Hi,
I'm using nRF dev kit with Softdevice 1.0.0.3.alpha. The device shows advertising state at LED1 as it should, however i can't detect "Nordic_UART" via nRF Master Control...
Is the advertising interval between two packets P1 and P2 defined as:
Interval = P2_start - P1_stop (time between packets)
or
Interval = P2_start - P1_start (time...
