RP2040 BLE Component
The rp2040_ble component in ESPHome sets up the Bluetooth LE stack on RP2040 and RP2350 devices
using the BTstack library provided by the
arduino-pico framework.
This component requires a board with the Cypress/Infineon CYW43439 wireless chip, which provides both WiFi and Bluetooth 5.2 support. The Raspberry Pi Pico W and Pico 2 W are the most common boards with this chip.
NOTE
This component initializes the BLE stack and provides the scan primitives used by the RP2 BLE Tracker. The Bluetooth Proxy supports active GATT connections on this platform through BTstack’s GATT client.
NOTE
This component uses the BTstack Bluetooth stack, which is included in the pico-sdk. Raspberry Pi provides a royalty-free commercial license for BTstack when used on supported hardware (Pico W, Pico 2 W, and RM2). No additional licensing is required.
