go-udap info MAC [--timeout DURATION] [--format text|json|csv | --json]

What it doesCopy Anchor Link

Discovers devices on the network, then prints the full metadata block for the one whose MAC matches MAC. Same metadata as discover --info but scoped to one device, and without the get_ip network config (use getip for that).

If the device's discovery reply omits UUID (TLV 0x0d, missing on older firmware), info falls back to get_uuid to populate it.

OutputCopy Anchor Link

The default text format is a multi-line metadata block, one field per line. Empty fields are omitted:

MAC:      00:04:20:16:06:02
IP:       192.168.1.50
Name:     Kitchen
Model:    Squeezebox Receiver
Firmware: 77
HW Rev:   0005
UUID:     deadbeefcafebabe1122334455667788
State:    init

With --json (or -o json), one object: the discover --info object without network. Every field except mac is null when absent:

{"mac":"00:04:20:16:06:02","ip":"192.168.1.50","name":"Kitchen","model":"Squeezebox Receiver","firmware":"77","hardware_rev":"0005","uuid":null,"state":"init"}

With -o csv, a header row and one row. A null value is an empty cell:

mac,ip,name,model,firmware,hardware_rev,uuid,state
00:04:20:16:06:02,192.168.1.50,Kitchen,Squeezebox Receiver,77,0005,,init

The JSON keys and CSV columns are a stable contract: none will be removed or renamed without a major version. New ones may be added. See Output formats.
