Broadcast a message in central multilink application

Happy to help.

Sorry I was a bit unclear in my previous responses.

Good luck with your project. If you want 1:m communication, I would suggest looking at one of the Mesh protocols, i.e BLE Mesh.

Ok, so no. Thanks anyway ;)

Yes, I want to know if there is one command to send message from central device to all connected peripherals at the same time

Not sure if I understand the question.

You'll have to either advertise the data, which is not optimal for transfering data, and you have no possible ack. Or you have to send it separately to each connected device.

Let me rephrase the question:

Is there a way to broadcast a message as central (no peripheral) device and so without using the advertising?

Not sure what you mean by this. But your device can act as both a central and a peripheral. If you want to send a message to all devices, you either send it to them one by one, or you broadcast your data.

Maybe a BLE Mesh network is something that is suitable for your product?

I'm using nRF Connect SDK 2.3.0 .

Hi.

Thanks for your question.

Maybe you could add some information about which version of the SDK you are working with?

However, you can take a look at the Broadcaster sample.
