## What it is
Send My is a research tool that transmits arbitrary data through Apple's Find My network by encoding it in BLE public-key broadcasts from an ESP32 microcontroller. It includes ESP32 firmware acting as a serial modem and a macOS DataFetcher app to retrieve and decode the uploaded data.

## Use cases
- send data from a device with no internet connection
- exfiltrate data over Apple's Find My network
- build a BLE-based covert channel with ESP32
- research the Find My offline finding protocol
- transfer small messages via nearby Apple devices

## When to choose
- you need one-way data transfer from an air-gapped or offline device
- you're researching or demonstrating Find My network abuse
- you have an ESP32 and a Mac to retrieve reports

## When to avoid
- you need reliable, high-bandwidth or bidirectional communication
- you need a production-ready or supported data transfer solution
- you don't control Apple devices to fetch the reports

## Facets
- artifact type: application
- maturity: maintenance
- function: security, networking, embedded
- domain: security, privacy, apple-ecosystem, embedded-systems
- platform: embedded, cpp
- tags: find-my, airtag, ble, esp32, data-exfiltration, openhaystack, offline-data-transfer, macos
