`read`

go-udap read <mac> [--all|-a] [--timeout DURATION]

What it does

Reads every recognised NVRAM parameter (the 26 in udap.Parameters) from the device and prints them as param=value lines, sorted by parameter name.

By default, factory-default values are filtered out so the output round-trips cleanly through set --config FILE. Pass --all (or -a) to include factory defaults and unrecognised offset_NNN entries.

Output

param=value lines, one per parameter, sorted by name. Suitable for redirection to a .conf file.

Flags

Flag	Default	Description
`--all`, `-a`	off	Include factory-default values and unknown-offset entries
`--timeout DURATION`	`5s`	Operation timeout

Exit codes

0 — success
1 — invalid MAC argument
2 — device not found, or transport error

Examples

# Back up a device's non-default settings
go-udap read 00:04:20:16:06:02 > backup.conf

# Restore later
go-udap set 00:04:20:16:06:02 --config backup.conf --reboot
