Multi Serial Communication via RS232 interface

Parani-MSP can communicate with Parani-SDs up to 14 devices via RS232 interface, while

Parani-SD can be only used as 1:1 cable replacement.

Even though Parani-MSP supports multiple serial connections, because RS232 interface is

inherently 1:1 communication protocol, user should communicate with serial devices

sequentially. Data coming from non-selected Parani-SD is buffered on Parani-MSP and

retrieved when corresponding Parani-SD is selected by ATO command.

If link is lost with currently selected device, one of connected devices will be selected arbitrarily.

Accepting new incoming connection

When incoming connection is established in command mode, Parani-MSP responds with

CONNECT message and enters to online mode.

When incoming connection is established in online mode, CONNECT message is not printed

and selected device with which Parani-MSP communicates won’t be changed.

You can check out all connected devices by AT+BTCONN? command in command mode.

Disconnecting device

You can disconnect Bluetooth device by ATH command in command mode. With specified

device address, any connected device, selected or not, can be disconnected.
