I built some auto-playing instruments with the mini solenoids and I’d like to send wireless microphone outputs to a common receiver/selector (the instruments are in different rooms). The stream has to be low latency (after some operations with CMOS op-amps).
I’m getting lost in the internet jungle… anyone has suggestions for a module with a breakout board that meets the following requirements?
- Bluetooth stereo audio module which allows AptX LL (standard 5v supply for either lion battery or direct usb).
- It can be configured as transmitter or receiver by flashing code.
- I want to upload the code containing the pairing information and establish a connection between transmitter and receiver modules when the devices turn on, without the intervention of smartphone or computer.
- I want to change the pairing only when selecting between 4 transmitters with a selector on the receiver device I’d like to build.
I’m also open to deal with normal Radio Frequency but, in case I have to go with RF, I’d like something more than the 10m range of the Adafruit Stereo FM Transmitter with the Si4713.
