 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

https://www.raspberrypi.com/news/new-functionality-bluetooth-for-pico-w/ Now, with the release of version 1.5.1 of the C SDK, and the latest MicroPython build, your existing Pico W has gained the ability to communicate with Bluetooth and Bluetooth LE devices. |

... if you write the firmware to handle it. Finished it for you. :) Having it available in the SDK doesn't mean that it's practicable to include it. It was announced in February for C programming, IIRC, but hasn't been supported in Python until fairly recently.

As already posted, it's not really new news, but a critical issue is what's the RAM footprint? John |

From Arduino-Pico Documentation Release 3.3.0 Earle F. Philhower, III Jun 20, 2023 23.1 Enabling Bluetooth To enable Bluetooth (BT), use the Tools->IP/Bluetooth Stack menu. It requires around 80KB of flash and 20KB of RAM when enabled. Both Bluetooth Classic and BluetoothBLE are enabled in btstack_config.h. Gregor |

All RAM on the PicoMite is already allocated AFAIK. matherp will no doubt correct me on this if I'm wrong, but to get BT I suspect that you'd probably lose another flash slot and over 20kB of user RAM because RAM allocation may not be splittable where you expect it to be. I can't speak for others, but I'd consider that too much of a loss when it's so easy to add a separate BT module.

A BlueMite version could be possible. As I said before, it seems that you have to use a LINUX IDE to successfully compile the bluetooth stack. I tried by Windows and I failed with the simplest examples. Gregor |
