Max. no. of concurrent BLE connections

Hi there,

What is the max. no. of concurrent BLE connections on IOS when it's acting as a Central?

While we're able to discover more than 10 devices, when we try to connect to the eleventh device, we never got the peripheralDidConnect call back.  Then if we disconnect any of the previous 10 devices, we couldn't connect to new ones any more.  From then on, Bluetooth seems to misbehave and might even restart (evident by the change of Bluetooth status from CBCentralManagerStatePoweredOn to CBCentralManagerStatePoweredOff).   And this limit seems to be systemwide.

Regards,

Anton
