Command-line interface only
The instructions below use the command-line interface (CLI).
You can create a device template from an existing device or extend an existing device template. You can also create a new template from scratch.
We define some user parameters that will be used below:
APP_ID="app1"
DEVICE_ID="dev1"
FREQUENCY_PLAN="EU_863_870"
LORAWAN_VERSION="1.0.3"
LORAWAN_PHY_VERSION="1.0.3-a"
Make sure to modify these according to your setup.
Create from existing device
You can use the end-device template create command to create a template from an existing device.
By default, end-device template create strips the device’s application ID, device ID, JoinEUI, DevEUI and server addresses to create a generic template.
You can include the end device identifiers by passing the concerning flags: --application-id, --device-id, --join-eui and --dev-eui.
Pipe the output from getting a device to create a template, for example:
ttn-lw-cli end-devices get $APP_ID $DEVICE_ID \
--lorawan-version $LORAWAN_VERSION \
--lorawan-phy-version $LORAWAN_PHY_VERSION \
| ttn-lw-cli end-devices template create > template.json
Output
{
"end_device": {
"ids": {
"application_ids": {
}
},
"created_at": "0001-01-01T00:00:00Z",
"updated_at": "0001-01-01T00:00:00Z",
"lorawan_version": "1.0.3",
"lorawan_phy_version": "1.0.3-a"
},
"field_mask": {
"paths": [
"lorawan_version",
"lorawan_phy_version"
]
}
}
Extend existing template
Use the end-device template extend command to extend a template:
cat template.json \
| ttn-lw-cli end-devices template extend \
--frequency-plan-id $FREQUENCY_PLAN
Output
{
"end_device": {
"ids": {
"application_ids": {
}
},
"created_at": "0001-01-01T00:00:00Z",
"updated_at": "0001-01-01T00:00:00Z",
"attributes": {
},
"lorawan_version": "1.0.3",
"lorawan_phy_version": "1.0.3-a",
"frequency_plan_id": "EU_863_870"
},
"field_mask": {
"paths": [
"lorawan_phy_version",
"frequency_plan_id",
"lorawan_version"
]
}
}
See ttn-lw-cli end-devices template extend --help for all the fields that can be set.
Create from scratch
The end-device template extend can also be used to create a new template from scratch by simply not piping an existing device as input.
For example, create a new template from scratch:
ttn-lw-cli end-devices template extend \
--lorawan-version $LORAWAN_VERSION \
--lorawan-phy-version $LORAWAN_PHY_VERSION \
--frequency-plan-id $FREQUENCY_PLAN
Output
{
"end_device": {
"ids": {
"application_ids": {
}
},
"created_at": "0001-01-01T00:00:00Z",
"updated_at": "0001-01-01T00:00:00Z",
"attributes": {
},
"lorawan_version": "1.0.3",
"lorawan_phy_version": "1.0.3-a",
"frequency_plan_id": "EU_863_870"
},
"field_mask": {
"paths": [
"frequency_plan_id",
"lorawan_phy_version",
"lorawan_version"
]
}
}
