LoRa Device Tutorial

When setting up a LoRa client device, you need to do five main steps:

1. Setup the firmware on the specific device and get the LoRa DevID (specific to device, see below)
2. Create a description for the device in OpenChirp (described in Device Tutorial)
3. Add the LoraWAN service in OpenChirp and input the DevID
4. Add a decoder service (Byte Translator or Easybits)
5. Add a TimeSeries datastore service

Step 1: Load firmware onto your device

The most important aspect of the firmware on your device will be retrieving its DevID and setting an appropriate AppEUI and AppKey. The DevID is used to tell the network to look for your device. The AppEUI and AppKey are used for the network to correctly authenticate to your device. In OpenChirp you can set your own AppEUI and AppKey when linking in your device. The DevID comes from the device itself.

A typical AppEUI is a 16 digit hex number like 0000000000000000 and typical AppKey is a 24 digit random hex string like 11B0282A189465B0B4D2D8C7FA38548C. Both can be shared across all of your devices, but the DevID is unique for each device.

Though the firmware is specific to your device, here are some common devices with examples that work with OpenChirp:

• PyCom LoPy
• LoRaBUG
• MultiTech Mdot

Step 2: Create a device in OpenChirp

Creating a LoRa client device is the same as creating any other OpenChirp device. Please follow the Device Tutorial.

Step 3: Adding the LoraWAN service

Once you have a device in hand with its DevID and you have created an OpenChirp Device with a known end point, you need to add the LoRaWAN service.

Go to your device and click on the "Services" tab at the top. Enter the parameters as shown below:
