Read your log message. This is not a valid JSON string:
'{"a_flw_fwd":12,"a_flw_rtr":5029,"a_rpm":519,"b_flw_fwd":23,"b_flw_rtr":8,"b_rpm":913}'
Presumably your objective is to receive something like this instead:
{"a_flw_fwd":12,"a_flw_rtr":5029,"a_rpm":519,"b_flw_fwd":23,"b_flw_rtr":8,"b_rpm":913}
The problem is unrelated to Twisted or the console. The sender is
sending the wrong data, or else your parsing of it is incorrect.
