S-Register

S-registers contain 46 parameters of Promi-ESD. These are stored in flash

memory and sustained the values unless hardware reset is executed. The value

of S-register can be accessed and changed with ATS command by user. Some

S-registers not shown below are set to maximize the performance of Promi-

ESD. Thus it is not recommended to change these S-registers.

Change the value of S-register only in Standby status.

 S1: Force to Reconnect (default 1)

S1=0, Promi-ESD in Mode1 does not try reconnection when disconnected.

S1=1, Promi-ESD in Mode1 keeps trying reconnection when disconnected.

 S3: Stream UART Policy (default 0)

S3=0, the priority of UART streaming is throughput.

S3=1, the priority is latency, which minimizes the delay of data transmission.

This is useful in case of transmiting very small data quickly.

 S4: Enable Remote Name Query (default 1)

S4=0, Promi-ESD inquires only BD address. This speeds up the inquiry process.

S4=1, Promi-ESD inquire BD address, device name and class of device.

 S10: Enable SD Response (default 1)

S10=0, Promi-ESD does not send SD responses to host system.

S10=1, Promi-ESD send SD responses to host system.

 S11: Enable Escape (default 1)

S11=0, Promi-ESD does not allow escape sequence character. The operation

status of Connect cannot be changed to Standby. As Promi-ESD skips the

process detecting escape sequence character, the more efficient data

transmission is expected.

S11=1, Promi-ESD allow escape sequence character. Whenever it is needed,

the Connect status can be changed to Standby.

 S12: Clear Data Buffer When Disconnected (default 0)
