Hi,
- Our project is 2D-3D mouse. we are using nordic "ble_hid_mouse" application with some required changes for our application.
- SDK we are using is 15.3
ISSUES
The problem we are facing .If we connected our mouse(peripheral) and with a pc (central) you known that bonding information of mouse will store on pc and vise versa .
Suppose if we remove the our device (mouse) from the pc device list .Bonding information from pc(central side) will delete. So if we try to connect the our device(peripheral) again to the same pc driver error will shown and the connection will not establish .These is because our device contains the bonding information of pc but pc has not. If we delete the bond information from our device too then there is no issue.
In the nordic nrf-Mouse there method for deleting the bond information from nrf52832 side is by pressing a button manually . But in our case its not applicable .We need to delete the bond information from nrf52832 side automatically if the central delete the bond .
So we find-out a solution for these by referring https://devzone.nordicsemi.com/f/nordic-q-a/9506/bond-deletion-notification this nordic ticket. Please look the marked portion of screen shot
we are following the first scenario.
So based on these ticket .After the central(pc) and peripheral( our mouse) connected and also if the central sends pairing request and the peripheral application receive the BLE_GAP_EVT_SEC_PARAMS_REQUEST event we deleting the bonding information from nrf52832.Look the screen shot below.
It is an effective way but it showing some issue if we connected on multiple pc without removing it.
WE NEED
In the above code(screen shot) before deleting the bond information we need to check list of bonded device in peripheral(nrf52832) and if the central address is already present in bonded device list then only we need to delete the specific bond from nrf52832 .
Is there any way for thsese.
Which function is used to the list of the read address bonded device from nrf52832.
which are the function to get the address of the central device.
Please reply as soon as possible.
