Jun 15, 2016 · GSM Modem interfacing with arduino. Connecting GSM modem with arduino is very simple just connect RX Line of Arduino to TX Line of GSM Modem and vice versa TX of arduino to Rx of GSM modem. Make sure use TTL RX, TX lines of GSM modem. Give 12V 2Amp power supply to GSM modem, Use of less current power supply can cause reset problem in GSM modem ... This post is a complete guide to the SIM900 GSM GPRS Shield with the Arduino. Learn how to sends SMS, receive SMS, make and receive phone calls with Arduino. We provide schematics on how to wire the shield to the Arduino, and all the sketches needed to send and receive SMS, as well as to make and receive phone calls. GSM module interfacing with Arduino: Send and receive SMS Interfacing GSM SIM900A with Arduino : SIM900A is an ultra-compact and reliable wireless module. The SIM900A is a complete Dual-band GSM/GPRS solution in a SMT module which can be embedded in the customer applications. The main components of the Cellular Shield are a 60-pin SM5100B connector, a SIM card socket, and an SPX29302 voltage regulator configured to regulate the Arduino's raw voltage to 3.8V. The board's red LED indicates power. The Arduino's reset button is also brought out on the shield. The ancient 2G cellular network is now dying. New and better LTE technologies are being used instead. LTE Cat M1/Cat NB1(NB-IoT) is the latest way of the cellular communication. This LTE shield for your Arduino lets you connect the Arduino to this new cellular networks thanks to Quectel BG96 LTE module on it.
