![]() A GPS receiver gives its location by linking to available GPS satellites.Ī GPS receiver can be used to track a location. This is a low-cost GPS receiver that’s commonly used in embedded devices and robotic projects (there are others from several different vendors). By using bidirectional data communication with the modem via a standard UART interface, we were able to make/receive calls and send/receive SMS messages on RPi and a desktop computer.īy using the same UART interface and protocol in this tutorial, we’ll interface a global positioning system (GSP) module with RPi. We employed serial UART communication to “talk” with the SIM900 modem. ![]() ![]() ![]() In the previous tutorial, we learned how to interface a SIM900 GSM-GPRS modem with Raspberry Pi (RPi) and a desktop computer. ![]()
