CC2650EM-7ID-RD: SimpleBLECentral - Shows not all devices!

Hello,

I'm running the SimpleBLECentral example project on my CC2650 with Smartrf06. It's working fine, except for discovering and connecting. When I press the "UP" button, the discovery scan is started. Then It shows by "LEFT" click the results. I've set up two peripherals, one on another SmartRF06 and the other on my Smartphone. But the central only shows some random devices, not my peripherals. Also there are two ore more devices with address 00:00:00:00:00:00. When I try to connect to a random device with "valid" address, It starts connecting but this process never ends. OR it says failed, reason: 49(0x31) (0xCA on UART) but in error code list I can't find this error:

/*** Generic Status Return Values ***/
