Failing to start #23

Closed rosenhauer closed 11 months ago

rosenhauer commented 2 years ago

I was getting no response in MQTT so I started researching and ran the "Start" commend manually so I could see the results.

sudo /usr/local/bin/aurora_mqtt_bridge /dev/ttyUSB0 mqtt://localhost/

yields

/var/lib/gems/3.0.0/gems/rmodbus-ccutrer-2.1.0/lib/rmodbus/client/slave.rb:275:in 'rescue in query': Timed out during read attempt I have confirmed that I am referencing the correct device ttyUSB0. I also can see on a RS-485 Module on an ESP32 that is also connected to the buss that there is data sent

61 40 0C 61 61 61 58 76 54 61 7C 62 A8 40 64 02 61 A6 40 62 FF

That packet is sent twice before it gives the timeout error.

I do have a different model USB to RS-485 Adapter than you show You list the DSD TECH SH-U11 USB to RS485 RS422 and I have the DSD TECH SH-U10 USB to RS485 Converter. Could that be the issue or do I have something else going on?

I have a Series 7 but am unsure of the Firmware version. Edit: I was able to send commands from the ESP32 and get that the ABC Program Version is 2.04 from register 2.

Did you ever find a solution to this? I recently bought an adapter with a CP2012 chip. I believe I've wired it correctly, the driver appears to be installed (loaded with /etc/modules) on RPi 3B bullseye, /dev/ttyUSB0 is present, and the device shows up on lsusb, but when I try the test you described above, I get the same "timed out" error message. Everything works when I use the adapter that is linked to Amazon in the original writeup.
