15. RI dependent Start-up Mode
16. Reset via BREAK
17. Append Bluetooth Address to Friendly Name
The UART_RI line can be configured as an input and on power up, its state can be used to force the
device into one of two modes, defining discoverability and connectability state. See description for
S Registers 565 to 569 inclusive for more details.
For example, the feature could allow a device to make an outgoing connection if RI is in one state,
and be ready for an incoming connection in the other.
The module can be reset by sending a BREAK signal. A BREAK signal exists when the module’s
UART_RX input is in a non-idle state (0v) for more than 125 milliseconds.
Ezurio Terminal provides a BREAK capability which can be used to reset a connected BTM device
by ticking and un-ticking the BRK field. See Figure 3.30.
If S Reg 593 is set to 1, then the last six hex digits of the Bluetooth address are automatically
appended to the friendly name. This allows multiple devices with the same name in a neighbourhood
to be differentiated.
