SX 10: RX from all nodes

This example shows how to configure the SX1272 module in LoRa mode and then receive packets from any node. This code works as a network sniffer because independently the packet is sent to, this module gets it and shows it.

Required Materials

1 x Waspmote PRO 1 x Battery 1 x MiniUSB wire 1 x SX1272 module (LoRa) 1 x At least one sender to check this receiving code

Notes

The SX1272 module is provided with a special 4.5 dBi antenna, which enables maximum range. The only exception is Smart Parking; in this case the antenna is smaller, 0 dBi, to fit inside the enclosure.
It is not recommended to work without an antenna screwed to the module. The module could be damaged due to RF reflections.
The SX1272 module can only be used in special Waspmote units which have been modified to drive the SPI pins to SOCKET0. (only SOCKET0 is available for SX1272)
This module does not save the configuration. So, the network settings as the mode or the channel MUST be configured every time it is switched on.
This example can be executed in Waspmote v12 and Waspmote v15
