I am trying to setup a nRF51422 Development Kit (PCA10028) v1.1.0 board with ble-sniffer_win_1.0.1 sniffer. I programmed the Dev board with firmware version ble-sniffer_nRF51822_1.0.1_1111_Sniffer.hex came with NRF-sniffer 1.0.1 release. After I programmed the Dev board with FW via nRFgo studio, and I noticed all 4 LEDs on the Dev board stayed ON, and Sniffer software tools can't discover the Dev board via COM port. However I do see JLink CDC port under device manager.
Can anyone help me out with this issue?
