RFLink message not decoded due to NumberFormatException: Infinite or NaN

Hello,
I have a MyController installation on a RaspberryPi
Version 1.5.0
Database schema revision

Database type
H2 database embedded

Java virtual machine specification

I get this error only in WINDIR WINGS message
for example this message

20;4e;Alecto V1;ID=0005;WINDIR=0012;WINGS=001c;BAT=OK;\r

I get this error
2020-05-02 17:20:14,053 ERROR [Thread-26] [org.mycontroller.standalone.gateway.serial.SerialDataListenerjSerialComm:201] Exception, RawMessage:[20;4e;Alecto V1;ID=0005;WINDIR=0012;WINGS=001c;BAT=OK;\r]

It happens only with this message, RAIN, TEMP & HUM and WINSP are decoded.

@zoomx
I guess that WINSP = windspeed and that WINDIR = wind direction and WINGS = wind ground speed. Is that right?

If you connect the node to a PC and view data sent via arduino serial monitor what does it show for those values?

I had issues with DHT11 sensor which occasionally gave a NAN for a reading. I solved this by testing for NAN in the node sketch and not transmitting the value if NAN was detected.

The full code of your node would help.

I opened an issue in github also.

RFlink protocol is here

http://www.rflink.nl/blog2/protref

The error message is referred to the message show above, this one
20;4e;Alecto V1;ID=0005;WINDIR=0012;WINGS=001c;BAT=OK;\r

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.
