Appendix C: S-Register
S-registers contain 52 parameters for the Parani-BCDx10. These are stored in flash memory and the
values will be saved unless hardware reset is executed. The value of S-register can be accessed and
changed with ATS command. Some S-registers not shown below are set to maximize the performance
of Parani-BCDx10. Thus it is not recommended to change these S-registers.
Change the value of S-register only in Standby status. Turn Parani-BCDx10 off and on.
C.1. S1: Force to Reconnect (default 1)
S1=0, Parani-BCDx10 in Mode1 does not try to reconnect when disconnected.
S1=1, Parani-BCDx10 in Mode1 keeps trying to reconnect when disconnected.
C.2. 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
transmitting very small data quickly.
When this value is 1, in order to minimize latency, Parani-BCDx10 sends the received data
immediately. When this value is 0, the Parani-BCDx10 maximizes throughput, the Parani-BCDx10
stores received data for a short time and sends a large data packet. If the packet length is less than
100 bytes, having latency being the priority is recommended. If the packet length is more than 100
bytes, having throughput as the priority is recommended. Also, if you want to use high baud rate,
throughput priority will be more effective. Just for reference, the buffer length for receiving data is 2
Kbytes.
C.3. S4: Enable Remote Name Query (default 1)
S4=0, Parani-BCDx10 will query only the BD address. This speeds up the inquiry process.
S4=1, Parani-BCDx10 will query the BD address, device name and class of device.
When this value is 1, Parani-BCDx10 finds not only BD address but also friendly name. When this
value is 0, Parani-BCDx10 finds only BD address. When set to 0 this will make queries much faster.
When using the pairing button, finding friendly name will be omitted automatically.
C.4. S6: Enable Low Power Mode (default 0)
S6=0, deactivate Low Power Mode.
S6=1, activate Low Power Mode.
This value decides whether Parani-BCDx10 works in Low Power Mode or not. When this value is 0,
Parani-BCDx10 works only in active power mode. When this value is 1, Parani-BCDx10 will be in low
power mode to save the power. Therefore, it takes a few seconds to wake the Parani-BCDx10 out of
low power mode.
C.5. S10: Enable Response Message (default 1)
S10=0, Parani-BCDx10 does not send response messages to the host system.
S10=1, Parani-BCDx10 sends response messages to host system.
This value decides whether Parani-BCDx10 sends response messages such as OK, ERROR,
CONNECT, DISCONNECT or not. When this value is 0, Parani-BCDx10 will not send any response
messages. If the response messages conflicts with your host programs or devices that is connected to
Parani-BCDx10, change this value to 0.
C.6. S11: Enable Escape (default 1)
S11=0, Parani-BCDx10 does not allow escape sequence characters. The operation status of Connect
