Quicksand micro-electronics / Mbed 2 deprecated HelloWorld - QW Development kit

A first code example to get you started with the QW (GPS) Shield for SIGFOX development. It provides a serial connection to the modem over usb and transmits a SIGFOX message upon a button press.

Dependencies:   mbed QW_Sensors

HelloWorld QW Development kit

Preloaded code example

The QW development kits ship with this code example. This example allows you to talk straight to the TD1208 modem when using a virtual com port (note: local echo is off). This code-example also sends a SIGFOX message whenever you press a button. The message contains the button number and the measured environment temperature. The first byte is always 0x01.
