File Glider

Wirelessly transfer files to and from file transfer ready Bluetooth Low Energy (BLE) or Wi-Fi firmware.  Browse and edit files from within File Glider or use the Files app integration to access the files from other apps.  Multiple devices can be managed at once and access can be shared amongst multiple apps.

Compatible devices:

• nrf52840 boards running CircuitPython
• ESP32-S2 TFT

The file transfer protocol is open so you can use File Glider with custom firmware. See GitHub for protocol details: https://github.com/adafruit/Adafruit_CircuitPython_BLE_File_Transfer
