Hi,
I am very new to BlueTooth technology. Currently i'm testing the nRF51822 evaluation kit to see if the BLE module can be used for a specific project. I've tried several Keil example project templates as pointed out in the evaluation kit documentation. The question that popped up during testing is why can't a smartphone find the advertisements sent by the evaluation board in the heart rate monitor template, for example(tested several phones including Lumia 720, nexus 5 and galaxy S4).
Initial examination of the code didn't find any restrictions as to why the dongle sees the broadcast, but a smartphone scan cannot. Am i misunderstanding some principle on which Bluetooth software stack works? Does the phone require custom software with a reference to the nRF51822 device?
