Wireless SWD debug probe firmware for ESP32 series.

• Wireless flashing and debugging over Bluetooth Low Energy (BLE)
  • Supports Arm Cortex-M microcontrollers with Serial Wire Debug (SWD) ports
  • Suitable for development of moving devices such as robots
• Compatibility with existing software such as probe-rs and OpenOCD
  • This is because bluedap implements CMSIS-DAP v1 (HID-based) protocol on BLE HID-over-GATT Profile (HOGP)

1. Compile and flash bluedap firmware on an ESP32-series microcontroller (tested on ESP32C3), using ESP-IDF environment.
2. Connect the ESP and target device

   ESP	Target	Remarks
   GPIO4	SWCLK
   GPIO5	SWDIO
   GPIO6	RESET	(optional)

3. Plug the ESP into USB port of a PC and open serial console.
4. On a PC, pair a Bluetooth LE device named bluedap CMSIS-DAP or bluedap. The required PIN code is displayed on the serial console.
5. Now you can use your favorite CMSIS-DAP-compatible software! Pairing using serial console is no longer needed for subsequent uses.

• Faster communication using LE 2M PHY
• JTAG support for non-Arm targets
• Virtual serial port

• yswallow/nRF52_BLE_DAP: Preceding BLE CMSIS-DAP probe using Nordic nRF chip.
• windowsair/wireless-esp8266-dap: ESP-based wireless CMSIS-DAP using Wi-Fi and USBIP.
