How to Create multiple BLE connection in Production?

[M.Hassan]

Hello Everyone!

I am working on a zephyr project based on nrf52832_mdk hardware. I have a code that transmits data over BLE. The BLE connection name is, let say zephyr-connect. Now the problem is that I have to use this device in production where multiple nrf52832_mdk hardware will be placed in the same place and different mobile will try to connect to them. if every hardware will broadcast BLE connnection with name zephyr-connect, how can we differentiate between the devices. Is there a way that every device will broadcast BLE connection with its mac address or any other technique to differentiate the name in each hardware?

You can enable the BT protocol stack to read the local MAC address before starting the broadcast, and then modify the name in the broadcast to add the first 3 bytes of the MAC address.
