nRF5340 dk(central) support concurrent (simultaneous) BLE connections

[Stjepan Brlecic]

Hi,

I use nRF5340 DK SDK 2.2.0. as Central and multiple iPhones as Peripheral.

I have a question about concurrent (simultaneous) BLE connections.

1. is it possible with nRF5340 DK in central mode to be connected to multiple peripheral devices at the same time?

If concurrent (simultaneous) BLE connections are possible

    2. how many devices, and what performance can be expected?

    3. Is there some example that can be used, like "central_multilink" but for nRF 5340 DK

 

Br,

Stjepan Brlečić.

I Stjepan, 
I don't see any reason central_multilink can't run on nRF5340. The only tricky part is that the nRF5340 has a separated network core. This require a separate build of the network core (the hci_rpmsg project)
What you need to do is to make an overlay for the hci_rpmsg child image. Please have a look at this. In the case the customer ask about multi link peripheral, so you need to set CONFIG_BT_CENTRAL=y instead of n. 

We support up to 20 concurrent links.
