Hello Jan,

If you are applying the patch to the v1.4.0 stack as described in the wiki: processors.wiki.ti.com/.../SerialBLEbridge
then it should continuously advertise as connectable. Can you take a BLE sniffer trace?

Best wishes

The problem was stack size in IAR project. I changed it and now i can see it when iam using TI BLE Multitool app on my iphone. But only using this app, I still cant see it on other devices like laptop. Do you know why?

Do you mean you are using your laptop's native bluetooth functionality? This varies by laptop and some do not show Bluetooth Low Energy devices. Can you try this using the CC2540 Dongle and BTool as described in the Mini DK devlopers guide?

That is to be expected. You will not be able to discover BLE devices through the iPhone's Bluetooth settings. As long as you can discover them with multiTool, sensorTag, LightBlue, or any other BLE app, there is no issue. I have seen, at least in iOS 8.1.3, that after I connect to a BLE device I am then able to see it in the Bluetooth settings.
