Before the fix:
{"id":"58:2D:34:50:A0:D0","name":"Qingping Alarm Clock","rssi":-82,"distance":11.4949,"servicedata":"080cd0a050342d580104c0007c02"}
The servicedata string does not match any pattern so is not parsed
After the fix:
{"id":"58:2D:34:50:A0:D0","name":"Qingping Alarm Clock","rssi":-83,"distance":12.61001,"model":"CGD1","tem":19.2,"tempc":19.2,"tempf":66.56,"hum":63.5}
The parser is invoked and the data is output as expected.
There are probably too many brackets (I'm not a C dev) and I can't test on whatever version of CGD1 broadcasts 080caf or 080c09 servicedata strings.
