RE: connect mulit peripherals with one central

Hi, Simonr!

[quote userid="75734" url="~/f/nordic-q-a/78549/connect-mulit-peripherals-with-one-central/324801#324801"]The UUID will be the same for all NUS services[/quote]

In other words, if each have the same service, UUID is the same, right?

I thought UUID was the ID for device identification, so I thought that UUID is different for every device, even though the functions of the devices were the same.

But now I understand clearly! Thank you :)

I think you're mixing up DEVICE ID (that's preprogrammed in each device FICR area of Flash) and the UUIDs that are used by a BLE application to identify services and characteristics in a BLE connection.

1. The UUID will be the same for all NUS services for example, but these devices will have different Device IDs. I don't think there's a specific filter using Device IDs, but you can use part of the device ID as the name if you'd like, or a filter for the service UUIDs you're planning on using.

2. I hope the explanation above makes this clear.

3. The BLE Multi-Link example shows how one central can be connected to and maintain several peripheral connections at the same time.

Best regards,

Simon
