Bluetooth support for Badger 2040W

Support
1

Hi.

I have a Badger 2040W and GitHub Universe 2024 Badger badge. I believe only the 2040W has wifi and bluetooth support, correct?

In any case, I’d love to add bluetooth functionality to my badge so it can get remote updates. Perhaps my heartrate, perhaps about something on my screen or a program, etc..

I sadly can’t find any samples about using bluetooth with the 2040w. Can someone help me out?

The 2040w is just a Pico-W glued to the back of the e-ink display. So every example you find for the Pico-W should work. But keep in mind that the bluetooth-stack comes at a cost: the firmware blob that needs to be loaded to memory. And that is also needed to update the display.

The Pico-SDK has BT-examples for C-programmers. Else have a look at this thread: BlueTooth on Pi Pico W - WORKING!
