Hi. I try run "ble_app_hids_mouse" example from nRF5_SDK_11.0.0 in nrf51422 (nrf51 dongle). Previously i ran this example in nrf52 (nrf52 DK, s132 SoftDevice), and all worked normally (windows 10 detect bluetooth device as mouse HID, and successful connect it). In case of nrf51422 (s130 SoftDevice), windows 10 detect bluetooth device as mouse HID, but cant correct connect it. If Windows connect, install "Battery device" driver and show it not "Pair", like in case of nrf52, but "connected". But usually Windows cant connect my device. Thanks for the help
