Need help with ser2net

[Jochen]

What i want to do:
I have one Raspberry PI where i connect my RFXtrx433 USB
And i have another PI where i want to use the RFXtrx433 USB also.

Is this possible? Is ser2net the right tool to do that?
Can someone help me?

Thanks,
Jochen

Why don't you use built in sharing of domoticz?

The second PI is my "development-machine" where i want to test my own software.
I will try to create an decoder for undecodet signals.
And there i don´t want to use domoticz.
I want to call the RFX directly and not requesting the status of devices.

Can someone add to Wiki the rest of process? https://www.domoticz.com/wiki/SharingSerialDevices

After installing ser2net and setting .conf-file you can add new hardware into Domoticz -> "RFXCOM - RFXtrx shared over LAN interface" with remote machine IP and .conf-file port.

Does someone knows correct baudrate settings for RFXCom? I use "3001:raw:0:/dev/ttyUSB0:38400 8DATABITS NONE 1STOPBIT" and it seems to transmit ok, but I don't have any sensors into other end.

Is it confusing if there is settings for different devices in wiki (Z-wave, RFXCom, etc.)?

Also maybe mention about using dmesg | grep tty in remote machine to find out name of the serial port.

Yes I watch it, but in my case I find much more easier just use ser2net. I don't need any client to run in my Pi server. I even try to test VirtualHere, but it doesn't worked instantly - more or less my fault, because I cant use it - and ser2net does, so thats my winner here.

What are advantages in VirtualHere against ser2net?

(I still miss IRQs and DMAs... )

Disable Serial Console
======================
sudo nano /etc/inittab
insert a # sign in front of this line:
T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100
ctrl-O
Enter
ctrl-x

Remove console
==============
sudo nano /boot/cmdline.txt
delete these 2 fields: console=ttyAMA0,115200 kgdboc=ttyAMA0,115200
ctrl-O
Enter
ctrl-x

Add ser2net
===========
sudo apt-get install ser2net

sudo nano /etc/ser2net.conf
10001:raw:0:/dev/ttyUSB0:38400 8DATABITS NONE 1STOPBIT
10002:raw:0:/dev/ttyUSB1:38400 8DATABITS NONE 1STOPBIT

sudo /etc/init.d/ser2net restart

Autostart ser2net
=================
sudo nano /etc/rc.local

add the next line before exit o :
/usr/local/sbin/ser2net -n

May I ask what is that serial console for? I suppose ttyAMA0 is serial via Raspberry GPIO.
Also what is USB1 in ser2net.conf?

EDIT: Ok. Found some additional info from here: http://www.hobbytronics.co.uk/raspberry-pi-serial-port

EDIT2: Now I don't understand why GPIO serial port has to be disconnected from Linux to use ser2net with ttyUSB0?

You connect 2 RFXtrx devices and access the 1st RFXtrx on port 10001 and the 2nd RFXtrx on port 10002

Thank you.
So in my case when other RFXCom is connected straight into server I just use USB0.

Seems simple - at least it is working now.
