Rasbberry pi domoticz + arduino nano connection problem

[WiktorDIY]

Hello,
I have a problem with connecting CH340 arduino nano to domoticz that i installed on raspberry pi.
When I was testing in on pc (example relay actuator on arduino) everything was fine, but raspberry in not showing in domoticz.
Has anyone any suggestions?

@WiktorDIY The ch340 are notorious for being broken. The best I ever achieved was 19200 and flakey..

I purchased a real Nano not a ch knock off eg uses a different uart no problems
