Communication issues - Openhab 3.0 issue

[gbleite]

Hello,

Whenever I have the system up and running, in case of communication issues (Arduino reboot or USB cable reconnection), the system is unable to recover.
Arduino reboot:

In this situation, I can see Arduino TX led blinking but nothing on RX side. When connection is reestablished, both leds are blinking without issue.

When cable is removed, i can reestablish the communication only disabling the Thigs and reenabling in a specific order: first bridge, once it is online, the generic thing. The issue is not 100% but the workaround works all the time.

Hello,

i have roughly the same issue. It appeard after the update from OH3 to OH4. But i can not get it to work the communication is always down. After enabling of the binding i get the following error:

2025-05-04 16:26:17.270 [INFO ] [andler.SimpleBinaryUartBridgeHandler] - Simplebinary_UART_RF_Bridge - Current charset UTF-8
2025-05-04 16:26:28.774 [WARN ] [inary.internal.core.SimpleBinaryUART] - Port /dev/ttyAMA0 - Device1 - Receiving data timeouted. Thread=22395
2025-05-04 16:26:28.778 [INFO ] [ernal.core.SimpleBinaryGenericDevice] - Port /dev/ttyAMA0 - Data in input buffer: [0x2]

2025-05-04 16:26:28.781 [INFO ] [ernal.core.SimpleBinaryGenericDevice] - Port /dev/ttyAMA0 - Device 1 not responding

But this is not true because i checked the serial port with an oszilloscope and the Slave with the device adress 1 answers correctly with the Acknowledge packet - "No new data". After the first "conversation" my slave answers never again which i think is because the message from the binding changed. I have to analyze it further with an logic analyzer. I keep you updated.
