8.16 Miscellaneous Commands
8.16.1 Get Security Mode
This command gets the current security mode of the module. Bluetooth v2.1 and newer devices cannot
disable security therefore only values 12 to 15 inclusive are valid. These values specify Simple Secure
Pairing with appropriate I/O capabilities.
Specifying a value of 0xFF means leave the mode as it is, but inform the host with regards to current
mode.
