get attribute issues

[viy]

Hay, I have strange issue with prana-rc while getting state

curl \
  -X POST \
  -H "Accept: application/json" \
  http://192.168.1.32:8881/ \
  -d '{ "jsonrpc": "2.0", "id": 1, "method": "prana.get_state", "params": {"address": "00:A0:50:BD:51:DF"} }'
{"error": {"code": -32000, "message": "Server error", "data": {"type": "RuntimeError", "args": ["Connection to device 00:A0:50:BD:51:DF failed after 5 attempts"], "message": "Connection to device 00:A0:50:BD:51:DF failed after 5 attempts"}}, "id": 1, "jsonrpc": "2.0"}%    

But Btmot on the server actually returns

How can I get debug information from prana-rc server?

Try to add environment variable PRANA_LOGGING=true this should enable extensive logging (logs will be written into stdout).

I found this

looks like it was an unstable connection issue (( so no worries
