Can't connect to TCP

[dfein38347g]

I have channel B of this RS485 adapter (https://www.waveshare.com/2-ch-rs485-to-eth-b.htm) connected to between the CCA and the TAPs as described. However, I'm not able to make a connection with taptap. Please see my settings for the RS485 adapter and the results when I try to connect.

error: the argument '--tcp ' cannot be used with '--port '

It looks like taptap is wrongly thinking you can't use port with tcp, rather than only being valid with tcp. You could try having your adapter listen on port 7160, which is the default taptap will try and connect to.

Thanks! That seemed to work. It's connecting now but I'm not seeing any traffic, even after 10 minutes. Are the rest of my RS485 adapter settings correct?

Is it dark outside? Try using peek-frames or one of the others instead of observe - they always emit some data, even if it's just time frames

No, it's still light out and the optimizers are powered on. I was able to get something with the peek-bytes but not the others.

https://github.com/willglynn/taptap/blob/main/docs/protocol.md#gateway-physical-layer says 38400 8N1. From your screenshot you're at 9600. Try changing that.

That fixed it! Thanks a ton! @willglynn Perhaps you could put the required serial settings on the main readme page?

It looks like taptap is wrongly thinking you can't use port with tcp, rather than only being valid with tcp. You could try having your adapter listen on port 7160, which is the default taptap will try and connect to.

This is bug in the main.rs, somewhere around line 56

wrong:
#[group(required = true, multiple = false)]

correct:
#[group(required = true, multiple = true)]

https://github.com/willglynn/taptap/blob/main/docs/protocol.md#gateway-physical-layer dice 38400 8N1. Dal tuo screenshot sei a 9600. Prova a cambiarlo.

Ho risolto! Grazie milleForse potresti inserire le impostazioni seriali richieste nella pagina principale del file readme?

I have the same problem as you how did you solve it, with peek-bytes i can look data, the configuration of rs485 is correct 38400,8,n,1
