Hi,

Please have a look at the Experimental: BLE Multiperipheral Application Example and the BLE Multi-link Example in the SDK.

[EDIT 16.10.2017]: Attached modified example from multi-link central example to support connection to multiperipheral example: main.c

Best regards,

Jørgen

What you are experiencing is most likely due to this note in the documentation of the ble_multiperipheral example:

Note that you can also use the BLE Multi-link Example as Central. However, the multi-link example accepts all peripheral connections, so the Peripheral will connect four times to the same Central. As a result, you will see four indications for each event.

You will have to modify the multi-link cental example to check if the address found in the advertising packet is the same as the one of an already connected device. I have attached a modified version of the multi-link central example from SDK 14 that should support connection to multiple examples running the multiperipheral example, in my above answer.
