Hello, I am currently working on prototyping a device and essentially the issue I am running into is that I need to be able to transmit the audio signal from the DFplayer to a wireless headset (Also being prototyped for the specific application I plan on using). I know how I can make this work simply using the DFplayer and a wired headset, but the main aspect I need to implement is wireless connection between the DFplayer and the headset. I have read many forums and searched through several parts and at this point I am just unsure what bluetooth module will be able to transmit the audio wirelessly. Any advice would be appreciated, as well as any suggestions on how I could take a different approach I could take towards transmitting a stored audio file wirelessly to a headset. Thanks!
the DFplayer does not give you the samples, it just plays out.
To be able to send audio through BT, it's not the common SPP profile that is used to emulate a serial port, you need an audio capable profile like A2DP or AVRCP, not all BT components support that.
you could read more about audio over BT in this SparkFun guide
