Help Choosing a Bluetooth Module for use with an Arduino
May 19, 2021 2:58 PM
I am currently in the process of designing a portable bluetooth speaker and am in need of some guidance when it comes to choosing the right bluetooth module for the task.
I basically would like to be able to connect to a single bluetooth module in order to stream audio to the speaker,outputed from the modules DAC, and control addressable Led strips built into the speaker via an app using a UART serial connection at the same time.
Does this sound like something that is possible? If so, any recommendations for a module that is suitable for this application would be greatly appreciated!
I have found the "SparkFun Audio Bluetooth Breakout - RN-52" which to me, sounds like it would be perfect for the job. But I really am new to this so could be totally wrong! Plus, a big downside being that it is only bluetooth 3.0 and has no option for an external antenna so once inside a speaker cabinet, range might not be amazing.
Am I right in saying that as long as the module has Rx and Tx pins then I will be able to program it to do what I like? Or do only certain types of bluetooth chips allow you to do this?
Thanks in advance!

I have no experience with building my own Bluetooth Speaker ...
I did however found a few project which may be used as a guide for component selection.
Note: it seems some just use a USB Bluetooth dongle ...
Hope this gets you some ideas to select the right module. 😊
