Hi Everyone,

I'm currently working on a project. I need help connecting my Pico to the smartphone module via Bluetooth, Please help me on which bluetooth module to use and if you can provide me any sample code for the Pico part.

Thank You

Hi,

You can wire up something like an HC-05 module (https://www.ebay.co.uk/itm/125085159709) and then connect to the Pico via Bluetooth UART connection. This is a bunch of info on doing it with the original Espruino board which even had a space on it: http://www.espruino.com/Bluetooth

However I'd strongly suggest that you look at one of the Espruino devices (like MDBT42 Breakout - http://www.espruino.com/MDBT42Q) that has bluetooth already on it - that would be so much easier to use. More compact, and it'd use a lot less power too

You need an app like this one to connect to your Bluetooth device.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.
