Thanks for the suggestion, but I'm still curious about how to do this with a pico.

If you're not tied to the pi pico you might be better served with an ESP32. It has Bluetooth built in and probably better documentation at this stage. Here's one example project:

[You can buy Bluetooth modules](https://www.amazon.com/gp/product/B01G9KSAF6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) to put in your projects.  Don't ask me how to program it, though.

Hi, I want to create a Raspberry Pi Pico powered device that would act as a bluetooth game controller. I know that the Pico is able to emulate HID devices via USB, but what about bluetooth? Does this depend on the kind of bluetooth module I get? Which bluetooth module would you suggest to buy to accomplish this task?

Mind you, I'm not very skilled with electronics, and I'm still learning.

Emulate a bluetooth controller?
