When a SpringCard device is found "in the nearby" by the Begin Lookup / End Lookup method, a JSON FOUND_DEVICE object is created and populated that contains the (few) technical data publicly exposed by the device.

This object is consistent with the DEVICE object, yet a lot of data are still missing at this step because the service does not have a full access to the device itself yet. Use the Network Setup route to attach the computer to the device.

Object definition

Field name Type Status Description Condition
"TemporaryId" string always The TemporaryId of the (available) device. Use this as {$id} in all /setup/{$id} requests
"AssociatedDeviceId" string option If the found device is already installed, its current DeviceId Device already installed
"Name" string always Name of the device, collected from the device's meta-data
"Channel" string always Communication channel: ble or network
"PnpId" string option Technical identifier of the device, in the form ssvvvvpppprrrr where
-ss is the VendorID source (02for USB Workgroup),
-vvvvis the VendorID in hex (1C34 for SpringCard),
-pppp is the ProductID in hex,
-rrrr the Release (for instance, 0210 for version "2.10")
"Mode" string always Operating mode of the device: coupler, reader, idle or unknown
"SerialNumber" string option Serial number of the device Not empty
"Version" string option Version of the device (ex: "2.10")
"Firmware" string option Identification of the firmware
"Hardware" string option Identification of the hardware (part number) Not empty
"Characteristics" option option Technical characteristics of the hardware (see Hardware Characteristics) Not empty
"UniqueId" string option Unique Identifier of the device (signature of the hardware)
"ConfigId" string option The GUID of the configuration (signature of the settings) (register 0200) Register set in NVM
"Inventory" string option Inventory number (register 0201) Register set in NVM
"Location" string option Location (register 0202) Register set in NVM
"PhysAddress" string option Physical address of the device, as an hex-string, if this information is available and makes sense.
For a BLE device, this is the BT_ADDR, for a network device, the MAC address.
"Dhcp" boolean option true if the device is configured as DHCP client, false if its network configuration is static Network device
"IpAddress" string option Current IP address of the device Network device
"IpMask" string option Current network mask of the device Network device
"IpGateway" string option Current default gateway of the device Network device
"TcpServerPort" integer option Main TCP server of the device Network device and TCP server profile


The TemporaryId field is really a temporary value. The very same device is likely to get a different TemporaryId the next time it is found by the computer, and a different device may be assigned the same TemporaryId as a previously connected one.

There is no relationship between the TemporaryId and the DeviceID that will be, or is already, assigned to the device.

If you want to identify a particular device, use the SerialNumber or PhysAddress fields.
