This article illustrates some basic ideas for how to build remote control applications using SMS or simple toll free GSM calls using the BEE Board and some Daisy modules.
The key module to implement these applications is the DAISY-13 which contains a quad band GSM modem, a SIM holder and a GSM antenna and talks with the BEE Board through a software serial port on the W4 connector.
This module extends the BEE Board capabilities to:
All the application examples listed below are fully working and can be made with a basic kit called BEEKIT-2 and one or more other Daisy interfaces. The code provided is fully open source and can be integrated into your own applications under GPL licence terms.
This application receives a telephone call, checks if the incoming number is stored on the SIM card phonebook, if yes turns on a relay for 1 second then hangs up on the incoming call. Because there is no need to answer the call but only check caller ID, there is no charge for the caller.
The main field application of this example could be a remote controller to open a gate used by more than one person. In this way it's possible to save the cost of one radio controller per person by just adding the mobile phone number of those who are enabled to ring and open the gate.
The hardware required is:
Code for Arduino IDE 23 or less TollFreeRelay.pde
Code for Arduino IDE 1.0 or greater TollFreeRelay.ino
This examples illustrates how to make a SMS remote control to set up to 4 output line.
The hardware required is:
Code for Arduino IDE 23 or less SMS4Relay.pde
Code for Arduino IDE 1.0 or greater SMS4Relay.ino
Build a push button panel that shoots an SMS to different mobile number with different message text.
The hardware required is:
Code for Arduino IDE 23 or less SMSshooter.pde
Code for Arduino IDE 1.0 or greater SMSshooter.ino

The Teltonika module is default configured at 115200 baud and Flow control enabled. To work with the Bee in Software Serial mode, it is necessary to change these settings:
To change these settings you can proceed in this way:
When the Tx LED stops flashing, you can disconnect Daisy-13 from the W1. Now the Teltonika modem is ready to work with the Bee to W4 port.
