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,<dst1>,<dst2>,… **
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.
