With GSM3 click you can have two of the most used wireless communication protocols in one device — GSM/GPRS and Bluetooth. The click has an onboard 2.4 GHz active antenna, so it is Bluetooth compatible. It carries the SIM800H quad-band GPS/GPRS module from SIMCOM.

GSM3 click is designed to use either 3.3V or 5V power supply and communicates with the target MCU over UART and the following mikroBUS pins: PWM, INT, AN, RST, CS.

Onboard antennas

The click has an SMA antenna connector and an audio input/output pad for connecting a microphone and earphones (which can also be used as an FM antenna).

Quad-band module

SIM800H has world-wide coverage — quad-band frequency: GSM 850, EGSM 900, DCS 1800 and PCS 1900. The module can search four frequency bands automatically.

Low power consumption

Typical power consumption in sleep mode is only 0.7mA. While in sleep mode the SIM800H can still receive SMS.

Key features

  • SIM800H module
    • GPRS data downlink/uplink transfer max: 85.6 kbps

Programming

Code examples that demonstrate the usage of GSM3 click with MikroElektronika hardware, written for mikroC, mikroBasic and mikroPascal for PIC are available on Libstock.

Libstock also hosts an alternative extensive GSM library for a variety of hardware setups and with a detailed user manual.

This code snippet shows the initialization routine for the GSM3 click, when used with AT parser.

 1 void GSM3_init( void )
 2 {
 3     engine_init( gsm_default_handler );
 4     hal_gsm_pwr( 0 );
 5     Delay_ms( 100 );
 6     hal_gsm_pwr( 1 );
 7     Delay_ms( 2000 );
 8     hal_gsm_pwr( 0 );
 9     
10     while( !hal_gsm_stat() );
11     Delay_ms( 10000 );
12     
13     at_cmd( "AT" );
14     at_cmd( "AT+CSCS="GSM"" );
15     at_cmd( "AT+CMGF=1" );
16 }
