Discover Resources
wuji resources lists a device’s readable/writable parameters and subscribable topics:
The command output is the authoritative list. Frequently used parameters:
Read a Parameter
wuji get <path> reads a parameter and decodes it into a typed JSON value automatically:
Use resource paths exactly as wuji resources prints them. Reading a path that doesn’t exist fails with exit code 1, and the error message points to wuji resources for valid paths. When the type is unknown, the default output shows the value as <unrecognized value>, and --json omits the value key.
Write a Parameter
wuji set <path> <value> writes a parameter. The value is JSON, or raw hex bytes with a 0x prefix:
When a host application occupies the device, the CLI runs in read-only access and set is rejected. Release the occupying direct connection and retry.
Notes
- Network parameters such as
ip_address and data_port take effect after a device restart. Not seeing an immediate change in wuji devices is expected
- On Wuji Hand 2, writing
data_port requires recent firmware. Valid ports are 10000–65535, except 50000. An out-of-range value makes set fail and leaves the port unchanged. After a successful write, wuji get data_port returns the new port right away, and the device switches to the new port after a restart
- The message
virtual parameter 'X' currently has no value means the virtual parameter has no default and the stateless CLI doesn’t persist writes — this is expected behavior
