I hope I'm in the right place...
Sometimes, after a reboot of my RPi3, my RFlink gateway can't be reached and i have this error :
Code: Select all
2018-09-12 13:07:31.777 Error: RFLink: Error opening serial port!
The only way I found to fix this, is to disconnect and reconnect the usb cable to make it work.
(I've already changed the usb cable, don't search this way)
I found a way to fix this without disconnecting the cable when the problem occurs using this trick. It's not very clear but it works, I'll find a way to clean this later.
The only thing left is to detect when the problem occurs.
Is there a way to active a dummy switch when the problem occurs or to detect the problem using a script and a cron job ?
Thanks a lot for your help !
