an ESP32 requires an input signal to the ADC, preferably analog such as a sinewave or music etc. Of course, I could have simply misunderstood your question, in which case please accept my apologies. Perhaps, if you clarified exactly which parts you have identified as the 'source' of the rear channel(s), then someone may be able to help?Īnd as a last comment, particularly if it is necessary to have a Bluetooth source as I suggested above, I haven't any personal experience with I2S, but a quick look at Bill's ( excellent video and accompanying article suggested there is an entire 'infrastructure' of modules, software, etc to explore that is dediciated to audio. Equally, I haven't tried to do it, so I have no idea if there are any practical problems to overcome. Whether such a system exists commercially, I have no idea. (The receiver box you describe you want to build would fit this role.)

A Bluetooth receiver, that connects to the 'source', and converts it back to analog, and feeds it to an amplifier(s) and speaker(s).

A digitiser/Bluetooth 'source', that takes the audio stream of 1 or two channels, from (say) a 3.5mm jack socket of PC sound card, intended for a rear speaker connection, digitises the signal(s), and transmits it over a Bluetooth link.

However, I can imagine a system that consists of two parts. Whilst such descriptions can always be misleading for any number of reasons, such as new developments since they were posted, they did leave me wondering if what you were suggesting was 'possible' with standard equipment. I couldn't find any 'authorative' descriptions of how many audio channels Bluetooth can handle, but some descriptions clearly say that Bluetooth is limited to two channel. In particular, how/where does the ' analog audio source(rear output of sound card)' turn into a Bluetooth signal?ĭoes your computer have a sound card that transmits all of the front and rear channels as Bluetooth? So far at this point I can get the computer to recognize the receive module and send a signal to it but it always wants to send the front channels only.

What Im having trouble with is finding the proper code to load into the ESP32 to send a Bluetooth signal from an analog audio source ( rear output of sound card) to the receiving Bluetooth module. I think I understood the first part of your message, but this part confused me. Hi I am not the best person to advise on available libraries, but I also got confused about the description of what you are trying to do, and I wondered if a little clarification of the specification of what you are trying to do would help. If I turn off the computers Bluetooth and use a stand alone ESP32 unit, I think I can achieve my goal.ĭo any of yall have some good leads to some easy to use code for this idea? Much appreciated. Im trying to avoid running 20+ feet of wire from the computers sound card to the speaker set.

Plans are to install a 120VAC/5VDC phone charger inside the sub woofer case ( where all the power amps are for the speaker set) and have that power a Bluetooth 'reciever', the output of the 'reciever' will be wired directly to the audio input jack of the amp. Been working with the ESP32 and want to make it 'transmit' audio signal from the rear speaker connect of my sound card on my computer to a Bluetooth 'receiver' mounted inside the case of the 'rear speaker set'.
