Thanks for this. As part of my explorations, I had installed ADB, but I run into this issue (although everything in your documentation up to this point checks out):
Davids-iMac:~ orgel$ adb shell settings put secure sleep_timeout 123456789
error: device offline
Any thoughts about what might cause the device to show as “offline”? It seems like I’m connecting successfully prior to issuing the shell-settings command…
Davids-iMac:~ orgel$ adb connect 192.168.7.71
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
