Hi nordic team.
im devolep a keyboard using ncs sdk by nrf52840.frist step,i want to Implement a function that my keyboard can be connected to three Bluetooth hosts at different times.
1.Firstly, the keyboard can be connected to three host devices in sequence.
2.The keyboard can freely switch and connect to different hosts through different keys.
3.The keyboard can delete the binding with any host through buttons.
i see some article that the ble_bond module can Switch the connection and earse bond,but i dont know how to connect a new host.my opration as fllow:
1.creat a new application by copy application nrf_desktop.
2.modify the prj.conf

3.delet the button 1 report.
4.build and program it .
5.connect the device by my pc.
6.click button 1,but the board no any reaction,it also connet the pc.
so if the ble_bond module cant support the new advertising,and i need start it by ble_adv module?the ble_bond module can only process erase bond and select bonded host?
