OLA ArtNet plugin not sending broadcasts

[Vsevolod Ryabokon]

Hi! Trying to use OLA with ArtNet device SJ-DMX-E16. As i understand, olad server must discover Artnet devices while sending broadcasts on udp port 6454. But i do not see any broadcast packets on udp port 6454. Only i sow these packages after i changed my artnet config and set net = 2 and subnet=2, but after i restarted the olad this broadcasting stops. 

I used it on raspbian with ola 0.9.1 (from apt-get install). 

My ip: 192.168.0.185/24

ola_dev_info : 

Device 1: ArtNet [192.168.0.185]

  port 0, IN, priority 100, RDM supported

  port 1, IN, priority 100, RDM supported

  port 2, IN, priority 100, RDM supported

  port 3, IN, priority 100, RDM supported

  port 0, OUT, RDM supported

  port 1, OUT, RDM supported

  port 2, OUT, RDM supported

  port 3, OUT, RDM supported

Device 2: Dummy Device

  port 0, OUT Dummy Port, RDM supported

My artnet config: 

always_broadcast = true

enabled = true

ip = 192.168.0.185

long_name = OLA - ArtNet node

net = 0

output_ports = 4

short_name = OLA - ArtNet node

subnet = 0

use_limited_broadcast = false

use_loopback = false

my tcpdump command: tcpdump -i eth0 port 6454 -nn.

my olad command: sudo -u olad olad  -c /etc/ola -l 4, 

olad output:

PLease, help me with connecting external Artnet device. Thank you!

You don't appear to have patched the ArtNet universe within OLA, either via ola_patch or the web UI.

Do you mean the packets only ever appear when you change the device's net and subnet, or OLAs? The device is supposed to respond to ArtPolls, which OLA should be sending, and they then reply to.

[Vsevolod Ryabokon]

Hi! Tank you for replay!. I cannot patch the ArtNet universe as i see only my pc ip in ola_dev_info: 

 Device 1: ArtNet [192.168.0.185]

  port 0, IN, priority 100, RDM supported

  port 1, IN, priority 100, RDM supported

  port 2, IN, priority 100, RDM supported

  port 3, IN, priority 100, RDM supported

  port 0, OUT, RDM supported

  port 1, OUT, RDM supported

  port 2, OUT, RDM supported

  port 3, OUT, RDM supported

Or it is ok and i do not understand something. How can i patch artnet device, that has ip 192.168.0.105 and subnet 0 and universal 0?

And yes, i sow the broadcast packets only once when i changed net and subnet in ola-artnet.conf to 2 2.

Thank you!

I am sorry, i am new with artnet and ola. I tried to add universe 0- 3 with ArtNet [192.168.0.185] Output and seems start working.

[Peter Newman]

Excellent, glad you're sorted. Yes OLA is showing the IP it's bound to (i.e. the NIC on your machine that it will send ArtNet from). So you patch to an OLA universe and it will send/receive on that.
