As expected the raspberry pi foundation have announced that they are ceasing production of 1Gb raspberry pi models. The falling price of ram on the open market and demand from users for more ram both contriubted to this action.
Now the entry level pi comes with 2Gb ram and has also seen a £10.00 price reduction to under £35.00 in the UK.
I opened an issue in github also.
RFlink protocol is here
The error message is referred to the message show above, this one
20 mean a messagr from RFlink
4e is the message number
ID is the sensor ID
WINDIR is the wind direction
WINGS is the wind speed gust
Al messages are in ASCIII, there is not any NaN or strange values like the DHT ones.
It happens with all WINDIR messages, no one is decoded.
Data are captured and decoded from a meteo station sensors at 433MHz
But you give me a good suggestion, maybe there is a character in message not printed in the error, so I will check on a PC in HEX also.
Edit: Check done, all ascii chars plus CR+LF at the end
I don't understand why this happens on this message and not with others.
I watched on my controllers code and I don't see any bug.
