rflink.0 (597) Module serialport is not available

[tnowak]

Hello,

I've moved my dockered ioBroker install from RPI3 to RPI4 and I can't debug one issue I have.
This is with RFLink adapter not seeing my Arduino.
Basically this what RFLink logs:

2020-09-17 02:05:14.046  - warn: rflink.0 (597) Module serialport is not available
2020-09-17 02:05:19.035  - warn: rflink.0 (597) Module serialport is not available

And this is what logs ioBroker itself:

Cannot load serialport module
Serial port is not available

Everything (docker container) seems to be configured exactly the same on RPI4 as it was on RPI3.
/dev/serial/by-id/usb-Arduino__www.arduino.cc__0042_557313234363513031A0-if00 is mapped to /dev/ttyACM0.
and ACM0 seems to show up in docker:

root@a54f0d9ed4df:/opt/iobroker/log# ls -l /dev/ | grep ttyA
crw-rw---- 1 root dialout 166, 0 Sep 17 02:03 ttyACM0

On this very same RPI4 I have Conbee II stick that is mapped to deCONZ docker and it works fine with deCONZ. So it doesn't seem like a RPI4 fault.

I'd really make use of some ideas how to diagnose and fix the problem, as I can't control my blinds right now.
Thanks in advance.

PS.

• js-controller 3.1.6
• Node.js: v12.18.3
• NPM: 6.14.6
• RFLink Adapter 2.0.0

PS2.
I also made iobroker fix but that did't help.

I somehow managed to fix this myself!
Don't know what this command actually does, but I've fixed it with issuing:

npm rebuild
in directory /opt/iobroker/node_modules/@serialport

So it works now, but I still don't see anything in "Com port" - its empty.
Is this Ok? Should't it say /dev/ttyACM0 or something?

If you moved stuff between is or node versions then sometimes native nodejs modules needs to be recompiled. This command does that. So this is fine

For empty port: the USB port is forwarded in Docker so that it is available and shows also in Docker /dev/tty...?!

[tnowak]

It shows in Docker as /dev/ttyACM0.
But doesn't show in adapter configuration in ioBroker - select filed next to Com port is empty

how did you solved it now.. have the same issue in Proxmox V8. Zigbe works like charm. but did not get RFlink on the run.
tried editing in Objects too. after starting rflink i always get:

btw hab auch nicht das "bin" verzeichnis das Apollon in einem anderen threat mal erwähnt hat.
"/opt/iobroker/node_modules/iobroker.rflink/node_modules/serialport/bin" hab ich nicht, aber auf keinem meiner Systeme....

[Apollon77]

@fraeggle I more think your issue is different! seels like a very old js-controller is used, could that be?

[fraeggle]

@Apollon77 fixed it with
npm rebuild
in directory /opt/iobroker/node_modules/https://github.com/serialport

Eigentlich bin ich aktuell
Node.js: v18.17.1
NPM: 9.6.7
js: 4.0.24

after i read, if you change to another "system", you should run npm rebuild, i did that. And after a short coffee break the serialports in lxc are available at rflink and it works.

Thanks.
Regard Peter
