Send (GET & SET) RAW RDM commands to fixtures (command line / Bash)

[Rob Walker]

What is the best way to send/receive RAW RDM commands to the connected fixtures inside OLA ?

I can use the OLA RDM - to discover the fixtures and see the RDM parameters etc, but i want to do this from the command line...

I need to send manufacturer unique PIDS for new features, and need OLA as a test engine.

I was looking for documentation, but hard to find...

once i can address a fixture and send a GET, I can then script (simple Bash or Python)

appreciate a quick ping back.

anyone ?

I see rdm-get, and can easily use to find values:

ola_rdm_get  --universe 1 --uid 0xxx:abcdefgh supported_parameters
ola_rdm_get  --universe 1 --uid 0xxx:abcdefgh device_info

ola_rdm_get  --universe 1 --uid 0xxx:abcdefgh dmx_start_address

how do i similarly use rdm-set  ?

with new 'manufacturer' parameters ?

Hi, have you tested ola_rdm_set --help ?

https://wiki.openlighting.org/index.php/RDM_with_OLA

ola_rdm_set

https://wiki.openlighting.org/index.php/RDM_with_OLA

states:

“The dummy devices also support one manufacturer specific PID, to allow you to experiment with those features, which returns the current OLA version.”

 

The open lighting PIDS are listed here:

https://wiki.openlighting.org/index.php/Open_Lighting_PIDs

The index break-down is here:

http://rdm.openlighting.org/pid/manufacturer?manufacturer=31344

 

so we see 7 different pre-assigned PIDS

1. How do we set a new ‘manufacturer specific PID’ ? I don’t see a command line option
2. A full list of PIDs are displayed with ‘ola_rdm_set -l’, but
1. there are no ‘manufacturer specific PID’
2. even the OLA defined example, 8006 = PIXEL_COUNT is not displayed here, so how is it used ?

 

what I would like is simply to state in the CLI, for example PID=8007, and DATA=’xyz’

As far as I remember, to use old_rdm_set with manufacturer pids you'll
need to define them in a file like
https://github.com/OpenLightingProject/ola/blob/master/data/rdm/manufacturer_pids.proto
and then pass --pid-location pointing to the directory
