Installing the firmware

• Step 1

  Get a blank microSD card of 8GB or larger. Insert the microSD card into the card reader

• Step 2

  Download ZIP-archive with firmware content

• Step 3

  Extract .img file from downloaded ZIP archive

• Step 4

  Use Win32DiskImager on Windows or Balena Etcher on Mac and write .img file on microSD card

• Step 5

  Insert the microSD card into the Raspberry Pi

• Step 6

  If you have a monitor or a TV with HDMI input - plug it to the Raspberry Pi HDMI port. For Raspberry Pi 4B use HDMI0 port (nearest to USB-C port)

• Step 7

  Plug a standard USB power supply or powerbank to the Raspberry Pi. Pi must start booting. A couple of reboots may be during the first boot process

Raspberry Pi power

All Raspberry Pi models has an own power scheme. Raspberry Pi may be powered from standard power input - micro-USB or USB-C port (RPI4B only), from GPIO, from PoE.

RPI4B only: when USB-C is busy for camera connection - need to power RPI from GPIO or with PoE.

• Standard micro-USB or USB-C power input

• Power with GPIO

You could use any USB cable, need to cut it and connect to the RPI only 2 wires - Red (5V) and Black (Gnd). Then you can use it with any standard USB power supply or powerbank.

 

• Power with PoE

Only for Raspberry Pi 4B and 3B+

I haven't tested yet, but my clients are reporting that it worked. Need to use PoE Hat

 

Network connection

• Step 1

  • For Ethernet connection from PC to Raspberry Pi

    Only for Raspberry Pi versions with Ethernet port. Connect Ethernet cable to the Raspberry Pi Ethernet port at one side and home router or PC/Mac Ethernet port on another side

  • For Wi-Fi connection from PC to Raspberry Pi

    Connect your PC/Mac to Wi-Fi network cosmostreamer, password 1234512345

• Step 2

  Download, install and run CosmoViewerNG application. For Windows, for Mac

• Step 3

  The Cosmostreamer device should be detected and displayed in the CosmoViewerNG device list.

• Step 4

  Also you could open Cosmostreamer web admin page in browser
  • http://192.168.50.1

Firmware update

When i fixing a bugs or adding some new functions - i publish a firmware update file. It's a small archive with software. Not needed to install a full microSD image, need just to install update file in web interface or in CosmoViewerNG application.

• Step 1

  Run CosmoViewerNG for Win or for Mac (or web admin page) and open device settings, chapter "System"

• Step 2

  Download the Latest firmware update file

• Step 3

  Choose downloaded update file (with .csuf extension) in "Firmware update" field and press "Upload file" button.

• Step 4

  Raspberry Pi must goes to reboot automatically after update installed

Changing camera type

• Step 1

  Open device settings in CosmoViewerNG application or in web interface, chapter "Info". Choose camera type "DJI FPV Goggles". Don't forget to click "Save" button.

License key

License key is a text string, unique for each device. Each camera type needs different license keys. It's possible to install multiple amount of license keys on one device and use this device for some camera types, i.e. Pocket Osmo, Pocket 2, and others. Additional licenses price is much lower.

• Step 1

  Buy license key on a product page

• Step 2

  Make a photo of HDMI display or screenshot of the app with a QR image and send it to me for making a license key

• Step 3

  When you got a license key - use web interface or CosmoViewerNG application, menu "device settings" -> "License" and insert license key into field. And click "Install license" button.

DJI FPV Goggles connection

Use any standard USB-C cable and plug it into Raspberry Pi USB port. That's all.
