## Identifiers
|
|
|
|
To connect a Pycom LoRa device (LoPy, LoPy4, FiPy) to Objenious you'll need to provision it. This requires three pieces of information
|
|
|
|
* Device EUI (DevEUI)
|
|
* Application EUI (AppEUI)
|
|
* Application Key (AppKey)
|
|
|
|
### Device EUI
|
|
|
|
This comes from the device itself and can be obtained from `lora.mac()`.
|
|
To obtain the required hexadecimal representation you can run the following code on your LoPy:
|
|
|
|
```python
|
|
from network import LoRa
|
|
import ubinascii
|
|
|
|
lora = LoRa()
|
|
print("DevEUI: %s" % (ubinascii.hexlify(lora.mac()).decode('ascii')))
|
|
```
|
|
|
|
### Application EUI and Application Key
|
|
|
|
Application EUI and Key are two LoRaWAN parameters that should ideally by generated by you, if supplying devices to end customers.
|
|
The Application EUI is a EUI-64 (8 bytes) identifier which should be universally unique - it's usually allocated from a MA-S block purchased from the [IEEE Registration Authority](http://standards.ieee.org/develop/regauth/oui36/index.html).
|
|
The Application Key should be a randomly generated, secure, 128 bit (16 byte) token.
|
|
|
|
For testing purposes we provide a script which generates a random Application EUI from our assignment and a series of Application Keys:
|
|
|
|
[EUI/Key generator for testing](https://github.com/pycom/pycom-scripts/blob/master/lorakeys/generate_keys.py)
|
|
|
|
_(note: the Application EUI produced by this script is not guaranteed to be unique)_
|
|
|
|
To use the script make sure you are using Python 3.6 on your computer and run it (on your computer, _not_ on the Pycom board) as:
|
|
|
|
```bash
|
|
python generate_keys.py 1
|
|
```
|
|
|
|
The output will be similar to:
|
|
|
|
```text
|
|
AppEUI: 70b3d54923e36a89
|
|
AppKeys: 78fe712d96f46784a98b574a8cd616fe
|
|
```
|
|
|
|
If you are registering multiple devices you can generate more Applications Keys by changing `1` to your desired number of devices.
|
|
|
|
## Provisioning
|
|
|
|
Once you have the three identifiers for your device you need to register them on the Objenius portal.
|
|
Follow "Importer des capteurs" under "Statuc do Parc" and select "Provisioning Unitaire":
|
|
|
|
|
|
|
|
Once there give your device a name and enter the DevEUI, AppEUI, and AppKey obtained from the steps above:
