How many connections with nRF51 in peripheral role?

[Reiner]

Is it possible to establish and hold more than one connection in peripheral role? Is it possible to send advertisements simultaneously?

Hi,

The nRF51 series can only support one connection in the peripheral mode. In central mode, up to 8 connections is supported. If you want multiple connections as peripheral, you need to upgrade to nRF52832, which support up to 20 concurrent connections in total.

The devices are capable of doing non-connectable advertising during connection. Note that the Bluetooth specifications limits the advertising interval in this mode to 100 ms minimum.

Best regards,

Jørgen
