Hacking Question Could a CFW add Bluetooth Audio support?

[McHaggis]

Are any of the CFW devs looking into this? According to some sources, the Switch's Bluetooth chip should support it:

It also occurred to me that the Switch's OS may already support Bluetooth Audio, and a CFW dev may just need to build in a method to pair a device that isn't a controller (which could also mean 3rd party controllers). It's true that Nintendo may have omitted support for Bluetooth audio for practical reasons (lag or interference with the Joy Cons), but it's equally possible they wanted to keep licensing costs down.

For anyone that's interested, you can buy a bluetoth audio adapter like the Creative BT-W2 (there's also the recent Genki adapter Kickstarter), but these have their drawbacks, such as requiring an adapter, preventing simultaneous charging or only allowing a single connection.

This could be done via a hardmod, im looking into it.

Maybe we could implement a bluetooth transmitter to that payload injector shaped like a gamecard

Uhm, the gamecardridge itself is basicly "just" a fancy place to store the rcm jig and the injector.
I'm thinking about a internal hardmod. You's need access to a button on the rear side tho.

It has been done. I have been looking into the parts in order to combine the function of my trinket and a bluetooth audio adapter. Also thinking about the usb c dongle that is coming out later this year (kickstarter). In my psp days I used to buy them with broken UMD drives and put bluetooth adapters there and microphones behind the faceplates. Im not putting much thought into it because when Im done Nintendo will enable it in the OS

Bluetooth Driver Services on SwitchBrew

There are commands here like StartDiscovery and CreateBond. Have any devs played around with this? I haven't done anything in C++ for years, but if someone could give me a hand with minimum compilable source code to use these commands then I could test at some point during the next few weeks.

It works on Linux, so the chip support it.

It is theoretically achievable however I wonder what bandwidth the joycons take up on the Bluetooth side. Would have been naive of Nintendo not to include this if it was possible as it's becoming the norm in tech.

Well that's not really an argument, sadly, since Nintendo doesn't do/implement PLENTY of things that are already a norm in tech (in some cases, a really old norm)

Lakka does Bluetooth Audio.

 

[Maximize0987]

hopefully they can work on bringing it to horizon

Would be awesome. In the meantime, I use this:

Doesn't lakka also require the joycons to be physically attached? I.e not both the joycons and wireless Bluetooth are active at the same time?

Edit: can't spell apparently!

I'd imagine this can probably be achieved with something like a kip module. Lakka has bluetooth audio working, so we already know that the hardware can support it.

Someone also made a pretty cool kip module that plays background music on the home menu. I can't see why this wouldn't be possible, but nobody has taken the time to do it.

This would be nice to know. I know that there can be different Bluetooth profiles (stacks?). For example, I have bt on my pc and I’m using a Magic Mouse and beats wireless headphones connected to it. I then paired my PS3 controller to the same bt device in my pc. The drivers had to be overwritten and I lost connection on my mouse and headphones. I could not re-pair them without uninstalling the drivers for my PS3 controller. iOS does this in a similar fashion.

Glad to hear Lakka supports Bluetooth Audio. I still wonder if Nintendo might be using generic BT code and all we need to do is find a way to pair.

Yeah but the downside with the dongles is they require an adapter in handheld mode and you can't charge while using them. I'm looking at getting a Creative BT-W2, they're about the same price but lower profile so a little bit better. I was going to back the Genki Kickstarter but everything included with shipping would have been over £50. More than I want to spend for convenience on the occasional plane/train journey.
