We need to connect at the same time several mobile phones with the Android OS to a single device nrf51822 via BT in our upcoming project. According to information from the documentation and from discussions we discovered that this configuration is not possible. I would like to ask you whether there is any way to achieve the connection of simultaneous mobile phones in Central role to one nrf51822 unit in the Peripheral role. If not, it would be possible to order some adjustments of the S130 that allow many-to-one connection? How expensive would this modification be?
