[Bluez-users] UART speed

[Bluez-users] UART speed

[Ronny L Nilsson]

Hi
I have a question about UART speeds.

I'm using a UART based device with CSR chipset and BCSP protocol. The 
module seem to use a speed of 115 200 bps by default but I would like 
to lower it. Do BCSP support speeds as low as e.g. 9600 bps? If yes, is 
there a tool for configuring the change? Perhaps a PSKEY?

Regards
/Ronny Nilsson

the pskey tool from bluez-utils can do the job, but be careful with it.
You can render your device useless with this tool. And setting the UART
speed to 9600 bps makes no sense at all, because the throughput will
decrease and besides for AT commands it becomes useless.
