Star connection between BLE Devices

[Om Patel]

I want to send Digital Microphone data from one device to the other two devices. So which BLE and micro-controller should I use for better performance? I am totally new to this and I need some help on coding too. So please let me know how can I start for the same.

The limiting factor is going to be the BLE link - not the microcontroller.

Remember that the specific design goal of BLE, as the name suggests, is Low Energy - not high-speed or high-volume data transfer.

To what, exactly?

Do you have prior experience with any other microcontroller(s)?

Do you have prior experience with any form of programming?

Do you have prior experience with electronics?

Do you have prior experience with communications; particularly, radio communications?

Hi,

It is a formidable task ahead of you, and even then due to some limitations in BLE it may not fly due to the latency and throughput of a BLE connection. I would not recommend to start on such a task unless you have a large team to help you.

Best regards,
Kenneth

I am new to Programming especially for this task i.e. one to many or Mesh connection.

We have a team to help me out but I want to know whether it is possible or not. Please let me know how I can proceed for this task. I need support on the programming side.

Thanks a lot for your support.

Regards,

So a key part of that team needs to be a competent embedded programmer (or programmers)!

As noted, that's mostly going to be down to the limitations of BLE - not the particular microcontroller.

So you need to spend some time researching the capabilities of BLE, and analysing whether they fit with the requirements of your project.
