Setup UNMS and Unifi network controller on Raspberry pi 4 Raspbian buster

Setup Raspbian Buster

I'm using debian 10 as my daily so these are *nix commands. Mac should work with these too but you're on your own if you're using Windows. Goal for me is to make a headless raspberry pi I can SSH into and connect to my network using Ethernet. You should be comfortable in command line if you choose to follow this guide.

  1. Go to https://www.raspberrypi.org/downloads/raspbian and download Raspbian lite archive
  2. unzip the image
  3. Plug in sdcard. Run lsblk to see drives and mount points. Likely, the sdcard will show up in /dev/sda or /dev/sdb and may have some partitions like /dev/sda1 and /dev/sda2.
  4. If partitions are mounted, unmount all of them. Ex: umount /dev/sda1 and umount /dev/sda2
  5. Copy the raspbian image to the sdcard with sudo dd if=RASPBIAN_IMAGE_FILE.img of=/dev/sda bs=4M
  6. Run sync to ensure the written contents are flushed
  7. OPTIONAL: To start ssh server on boot, Unplug sdcard and reinsert to remount new partitions. You'll have two with raspbian.

Android Marshmallow Idle Mode Behavior

What is "idle mode"?

Idle mode is a state where the phone has no network connectivity and apps are temporarily suspended. Idle mode gets triggered by one of two ways: an asleep, still, unplugged phone (Doze mode), and when an app has not been opened in a significant amount of time (App Standby Mode). During idle mode via Doze, the phone will wake up periodically for a short amount of time, allowing apps to run and use network connectivity. Using several different methods outlined below, it is possible to wake apps up during idle mode outside of these maintenance windows.

Time to enter Doze mode

1 hour of being still after the screen turns off.

Time to enter App Standby mode

TBD
