sending command 'give device power status' failed (4)

[Bouni]

I've managed to build the binary (see #1) and it works partially, but I see several errors throughout the logs.

When I restart the application, everything seems to work just fine (kind of). I send a curl http://localhost:5000/device and the result is

{
   "Recording":{
      "OSDName":"cec.go\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000",
      "Vendor":"Pulse Eight",
      "LogicalAddress":1,
      "ActiveSource":false,
      "PowerStatus":"on",
      "PhysicalAddress":"2.0.0.0"
   },
   "TV":{
      "OSDName":"TV\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000",
      "Vendor":"Samsung",
      "LogicalAddress":0,
      "ActiveSource":false,
      "PowerStatus":"",
      "PhysicalAddress":"2.0.0.0"
   }
}

The PowerStatus of the TV is reported as "" and in the logs I see a lot of these:

08:56:33 command 'give device power status' timeout
08:56:33 << 10:8f
08:56:33 unhandled response received: opcode=8f initiator=e destination=0 response=0
08:56:33 command 'give device power status' timeout
08:56:33 TV (0): power status changed from 'standby' to 'unknown'
08:56:33 >> 0e:90:01
08:56:33 TV (0): power status changed from 'unknown' to 'standby'

It seems that the TV does not respond quick enough and therfore the application reports a timout!?

If I send a request for the power status I get the same result, but If I send another emediately after the first I get the correct power status:

$ curl http://localhost:5000/device/0/power
{"state":""}
$ curl http://localhost:5000/device/0/power
{"state":"standby"}

Any ideas where to search for the problem?
