I have programmed nrf51-dk with mbed as well as Kiel but there is a difference

[Ajaysaini58]

I have programmed nrf51-dk with an example code available at mbed platform,everything works fine except that the ble is visible even if we open bluetooth menu.It is scanned and in the bluetooth scan list. I had read somewhere that to scan a ble device you need Ble scanning app. Whereas when an example is programmed via uVision Kiel ,in that case i have to download the NRF toolbox app to scan the device.

Hi Ajaysaini,

I don't think it's about Keil or Mbed, it's more about which services' UUID you put in the advertising packet. Usually, in bluetooth menu you will be able to see HID and audio devices, (sometimes heart rate on some Android device). There is a chance that the mbed example advertises with HIDs service when the example flashed with KEIL doesn't.

Thanks @HungBui. But i have used same UUID in both Kiel and mbed.

@Ajaysaini: Please let me know your central device and the OS version. Also please take screenshot of the advertising packets for both cases.
