odas_web not running

[viduraakalanka]

Hi, I'm trying to use ODAS with Respeaker Mic Array V2.0 to perform sound source localization and tracking. When odas is launched after setting the corresponding config file, GUI output remains unchanged as follows.

Also when i execute the command "./odaslive -c ./ -v" , it results in the following error.

The config file i used is:

`# Configuration file for XMOS circular sound card

version = "2.1";

Raw

raw: {

fS = 16000;
hopSize = 128;

I think you should change your IP address(127.0.0.1)to 192.168.8.104 in the config file.

[viduraakalanka]

i tried that option. But it didn't help either. Any other ideas?? terminal output before changing IP (127.0.0.1)

terminal output after changing IP

Respeaker documentary has instruction to execute the odas_web: http://wiki.seeedstudio.com/ReSpeaker_Mic_Array_v2.0/

There they have mentioned to edit odas.cfg based on sound card number. I think the error might be there. How can i do it in my case?

Also I couldn't find any "odascore" file. So i used "odaslive" file for the odascore field. Could that be an issue?

[OtakuWang]

You can use "arecord -l" to see all soundcards and digital audio devices. No, you have already started the program, it should be some problem in the socket. Can you ping your Ip address? also try checking your ports to see if any of the ports [9000, 9001, 10000, 10010] is not listening.

[viduraakalanka]

I was able to solve the issue by changing IP address (as you mentioned before) as well as the device and index numbers to their proper values. Many thanks for supporting me to resolve this issue. :-)

Hello @viduraakalanka how can you save odas angle result ?
