After once BLE Initialize and authentication set by fixed pairing key as "123456" then can we change again pairing key to "123678" by using this API "Aci_Gap_Set_Auth_Requirement()".
Means BLE will disconnected and I will configure its authentication fixed pairing key with other value during run time of my application. To ensure security as fixed pairing "123456" can known by unknown user also and he will connect to device easily but if I will change pairing key to some other value (whatever user wants of 6 digit) then unknown user will not easily connect to device which will secure my device.
