I am trying to read the brightness parameter of blue Led of omega2 to use it in a variable to use this to manage a led in my frontplate of my box with omega 2lte. I do not know what i do wrong. here is the essential part of the python script I use:

while True:
w = os.system("cat /sys/class/leds/omega2lte:blue:wifi/brightness")
if w == 255:
status2 = "connected"
status = gpioObj.setValue(0)
print(status2)

The frontplate shows if I am connected to my application via mobile ( iot ) or via wifi, if there is no good radio connection to mobile iot
If I look in logread I see that the cat command shows the correct value of 255 and but the ïf in the programm does not see the variable.
Van some body help me with this?

I tried everything I found on internet and in community posts to get the sdcard show up and mounted.
I just bought 3 new Omega2+ LTE (global). They do not mount several SDcards I tried on them.
Version Ω-ware: 0.3.3.b251
I also have 2 other units bought 2 years ago, they work as should. To pay 300 euro for equipment that does not complete work is a little bitter.
I need that CD card because we use it to boot Omega 2+ LTE and use it for the overlay.
I hope that Lazar Demin will answer very soon to solve this problem or some one who had the same problem. Till now our new telecaredevices are delayed by this.

I connect Omega2 lte to "IOT" at T-Mobile with special SIM. I installed client openvpn machine and connection works with portal and get IP address . The omega2 lte makes only a connection to client if I enter terminal command "lted" ,It connects and gets IP . client can ping omega2 LTE. Command "lted"in terminal isn''t closed. Entering CNTR-C I get cursor back, but the connection via LTE shuts down. What Do I wrong or what is not correct configured```
