hi all, our application connects both to mobile (ble) and speakers (br/edr) using bluez stack. our controller is configured as follows: current settings: powered connectable bondable ssp br/edr le secure-conn ever since IOS started supporting CTKD (cross-transport key derivation) at IOS13, pairing to mobile causes also link key distribution and brief br/edr connection follows the ble connection. I would like to avoid the link key distribution at the pairing stage. the only way I was able to achieve that is by disabling either secure-conn or ssp which is undesirable as disabling either of them block other functionality. what is the recommended approach? ** when br/edr is turned off we do not experience disconnections from mobile app running with IOS13. and vis versa. looking on HCI dump from mobile side the disconnections is initiated from mobile side, however the application is not the one initiating the disconnections. any advice is greatly appreciated Ordit
