Rumors of official Bluetooth support for the $6 Raspberry Pi Pico W have been running since early 2023. Developers who prefer C/C++ received support in February. through a blog post today From Raspberry Pi LTD CEO Eben Upton, MicroPython developers can now create Bluetooth projects using their favorite microcontroller thanks to the latest MicroPython build.
The Raspberry Pi Pico W’s wireless chip, the Infineon CYW43439, provides both 2.4 GHz Wi-Fi and Bluetooth 5.2 via a 3-pin SPI bus between itself and the RP2040 SoC. The latest MicroPython update supports Bluetooth Classic (ACL/SSO is not yet supported), BLE Central and Peripheral roles. Bluetooth Classic and BLE can be enabled independently. Or at the same time.
The good news is that there is no rush to buy a new Raspberry Pi Pico W. Since this is a software update, please work with Damien George, creator of Raspberry Pi, Infineon, and MicroPython. All you have to do is download Get the latest update and flash it to your Raspberry Pi Pico W.Also updated with Alasdair Allan’s excellent update documentation. a book, Connect to the Internet with Raspberry Pi Pico W It shows how easy it is to create a Bluetooth project using the Raspberry Pi Pico W.
We are currently adding support for MicroPython, so it should be a while before we add support for CircuitPython as well.
