![]() ![]() As explained on this page, the PL-2303 in the modem uses non-default USB PID make sure to grab the latest version of my library, which transparently supports both PIDs. The modem is built around BenQ M23 GSM/GPRS Wireless module and uses Prolific PL-2303 USB-to-serial converter. It supports a standard subset of GSM commands as well as some proprietary ones. What is left makes inexpensive (~$25), lightweight (25 grams) and compact (see title picture) GSM/GPRS module to use in DIY projects. USB Tri-band GPRS Modem from DealExtreme is just an ordinary GSM cell phone minus keyboard, display, battery, and built-in microphone/speaker. Today I’m going to talk about one such piece of hardware which can be connected to Arduino board using USB Host Shield. For many of these tasks any old phone works quite well, however, there are times when a specialized piece of hardware is desired. Using standard GSM AT commands, a program running on Arduino can place and take calls, send and receive SMS, shoot pictures, access the Internet while monitoring phone’s battery level, signal strength and connection status. Some time ago I started writing about connecting Arduino to cellular network. ![]()
