https://devzone.nordicsemi.com/f/nordic-q-a/7652/scanning-nrf51-dk-by-evothings-client-app-andriodHi Evothings Client is not scanning my NRF51-DK using HTC Desire 610 android mobile. When I plugged nRF51-DK to my computer , it shows power On and my device manager shows JLINK (usb:jlink) I have connection to my computer.
