wifimanager over 90% CPU usage - Omega2p

Venet

Seems the wifimanager process is the culprit for high CPU usage and Omega2 getting very hot (as reported by others).

In my omega it was constantly using over 95% CPU (see attached) and the omega LED kept blinking.

Disabled it from starting in /etc/init.d and now Omega runs cool. LED is also steady.

By the way, disabling wifimanager was also a solution to Omega2 not rebooting (Device Firmware Version: 0.1.10 b160)

@György-Farkas I'm not sure I understand the question. Are you asking how to disable wifimanager?

If so this can be done through

/etc/init.d/wifimanager stop
/etc/init.d/wifimanager disable

@Venet
I am watching my O2+ via serial terminal and / or via ssh (connecting to Omega's Wifi AP).
I can not run wifimanager and top at the same to see that nice

%CPU
99 % {wifimanager}

How did you do that?

OK. A shell script might help me a lot

I see. On my Omega2 wifimanager was set to run on boot, so I didn't start it manually.

I think the problem with wifimanager is that if it is run manually it never completes (as others also found in another thread).
