In order to use The Things Network (TTN) you should navigate to their website and create/register an account. Enter a username and an email address to verify with their platform.
Once an account has been registered, you can register your Pycom module as either a node or a nano-gateway. The steps below will detail how to do this.
In order to register your device to connect to the things network, you must first create an application for these devices to belong to. This way the Network will know where to send the devices data to.
Applications tab at the top of the TTN console, will bring up
a screen for registering applications. Click register and a new page, similar
to the one below, will open.
Enter a unique
Application ID as well as a Description & Handler
Now the Pycom module nodes can be registered to send data up to the new Application.
To connect nodes to a things network gateway, devices need to be added to the
application. To do this, navigate to the
Devices tab on the
home page and click the
Register Device button.
Register Device panel, complete the forms for the
Device ID and
Device EUI. The
Device ID is user specified and is unique to the
device in this application. The
Device EUI should be a globaly unique
identifier for the device. You can run the following on you Pycom module to
retrieve its EUI.
from network import LoRa import binascii lora = LoRa() print("DevEUI: %s" % (binascii.hexlify(lora.mac()).decode('ascii')))
Once the device has been added, change the
Activation Method between
ABP depending on user preference. This option can be found
under the Settings tab.
You can also setup your Pycom module to act as a gateway with The Things Network. The code required to do this can be found here.
Inside the TTN Console, there are two options,
gateways and then click on
register gateway. This
will allow for the set up and registration of a new nano-gateway.
On the Register Gateway page, you will need to set the following settings:
These are unique to each gateway, location and country specific frequency. Please verify that correct settings are selected otherwise the gateway will not connect to TTN.
You need to tick the "I'm using the legacy packet forwarder" to enable the right settings. This is because the Nano-Gateway uses the 'de facto' standard Semtech UDP protocol.
|Gateway EUI||User Defined (must match config.py)|
|Frequency Plan||Select Country (e.g. EU - 868 MHz)|
|Antenna Placement||Indoor or Outdoor|
Most LoRaWAN network servers expect a Gateway ID in the form of a unique 64-bit hexadecimal number (called a EUI-64). The recommended practice is to produce this ID from your board by expanding the WiFi MAC address (a 48-bit number, called MAC-48). You can obtain that by running this code prior to configuration:
from network import WLAN import binascii wl = WLAN() binascii.hexlify(wl.mac())[:6] + 'FFFE' + binascii.hexlify(wl.mac())[6:]
Once these settings have been applied, click
Register Gateway. A Gateway
Overview page will appear, with the configuration settings showing. Next click
Gateway Settings and configure the Router address to match that of
the gateway (default: router.eu.thethings.network).
Gateway should now be configured.
