Bluetooth Module with Teensy 3.2/3.6

[4bdu1]

Hello all, pretty new user wanting to try Teensy for an audio project using bluetooth connection to an android app. So basically I would like to take signals, do some processing on the teensy 3.2/3.6 then after transmit in real time the processed audio via bluetooth to the android app to visualize and listen to the processed sound. I was looking at possible bluetooth modules to use with the teensy and came across BC127 bluetooth module. This looks like a promising candidate and wanted to find out if anyone has used it with the teensy before or other alternatives for the bluetooth module that fits the teensy 3.2/3.6 (small fitting size preferrably). I'm hoping to use it two way though, to send commands from the mobile app and also transmit processed audio from the teensy. Any guide would be really appreciated.

Thanks in advance.

The HC05 is known working with the Teensy and it is very small: https://www.itead.cc/wireless/bluet...port-bluetooth-module-master-slave-hc-05.html

Besides of that, it operates at 3.3V, thus no level conversion issues or whatever. Since it behaves like a serial connection, just without cable, it is totally transparent and you might write your code as if you'd send and receive data and/or commands over a classic UART.

Ok. So will it be able to serve the purpose of transmitting the processed audio data real time? I'm considering signals with frequencies up to 20kHz
