Hello…
I’d like to build a Raspberry Pi with an audio input (double RCA would be great) then Bluetooth the music to a Bluetooth speaker.
We have media devices (Androids & Windows) with our software to play scheduled music. I’d like to have the sound (via 3.5 audio jack output & split to RCA) from the device then go into the Raspberry Pi then the Raspberry outputs the sound to a Bluetooth speaker.
I will have someone to work on the code for the Raspberry to recognise the incoming sound & output the sound via Bluetooth
In theory this sounds like it will work but will need to make sure I can get the hardware to make it possible
All help would be very much appreciated
thanks
Wendy
Hey Wendy,
Welcome Back!
One of the only compatible hats for a Pi that I can think of would be the Raspberry Pi Codec Zero that can take an audio input up to 1vRMS that should be compatible with most smart phones and laptops.
As for connecting the output to be a Bluetooth speaker, this should be capable of being done with the Pis internal Bluetooth chip, I have personally connected Bluetooth headsets to the Pi 4 Model B to use in a portable movie player/media device. It is capable of using that internal chip to output sound, though can be a bit buggy sometimes, I have found there are workarounds with it.

Thank You!
Buggy might not be great in commercial environments. I see you also have Mini Digital Bluetooth Amplifiers. I wonder if that would do the trick?
Is that something we might be able to create an APP to pair the bluetooth connection and control volume levels?
thanks

Hi @Wendy115847 - sounds like an interesting project! What constraints are we working around here?
have you considered attaching a USB Bluetooth adapter to the PC and just connecting to the bluetooth speaker directly?

HI Michael
I am now looking into multiple set ups. We can’t use the USB ports on the Androids. But yes that is another option too. There are also mini-amplifiers with bluetooth & bluetooth transmitters. I guess it’s trial & error. I thought using the Raspberry might be fun!
thanks for the input

Hey Wendy,
If you are looking to use a Bluetooth amplifier board, we have a great guide and project build using a Bluetooth amplifier board that may be of interest to you. If you are just looking to play sound out through them it should be something worthwhile having a look at.
Cheers,
Blayden
