TWC and EW11 socket options

[revoneor]

How to start twcmanager without a usb dongle when one is having a EW11 RS485 to socket

First attempt is to remove devices from the docker compose.yaml (comment out) and hope that twcmanager gets so far as to create /etc/twcmanage/config.json (Could be that one should put this file there manually then and edit)

It did not create this file because it barks that /dev/ttyUSB0 is not found, I tried to have it pass that by listing my /dev/ttyACM0 in the docker-compose.yml but it would still barf on missing /dev/ttyUSB0

Luckily I had one RS485 USB dongle but otherwise I see no way to fake it to get it to work

With that it started and /etc/twcmanage/config.json could be edited to for socket: ip:port and restart.

Is there or should there be a syntax to have a socket line in docker-compose.yml?

The above is still an issue.

Apart from that exception handling may be failing when the socket seems to not respond or get closed involuntarily.

It works fine and then:

could it be that

else: actualDataLen = dataLen dataLen = 1 data = master.getInterfaceModule().read(dataLen)

in twcmanager.py lacks exception handling in the while true loop?

If I docker stop and start it works again, it seems a lost socket is not reconnected in the loop ?

[revoneor]

Actually after fiddling with the EW11 and making sure that DHCP off and AP off, and docker log files were not overfilling my emmc it is sort of stable. Probably wifi channel disconnecting issues.

Original issue still has some validity, there is no re-connect on port as a socket.

I fixed these errors with bash inside the docker
