9406f817f3 Instead of showing a mail button a small circle is shown next to the reload button.
The circle is orange if the mail plug-in is disabled
2021-03-15 10:36:28 +01:00
Alexander Heinrich
ab1c3eb83a Adding a button that shows if the mail plug-in is active. The button turns red if the plug-in is not active.
Architectural changes discussed with @schmittner: Moving the FindMyController out of the environment and using the AccessoryController as the main entry point, also for downloading reports
The AccessoryController is now passed as an Environment Object again

# OpenHaystack Firmware for ESP32
This project contains a PoC firmware for Espressif ESP32 chips (like ESP32-WROOM or ESP32-WROVER, but _not_ ESP32-S2).
After flashing our firmware, the device sends out Bluetooth Low Energy advertisements such that it can be found by [Apple's Find My network](https://developer.apple.com/find-my/).
## Disclaimer
Note that the firmware is just a proof-of-concept and currently only implements advertising a single static key. This means that **devices running this firmware are trackable** by other devices in proximity.
## Requirements
To change and rebuild the firmware, you need Espressif's IoT Development Framework (ESP-IDF).
Installation instructions for the latest version of the ESP-IDF can be found in [its documentation](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/).
The firmware is tested on version 4.2.
For deploying the firmware, you need Python 3 on your path, either as `python3` (preferred) or as `python`, and the `venv` module needs to be available.
## Build
With the ESP-IDF on your `$PATH`, you can use `idf.py` to build the application from within this directory:
```bash
idf.py build
```
This will create the following files:
- `build/bootloader/bootloader.bin` -- The second stage bootloader
- `build/partition_table/partition-table.bin` -- The partition table
- `build/openhaystack.bin` -- The application itself
These files are required for the next step: Deploy the firmware.
## Deploy the Firmware
Use the `flash_esp32.sh` script to deploy the firmware and a public key to an ESP32 device connected to your local machine:
```bash
./flash_esp32.sh -p /dev/yourSerialPort "public-key-in-base64"
```
> **Note:** You might need to reset your device after running the script before it starts sending advertisements.
For more options, see `./flash-esp32.h --help`.
