Thank you Milosz and Antonio for your answers.
Now I can send and automatically receive status (Fail , Pass) but I'm receiving measurements automatically only for tests the uses one board (DUT).
As I have communication tests using 2 or more boards, there 2 or more lava test IDs, one for each board.
After Squad test submission, in /admin is signed as "fetched"
Failure field says: <Fault -32603: 'Internal Server Error (contact server administrator for details): No TestJob matches the given query.'>
Job id: ['38721.0', '38721.1']
I suppose lava is complaining about the ID list.
Also if I click on Squad /admin job id link : http://lava.company.com/scheduler/job/%5B%2738721.0%27,%20%2738721.1']
