4.5 Serial Hub Mode

In Serial Hub Mode, Promi-MSP relays data communication between Bluetooth devices. With

Promi-SD only 1:1 cable replacement is possible, however, incorporating Promi-MSP multiple

Promi-SDs can communicate each other, 1:N multi-serial with Promi-SD.

In Serial Hub mode, Promi-MSP handles data according to Route Table, which shows which

data frame should go where. Route Table needs to be configured in advance using Promi-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 Promi-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 Promi-SD, 00:0B:53:10:00:8A device will receive

‘Hello’and the other devices will get ‘Bluetooth’as below figure.

All Promi-SD should be connected to Promi-MSP.
