How many devices can i connect?

[roger.k]

Hi. I'm using SDK12.2.0, S130 ver2.0.1, nRF51822AC. As I know SDK12.2.0 can conenct 8 peripherals at the same time when it is Central mode.

I want to use it as central and peripheral at the same time.

Q1. Is it possible to use central and peripheral at the same time? Q2. If possible, I want to connect just 1 central as peripheral. How many peripherals can i connect? 8 or 7?

I hope your reply.

Hi,

From the S130 SoftDevice Specifications:

Concurrent Central, Observer, Peripheral, and Broadcaster roles with up to eight concurrent connections along with one observer and one broadcaster

and

The SoftDevice can be configured with one connections as a Peripheral and up to eight connections as a Central. The SoftDevice supports running one Advertiser or Broadcaster and one Scanner or Observer concurrently with the BLE connections.

So, to answer your questions:

1. Yes, you can have central and periperal role at the same time
2. With one connection as peripheral, you can have 7 connections as central, max 8 connections in total.

Best regards,

Jørgen
