Hi all.

I have a project where I need 1 BLE Central will connect with maximum 30 BLE Peripheral. Is it possible?

Thanks in advance.

Regards.

Hi,

Currently we don't have any softdevices that can handle connection to 30 peripherals. We recently released an alpha version of the S132 v4 softdevice, which introduce support for 20 links in total with freely selectable role (Central/Peripheral) for each link. The currently latest production ready softdevice, S132 v3.1.0, support concurrent central, observer, peripheral, and broadcaster roles with up to eight concurrent connections along with one Observer and one Broadcaster.

You have to remember that the radio time have to be divided between all the links, leaving a small portion of time for each link with such a large number of connections.

Best regards,

Jørgen
