Preliminary

GW-GSM-02

Description

GW-GSM-02 is an IQRF gateway with GSM connectivity intended as an interface between IQRF and GSM/GPRS networks. The user can implement specific functionality by software for internal IQRF TR module.

Main components are 8 b microcontroller, GSM/GPRS transceiver module and IQRF TR module with antennas, FLASH memory and backup accumulator.

GW-GSM-02 can be configured and firmware can be upgraded from PC. Application software for TR module can be uploaded via IQRF IDE4 using the gateway as a programmer.

Key features

• TCP Server mode with public IP address

• SMS alarm feature

• Data logging

• IP filtering

• RTCC (real time clock/calendar)

• Backup accumulator

• Very low power consumption in Sleep mode

• Documented application protocol

• Firmware upgrade via PC software

• Programmable application in internal TR module

Applications

• Remote monitoring and control

• Data acquisition / collection

• Datalogger

• Interface to building / home automation

• Remote control of IQRF network

• Connection of more IQRF networks to one PC

• Access to IQRF network from more locations

Hardware

Power supply

GW-GSM-02 is intended to be supplied by external stabilized 5 V DC connected to micro USB connector.

Accumulator

Backup accumulator is intended especially for short failures of external power supply. It is not removable and enables continuous charging when external power is connected.

Power control button (ON / OFF)

• Short press (< 3s): no effect

• Long press (> 3s): Switching between operational and sleep modes

LED indication

Power LED (red)

Power LED is on when main power is on.

GSM LED (yellow)

• Flashes once per second when GSM module is powered.

• Flashing twice per second when communicating via GSM/GPRS.

Status LED (green)

• Status LED is on when GSM module is establishing connection to network.

• Flashing once per two seconds when GSM is logged in the network.

• Flashing two times per second when an error occurred (missing SIM card etc.)

IQRF LED (red)

This LED is controlled by the TR module, the LEDG output. Functionality is fully under control of user application program. IQRF OS functions dedicated to LEDG can be used. In Demo SW this LED shortly flashes whenever an RF packet is transmitted or received by TR module.

MCU

Microcontroller PIC18F26J50 by Microchip is used.

GSM

M590E dual band wireless module by Neoway is used for GSM/GRPS connectivity.

SIM card

SIM card with activated data services from mobile network operator must be plugged in the SIM connector under the cover. Public IP address is required (see below).

IQRF

TR-54DA wireless transceiver module is used for IQRF connectivity. Antenna is built in TR module.

Flash memory

SST25VF080B 1 MB Flash memory by Microchip/SST is used for gateway configuration and message buffer. Up to 100 000 erase/write cycles (typical) is allowed.
