Let's Begin

This brief tutorial aims to help people fix the black screen / blank screen issue that affects many DJI Phantom 2 Vision+ Plus quadcopters out there. There are tons of forum posts about people who store their drone for a few months and turn it on to find that there is no streaming video to the app. Or others had everything working fine, then they update the quad only to lose the ability to view live streaming FPV footage while flying.

Problem: DJI Phantom 2 Vision+ works fine, has a wifi connection to the app, transmits telemetry and GPS status fine, but no live FPV video streaming while flying

Hypotheses: wifi module (air side, inside the drone) is bad

If you have this problem, your options are:

EITHER

  • Buy new module ($150-$250 on eBay)

OR

  • Reflash wifi module firmware to fix / reflash corrupt NAND memory chips

    • We're going to discuss the "fix it" option in the tutorial below


What you'll need:

  1. Tinksky FT232RL FTDI USB2.0 to TTL Serial Converter Adapter http://amzn.to/2oVcH2J

    1. A USB mini to USB B cable to connect the above TTL board to your PC. Get one like this one on Amazon if you don't have one.

  2. Download the Flash utility and binaries for phantom 2 vision plus wifi module firmware

  3. Tera Term or similar serial terminal software (allows you to see results from the serial connection you are going to make between the wifi board and your computer)

  4. Soldering iron

    1. solder

    2. small wires to connect the USB TTL adapter to the pads on the wifi board

  5. Screw drivers to extract the wifi module from the quad


Section 1: Hardware Process

  • Open the quad, extract the wifi module, open the wifi module, remove the lower pc board (labeled WM301_DM368)

  • Take the lower board out, it looks like this:

  • Connect up the USB2.0 to TTL Serial Converter as follows:

Tips:

  • Use a small blade or small file to rough up the pads on the pc board so solder will flow and make a good connection to your wiring. And pre-solder the pads and wires before soldering the two together for best results.

  • NOTE: there are many USB TTL boards out there with various pin orders. Look carefully at your board's pin layout and make sure you are connecting the TTL's TX pin to the module's RX, and the TTL's RX to the module's TX.
