Via ETS: Programming the physical address only works very rarely. Mostly never. At some point, with luck, it works.

Hello everyone. I have a question. I have the example knx-demo.ino working in Platform IO. knx-demo-ip.knxprod works.

I have already made my own project. Not much changed. Just adapted the channels. But everything is still on a demo basis.

Via ETS: Programming the physical address only works very rarely. Mostly never. At some point, with luck, it works. Then I can transfer the application program over and over again. Always works perfectly. No matter how often, it works great.

I delete the ESP. Then I can no longer get the device programmed via ETS With a lot of patience and luck, it works at some point. Can't say what the problem is.

Can anyone tell me where I could look? What information do you need? Possibly my project?

Its hard to say what the problem is. You probably have compare the telegrams ETS sends and receives with the one the devices sends and recieves. People were having issues with igmp-proxies. Maybe that's your problem too.

The hex codes are hard to read. It might be good to add a toString() method to the CemiFrame class and print them out in DataLinkLayer::frameReceived and IpDataLinkLayer::sendFrame (it would be even better to add it to DataLinkLayer::sendFrame but this requires a bit more work, as DataLinkLayer::sendFrame is currently a pure virtual method.

Proxy is not aktiv.

I added more logging in the devel branch. If you set the ApplicationLayer Logger to Info you should be able to spot the difference between ets monitor and the telegrams that reach the device.
