I am new to BLE with my nRF51. I've got this example and I try to stop a RSSI scan when the device get all advertising data from the local device.
But when I try to add a loop for scanning the program just stop working nothing happens no scan at all. Maybe I put a loop the wrong places.
Then I try to compare MAC addr. with first one that the device read when MAC addr. matches program should stop scanning. Right now program
just stop/resume with Button 1 press.
I wonder is there any function or command to get only a single report of advertising data (Not the infinite loop)
