I have seen work done other places to get audio streaming working over Bluetooth LE (hearing aids for example). Would it be possible to get BTLE audio streaming of any kind working on Espruino?

Don't know about the Nordic chips - the esp32 has had recent support for Bluetooth audio - nothing has been added on the espruino port yet.

You shouldn't need anything specific for Bluetooth LE audio in Espruino - you can just take the data and push it into a double-buffered Waveform class.

Having said that, the data transfer rates sending on 'standard' Bluetooth LE are really quite low (2.5kBytes/sec) so you're not going to be looking at anything that's very good quality.

Hopefully at some point soon we'll add support for the increased MTU sizes which will give the data transfer rates a big boost, and then it'll get a lot more sensible.

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
