Appendix C: S-Register
S-registers contain the parameters for the Parani-BCD110V3. 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-BCD110V3. Thus it is not recommended to change these S-
registers.
Change the value of S-register only in Standby status and turn Parani-BCD110V3 off and on.
C.1. S1: Force to Reconnect (default 1)
S1=0, Parani-BCD110V3 in Mode1 does not try to reconnect when disconnected.
S1=1, Parani-BCD110V3 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-BCD110V3 sends the received data
immediately. When this value is 0, the Parani-BCD110V3 maximizes throughput, the Parani-
BCD110V3 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-BCD110V3 will query only the BD address. This speeds up the inquiry process.
S4=1, Parani-BCD110V3 will query the BD address, device name and class of device.
When this value is 1, Parani-BCD110V3 finds not only BD address but also friendly name. When this value
is 0, Parani-BCD110V3 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-BCD110V3 works in Low Power Mode or not. When this value
is 0, Parani-BCD110V3 works only in active power mode. When this value is 1, Parani-BCD110V3
will be in low power mode to save the power. Therefore, it takes a few seconds to wake the
Parani-BCD110V3 out of low power mode.
