running at nanopi

[pahorpet]

As the code is running on several devices would it be possible to run it at nanopi? multi/easysolar GX. It crash on : file "/usr/lib/python3.8/site-packages/serial/serialposix.py", line 595, in reset_input_buffer termios.tcflush(self.fd, termios.TCIFLUSCH) termios.error: (25, 'Inappropriate ioctl for device')

any hints to fix would be appreciated, also able to test.

It is suppose to work but seems that the IO control is getting an error. I suspect this would be a VenusOS issue. Or it might be the pyserial lib on that device where something is not supported.

My standard setup is a MultiplusII GX. The integrated GX device calls itself nanopi. At least one (of three connected DALY BMS could be seen at the same time without severe crash). However I found some errors in the LOG which is unfimilar with yours and furthermore are not crashing the driver at all: @40000000628f9dc02e73f5cc Traceback (most recent call last): @40000000628f9dc02e7424ac File "/data/etc/dbus-serialbattery/dbushelper.py", line 142, in publish_battery @40000000628f9dc02e743064 success = self.battery.refresh_data() @40000000628f9dc02e743c1c File "/data/etc/dbus-serialbattery/daly.py", line 49, in refresh_data @40000000628f9dc02e7447d4 result = result and self.read_fed_data() @40000000628f9dc02e744fa4 File "/data/etc/dbus-serialbattery/daly.py", line 108, in read_fed_data @40000000628f9dc02e745b5c fed_data = self.read_serial_data_daly(self.command_fet) @40000000628f9dc02e771a7c File "/data/etc/dbus-serialbattery/daly.py", line 125, in read_serial_data_daly @40000000628f9dc02e772e04 data = read_serial_data(self.generate_command(command), self.port, self.baud_rate, self.LENGTH_POS, self.LENGTH_CHECK) @40000000628f9dc02e77418c File "/data/etc/dbus-serialbattery/utils.py", line 61, in read_serial_data @40000000628f9dc02e774d44 toread = ser.inWaiting() @40000000628f9dc02e77512c File "/usr/lib/python3.8/site-packages/serial/serialutil.py", line 590, in inWaiting @40000000628f9dc02e77ddcc return self.in_waiting @40000000628f9dc02e77ed6c File "/usr/lib/python3.8/site-packages/serial/serialposix.py", line 467, in in_waiting @40000000628f9dc02e77f924 s = fcntl.ioctl(self.fd, TIOCINQ, TIOCM_zero_str) @40000000628f9dc02e7804dc OSError: [Errno 5] Input/output error @40000000628f9dc038ca71cc /opt/victronenergy/serial-starter/run-service.sh: line 15: kill: (2444) - No such process

So, i´m able to connect at least one DALY BMS via a isolated UART-USB Adapter with genuine FTDI device under Venus OS v2.85. Are there additional USB-Serial devices connected via VE-Direct (USB-UART cable) ? Could you figure out which TtyUSB devices are mapped to your BMS and to other functions (MK3 IF, internal CAN-IF etc,. and your connected USB-UARTs. Furthermore there is a possibility of non-genius FTDI chips seen sometimes which seems to be less stable and tend to through errors via USB communication.

Also here no problems with nanopi on gx board in Multiplus ik. Venus version 2.90. Perhaps van @pahorpet try it with version 2.90 of Venus os?

I have also no problems on my MultiPlus II-GX with Venus OS 2.92 and driver version 0.14.3
