Receiving simple UDP on HC2

[Tim__ 112]

Has anyone successfully received a UDP message on an HC2? There has been some previous discussion on here, but I could not locate any success.

 

I have this code running in a Virtual Device's main loop:

Please login or register to see this code.

 

I then send some test messages using ncat.exe from my PC (which is at 192.168.30.26) to HC2 (at 192.168.60.220)

 

C:\ncat -u 192.168.60.220 40002

 

Once I press enter to send the message, I get a response from ncat "Ncat: An existing connection was forcibly closed by the remote host.", and the HC2 code    fibaro:debug('Buffer: '..buffer);   returns nothing in the debug screen.  Is my UDP receive code incorrect, or does HC2 just not support UDP?

 

I plan to send a message from an Arduino I control (so I can select the message and selected port etc), and when the HC2 receives it, I will store the message in a global variable.  The message is a simple "1", indicating that the smoke alarm has been activated. I chose UDP because I thought it was a simple interface.  If UDP doesn't work, is there is another way to achieve this without setting up a middle man (like MQTT)?

Hi @Tim_

 

Did you get this sorted? I am trying a similar process to get the HC2 to receive messages from another controller. Like you it is just simple string e.g. "12+" to indicate motion sensor 12 has been tripped.

Nope.  I concluded that UDP isn't supported.  Instead, I resorted to connecting a sensor wire from the smoke alarms (via a relay), to the second channel of a Fibaro Switch 2,

Thanks anyway. ?

I did just come across this in the Fibaro LUA developer document, haven't investigated it though.  Maybe it means that to use UDP you have to include this code library.

 

The FUdpSocket class provides a UDP socket.
To use this class you should require it in pluginName.lua
require('net.UDPSocket')

Thanks Tim. Much appreciated. I will check this out.
