Raspberry Pi port LoRaMAC in C / LoRaWAN in C http://www.research.ibm.com/labs/zurich/ics/lrsc/lmic.html
This is a port of IBM's LMIC 1.5 to the Raspberry Pi using the wiringPi library for GPIO/SPI. It is adapted for TTN (http://thethingsnetwork.org).
It has been tested with an HopeRF RFM95W chip, but should also work with a SX1272 or SX1276.
Some of the changes were taken from or inspired by the arduino-lmic-v1.5 port of tftelkamp (https://github.com/tftelkamp/arduino-lmic-v1.5.git)
The connections of the pins are defined in the main programs in the examples directory. Standard connections are: WiringPi 6 == nss
not connected == rxtx: not used for RFM95
WiringPi 0 == reset (needed for RFM92/RFM95)
WiringPi 7,4,5 == dio0, dio1, dio2
WiringPi 12 == MOSI
WiringPi 13 == MISO
WiringPi 14 == SCK
GND == GND
3.3V == +3.3V
The only examples currently implemented are hello (which does nothing) and thethingsnetwork-send-v1 which sends test strings to the TTN network (if a gateway is in reach). Do not forget to put your own device number in thethingsnetwork-send-v1.cpp!!
