ST / Mbed 2 deprecated HelloWorld_IDS01A4

HelloWorld_IDS01A4 mbed application for Spirit1 P2P demo.

Dependencies:   mbed

Fork of HelloWorld_IDS01A5_Program by rosarium pila

mbed 2.0 (a.k.a classic) HelloWorld example for Spirit1 to transfer data from one node to another.
To send the predefined data packet from the sender to the receiver, user needs to press User Button on the board. The LED on the receiver expansion board will toggle on reception of data successfully.
Data packets sent and received can be seen on USB serial terminal.

EVALUATION BOARDS RF FREQUENCY DESCRIPTION :
X-NUCLEO-IDS01A4 868 MHz 868 MHz RF expansion board based on SPIRIT1
