Re: KNX interface

Hi Abboud,

As far as I know, KNX has a KNX-->RS232 interface you can use to control the ESP using the serial port.

Hi Abboud,

I heard from a dealer that this KNX Inferface is working fine with ESP.

Re: KNX interface

Hi Team,

Do you have the command strings for the KNX serial communication to use with EX1280?
Bose serial command format was not working through KNX module.(model : spaceLynk Schneider).

Thanks in advance.

Re: KNX interface

Hello Varun,

The serial protocol shows the commands the Bose ControlSpace products work with.
Please check the RS232 settings and see what commands are sent by the KNX module.
Perhaps try to swap the TX and RX lines?

Re: KNX interface

Dear Arno,

Thank you very much for the reply.
Details are as given below:

Device:Spacelynk (LSS100200) as a gateway for KNX to RS232

 

Example command:

 

Mute Function :

require('serial')
port = serial.open('/dev/RS232', {
baudrate = 115200,
databits = 8,
stopbits = 1,
parity = 'none',
duplex = 'full'
})
port:write('SM 3,1,M<CR>')
port:close()

 

 

Thanks for the help
