6.3.26 AT+BTD*{Remove All Trusted Devices}
WARNING: This command is used to remove all devices from the list of trusted devices in the non-
volatile database. The software does not ask for confirmation.
WARNING: If you make an authenticated connection, the link key gets cached in the underlying stack. If
you subsequently delete the key using AT+BTD* and immediately request an authenticated
connection to the same device, then the connection will be established. To ensure this does
not happen, either send ATZ after the AT+BTD* OR send AT+BTD<bd_addr> for each item
in the trusted device database.
