Repeater-to-Repeater connection (Multi-level repeater) is not allowed. Parani-MSP may operate
as “Station MSP” while it is either Server/Client/Vertex/Serial Hub/RS232 mode.
All you need to configure in Repeater is only Bluetooth device address of Station MSP and
repeater doesn’t need to have any network connectivity (Just power-supply).
Note:
When using repeater, overall data throughput can be lowered.
Multi-level repeater is not allowed.

4.5 Serial Hub Mode
In Serial Hub Mode, Parani-MSP relays data communication between Bluetooth devices. With
Parani-SD only 1:1 cable replacement is possible, however, incorporating Parani-MSP multiple
Parani-SDs can communicate each other, 1:N multi-serial with Parani-SD.
In Serial Hub mode, Parani-MSP handles data according to Route Table, which shows which
data frame should go where. Route Table needs to be configured in advance using Parani-MSP
software.
In-Band Command
In addition to Route Table, user can specify the destination of the frame they send by inserting
extra frame called ‘In-Band Command’. Inserted frame will be processed by Parani-MSP and
not be transferred to destination device.
**INI+DST,,,…**
where, dstX means Bluetooth address of destination.
ex)
**INI+DST,00:0B:53:10:00:8A**Hello**INI+DST,00:0B:53:10:00:8B,00:0B:53:10:00:8C**Bluet
ooth
For example, if you send preceding frame to Parani-SD, 00:0B:53:10:00:8A device will receive
‘Hello’ and the other devices will get ‘Bluetooth’ as below figure.
All Parani-SD should be connected to Parani-MSP.

“Hello”
“Bluetooth”
00:0B:53:10:00:8A
00:0B:53:10:00:8B
“Bluetooth”
00:0B:53:10:00:8C
As Serial Hub mode does not need TCP/IP network connectivity, users do not need to configure
network settings. Only power-supply needed.
4.6 RS232 mode
Multi-drop
If users set Parani-MSP to RS232 mode, Parani-MSP may act as 1:N multi-serial port by its
RS232 port. In RS232 mode, Parani-MSP will send data to external serial port, not via Ethernet
network.
In RS232 mode, Parani-MSP handles data in Multi-drop way, so data written to RS232 interface
of Parani-MSP will be delivered to all of connected Bluetooth devices. So, in RS232 mode,
“Polling” method- a master device schedules slave devices- is recommended to use.
Users may configure Serial settings in configuration console or Advance configuration dialog of
Parani-MSP software.

As default, RS232 interface of Parani-MSP is configured for configuration console. In order to
use RS232 interface for the data communication purpose, user needs to change the Console
switch to data mode. Changes will be effective after power-cycling of Parani-MSP. Please restart
Parani-MSP.
AT Commands
AT command is very familiar with the legacy serial application developers. So, AT command
interface of Parani-SD eases a lot of efforts to develop their own application from developers.
So does Parani-MSP. Moreover, AT commands of Parani-MSP are so similar to one of ParaniSD that developers who have experiences with Parani-SD can make use of multi-serial
functionality in no time.
By default, AT command parser is disabled. You can enable AT command feature on
configuration console as below.

5. Control Commands
Parani-MSP is configurable and controllable by Control commands through control TCP
port. Prom-MSP software is the GUI version of Control commands for easy use by customers.
As all of the control commands, in Parani-MSP software, are listed in the bottom window, it
gives users insight how each commands work.
Using control TCP port, users can make their own application control Parani-MSP by
themselves. This means users do not need to equip expensive Bluetooth development kit but
may develop Bluetooth solution to meet each needs by simple commands. Parani-MSP™ is
cost-effective and time-saving solution for users.
By using telnet program, users may use Control commands easily. Rich-featured telnet
software like “PuTTY” can be also useful.

connected to Parani-MSP, port number will be assigned automatically by
Parani-MSP. Users may check the port numbers used by LIST command.
Ex.:
PORT
+OK PORT 5000
PORT 6000
+OK PORT 6000
BIND  
A static port number may be assigned to a designated Bluetooth device
using BIND command. A Bluetooth device can be specified by either
friendly name or Bluetooth address.
Response:
Ex.:
+OK index|name|bdaddr|port
BIND 00:0B:53:00:00:01 8000
+OK
BIND Parani-SD 8001
+OK
BIND
0||00:0B:53:00:00:01|8000
1|Parani-SD||8000
+OK
RELE 
If users do not need to use a bound port number, RELE command can be
used to release the port number.
Ex.:
RELE 8000
+OK
PRSV 
A TCP data port is opened as a Bluetooth connection is made. So, when
Bluetooth connection is closed, the corresponding TCP port is also closed.
If this behavior interferes with your usage scenario, this option will help.
When this option is enabled, TCP connection remains regardless of
Bluetooth connection. Users do not need to make TCP connection each
time whenever Bluetooth connection is closed for a while.
Ex.:
PRSV on
+OK
