MC31 battery suspend after 30 minutes regfile

Dear collegues,

i am looking for a simple .reg file that sets my device suspend on 30 minutes (something simular as the nosleep.reg ).

In the device i can only set it to max 5 minutes of awake time, and this is a little to low for the client, but a full nosleep is a bit harsh for the device and the battery as well.

 

With kind regards,
