bluetooth, you can design applications that connect with other Bluetooth-enabled devices, such as smartphones, tablets, and Sensors. For instance, you may use Raspberry Pi with a Bluetooth sensor to monitor the temperature and humidity of a room and then transmit the data to a smartphone app for analysis and visualization.

Bluetooth also permits the usage of the BLE (Bluetooth Low Energy) protocol, intended for low-power IoT devices. Using BLE, it is possible to develop IoT applications tailored for battery-operated devices that consume minimal power. For instance, you can create a secure remote access system for your house or workplace using Raspberry Pi and a BLE-enabled smart lock.
