Daly bms connects en disconnects every 5 seconds

[Barpo]

Daly bms connects en disconnects every 5 to 10 seconds.

tail -f /data/log/serial-starter/current also shows the start of the dbus-serialbattery at the same time.

I use Venus Version 2.66 on my Raspberry Pi Daly 3Cell for testing, interface USB-RS485 and the USB-RS232 from daly or the FTDI: all the same problem...

@Barpo can you please look at the dbus-serialbattery logs if you see anything in there that will help See https://github.com/Louisvdw/dbus-serialbattery/wiki/Troubleshoot

[neoneddy]

Ok, odd. Left it connected for a few days. Seems stable now.

I also installed this via USB for another friend and it all worked great out of the box, but was a 4s vs mine is an 8s . Not sure this needs to be opened back up.

[Louisvdw]

@neoneddy you error seem to be from the underlying serial library, which indicates it might be a low level error. My first though would be that is could be a wire/plug that is loose and that is hamperring signals. The wire might settle over time (gravity :) ). If you move the cable a bit and it start giving errors that would be a clear indication.

[neoneddy]

@Louisvdw rebooted after updating to venus OS 2.73 , Started reconnecting in a loop again, been going on for a day or two now.

I also run GUI Mods if that matters. I can try and reseat the UART cable. I am also connecting 4 dongles via a USB hub, I could could try connecting directly, I ran a 10ft USB extension cable to add this 5th device. I have BMV, 2x Solar, Multiplus, and now the Daly. Maybe putting Daly on it's own USB line might help.

Thanks for response.

[Louisvdw]

@neoneddy those are all good things to try. Check that the error in the log file is the IOError: [Errno 71] Protocol error. (should be the last line of a loop). I also use a 4port USB hub (MPPTx2, MK3, BMSx2) on my Pi3 testing hub so in itself that would not be an issue, but long cables and extra things could lead to cable loss. If you can run a test with the BMS connected to the GX directly you can see if that then works or not, and go from there

[neoneddy]

Ok, just switched the Daly BMS to its own USB port on the Pi and it’s online now and has a stable connection.

got some other goofy issues I might need to ask Victron Community About

[Louisvdw]

I found according to Wikipedia the USB specification allows for 5m cable for USB1.1 and USB2 and 3m cable for USB3. You might need to add a booster or powered hub to get longer distances. https://en.wikipedia.org/wiki/USB_hardware#Cabling
