I had try to use nRF connect to connect between nRF52840 Dongle and the bluetooth of application.
(I'm not sure the model of bluetooth of application.)
It's connected but not working and application showed "No device is detected".
The program use nrf library called MasterEmulator with MCP. But I search that it's for others model.
Can nRF52840 Dongle connect with Master Control Panel/Master Emulator? Thanks.
