Pokemon Go Plus Custom Badge

Installing Toolchain

This was all tested under Windows 10

1. Install Python 2.7 (This is tested by 2.7.12) This is required for the edf-sdk installer

2. Install CMake for Windows (Tested using 3.17.0)

3. Install espressif SDK (Tested using Windows installer 2.2) https://docs.espressif.com/projects/esp-idf/en/latest/get-started/#id1

I needed to use this because of an installer problem espressif/esp-idf#4744

python.exe -m pip install --upgrade virtualenv==16.7.9

Then run the program as administrator

Extracting a MAC, Blob, and Key

Note that this is unusable without a Mac address, BLOB and device key from an ORIGINAL Pokemon GO plus Pokeball plus and Gotcha not supported https://github.com/Jesus805/Suota-Go-Plus

It's easiest to use the release page app

To restore the FW

1. Write 0x01 to Characteristic 6b64be6f-5467-d8b5-7143-1716be1b96be
2. Disconnect from the device
3. Wait a few seconds
4. Press the Pokemon Go Plus button, it should be flashing blue or white

Building the firmware

1. Open a command window
2. Browse to the esp-idf folder and run export.bat to setup sdk

4. Exit using the default configuration
5. Modify your secrets.c file with your MAC, Blob, and Key extracted from an original Pokemon GO Plus - This file is not tracked by git
6. Build the firmware using idf.py build
7. Flash the firmware using idf.py -p (PORT) flash where (PORT) is the COMX that the esp32 enumerated as
