Device Profile

The Device Profile defines the device capabilities and boot parameters that are needed by ChirpStack Network Server to “connect” with a device.

LoRaWAN^® Backend Interface

The following fields are described by the LoRaWAN Backend Interfaces specification. Fields marked with an X are implemented by ChirpStack Network Server.

• SupportsClassB End-Device supports Class B
• ClassBTimeout Maximum delay for the End-Device to answer a MAC request or a confirmed DL frame (mandatory if class B mode supported)
• PingSlotPeriod Mandatory if class B mode supported
• PingSlotDR Mandatory if class B mode supported
• PingSlotFreq Mandatory if class B mode supported
• SupportsClassC End-Device supports Class C
• ClassCTimeout Maximum delay for the End-Device to answer a MAC request or a confirmed DL frame (mandatory if class C mode supported)
• MACVersion Version of the LoRaWAN supported by the End-Device
• RegParamsRevision Revision of the Regional Parameters document supported by the End-Device
• SupportsJoin End-Device supports Join (OTAA) or not (ABP)
• RXDelay1 Class A RX1 delay (mandatory for ABP)
• RXDROffset1 RX1 data rate offset (mandatory for ABP)
• RXDataRate2 RX2 data rate (mandatory for ABP)
• RXFreq2 RX2 channel frequency (mandatory for ABP)
• FactoryPresetFreqs List of factory-preset frequencies (mandatory for ABP)
• MaxEIRP Maximum EIRP supported by the End-Device
• MaxDutyCycle Maximum duty cycle supported by the End-Device
• RFRegion RF region name (automatically set by ChirpStack Network Server)
• Supports32bitFCnt End-Device uses 32bit FCnt (mandatory for LoRaWAN 1.0 End-Device) (always set to true)

Geolocation buffer

The following extra fields can be used to configure the geolocation buffer:

• GeolocBufferTTL Maximum TTL for items in the geolocation buffer.
• GeolocMinBufferSize Minimum required buffer size before using geolocation.
