Multi Serial Communication via RS232 interface
Promi-MSP can communicate with Promi-SDs up to 14 devices via RS232 interface, while
Promi-SD can be only used as 1:1 cable replacement.
Even though Promi-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 Promi-SD is buffered on Promi-MSP and retrieved
when corresponding Promi-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, Promi-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 Promi-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.
