SDK11.0.0 and 8 central connections

[Borkis]

Dear Nordic Engineers!

I am using the nRF51422 QFACA1 on custom boards and planning to migrate from SDK8.0.0 to SDK11.0.0

My application is using the S120 soft device and forms connection to 8 peripherals (s110)

According to spec of the s130 only 3 central connections are available.

However SDK11.0.0 example ble_app_multilink_central states "This example can be a central for up to 8 peripherals"

I would like to benefit from long term support, please confirm that 8 simultaneous connections support is available and will be maintained in a future.

What chip and/or development board are you using? I am using the nRF52 Preview board (PCA 10036). I learned the hard way that the PCA 10036 can't go beyond SDK 0.9.2. I spent days trying to debug code that never would have worked.

A Nordic engineer who helped me spot my problem agreed that the notice to upgrade to SDK 0.11.0 should be accompanied with a more prominent notice that certain hardware is not supported by the new SDK.

Thanks Ladasky, I refined my question

Hi,

I believe you are referring to S130 V1. SDK 11 is supposed to be used with the new S130 V2.0.1 which is capable of 8 concurrent connections. Refer to S130 SDS V2 Chapter 11.4 "BLE role Configuration":

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.
