I agree, from a data throughput point of view, there is no need for higher baudrates.
My concern is more about connectivity than transfer rates.
There certainly are devices where a user/developer has no control over the baudrates of the serial port. So even if an application doesn't need high data transfer rates, it won't be able to talk to such a device, if it has a higher baudrate than the ones configurable by BLEBee.
At the moment, i'm developing an iOS App for configuring an Arduino based MultiWii
The MultiWii sketch defaults to a 115200 baud serial port, since its main purpose is to be connected to a desktop GUI over an FTDI-USB adapter. While the sketch can be adapted and the GUI configured to use a different baudrate, I still would prefer to suggest a solution with no additional configuration complexity to future users of my app. (I've already evaluated the BLE Mini
from ReadBearLab, but its baudrate is hardcoded in the firmware)
Thank you for the infos about the Bluegiga SDK.
ps: I'm sorry to annoy you with this topic, but a search on the forum didn't show up anything on it.
