Resin.io The Things Network Gateway based on Raspberry Pi

This uses a fork of the Single Channel LoRaWAN Gateway on a Raspberry Pi as described by Dragino on resin.io.

With resin.io you can easily manage multiple gateways on multiple devices remotely and use environment variables (see table at the end of the page) to control each of the device parameters.

Hardware

It uses a Raspberry Pi Model B+ V1.2 and

• a Modtronix inAir9 SX1276 LoRa Module

OR

• a Dragino Shield v.1.3.

Default pin mapping:

Dragino LoRa v 1.3	inAir9	Raspberry Pi	WiringPi
3.3V	3.3V	pin #1
ICSP GND	GND	pin #6
ICSP MISO	MISO	pin #21
ICSP MOSI	MOSI	pin #19
ICSP SCK	SCK	pin #23
Pin 10	NSS	pin #22	6
DIO0	DIO0	pin #7	7
RESET	RST	pin #11	0

Environment variables for resin.io

Variable name	Value	More info
DIO_PIN	7	Optional. Defaults to 7 (WiringPi pin).
RST_PIN	0	Optional. Defaults to 0 (WiringPi pin).
SS_PIN	6	Optional. Defaults to 6 (WiringPi pin).
EMAIL_ADDRESS	you@domain.com	Optional, empty by default.
FREQUENCY	Depends on your location and chip	Optional. In Hz. Defaults to 868100000
HOSTS	Depends on your location	Optional
LATITUDE	Your latitude	Optional. Float. Defaults to 0.0
LONGITUDE	Your longitude	Optional. Float. Defaults to 0.0
ALTITUDE	Your altitude	Optional. Integer. Defaults to 0

Example

Client

You should be able to get most of the code from the instructables page (see link in the intro), however I needed to add

#define CFG_eu868 0
#define CFG_us915 1

and

LMIC_setupChannel(0, 916800000, DR_RANGE_MAP(DR_SF12, DR_SF7),  BAND_CENTI);

to my sketch to connect to it. You can then read the results from the TTN website (https://thethingsnetwork.org/api/v0/nodes/<DEVICEID>/).
