Bluetooth stereo module v3.0 make the sound like "Bluetooth device is connected"

I want to make a project in which

I want to play music form smart phone inside the robo car.
Operate the robotic car(Motors) from mobile application.

Challange: -

Is there is any Bluetooth module which can communicate with robot car and play music at the same time.
I had use two separate module HC05 for controlling the motor and Bluetooth V3.0 stereo module for playing the music. When the power is on " V3.0 stereo module" make sound like " Bluetooth device is connected or Bluetooth device is ready to pair.

Can this this voice can be removed or is there is module readily available where we can remove this voice and communicate with the microcontroller at the same time?

Hi,

This doesn't sound like a very top-priority key feature for your project. I'd suggest, build your project, make it do the main things (music/motors) and once you've done that, you will be able to just extend your project to mute out the audio, by using the same system that you're using to control the motors, prior to enabling the music channel.

There are many other solutions, but you'll gain the experience by just trying, In this case, I think you can extend and modify once you have the rest working. This approach doesn't always work, but in this case it likely will.

Hi Shabaz,

Thanks for the reply

My target is that to remove the annoying voice when the power is on.

How can we remove it?

You'll have to look into modifying the firmware. It used to be more often seen for CSR BlueCore-based devices, but that scene is now relatively quiet and the tools unsupported. You'll need to do your own research as it is very much chipset-specific.

Does the music need to come through Bluetooth? Could you use an onboard MP3 player instead?
