u-blox / Mbed 2 deprecated NSDL_Cellular_HelloWorld

cellular port

Dependencies:   Beep C027_Support C12832 LM75B MMA7660 mbed-rtos mbed nsdl_lib

This is a port of the NSDL HelloWorld for cellular.

To run the example you need a C027 and the ARM mbed application shield. The example uses cellular instead of ethernet and takes the true position from the GPS instead of using a fixed position.
