Thanks for your help!

Additionally to your answers the Enter the Multi NUS a simple wireless UART network article from a Nordic colleague really helped.

Best regards

I assume this should work out of the box, just run the necessary functions to start scanning, connectable advertising, and to initiate the connections. I think the BLE stack should handle everything for you then.

If it doesn't work, please get back to me and I'll try to get it working myself.

Just remember to set the following:

CONFIG_BT_MAX_CONN=22

It does not seem like 22 connections are supported if you use the SoftDevice Controller (only tested with 20 connections). However, it seems like it's supported if you use the Zephyr BLE Controller, where you're able to select up to 64 connections. I can ask internally to get more clarification on this if you would like.

Best regards,

Simon

Thank you for the answer.

This example doesn't really answer all my questions, actually the connection handling with the multi-role setup is the part where I struggle the most.

The Zephyr example Scan & Advertise demonstrates how to scan and advertise simultaneously. I can see the that the sample does not initiate any connections, please tell me if this sample is not suficcient and I will investigate more.

Best regards,
