Central & Peripheral baudrate

[Punit]

Is it compulsory to have same Baudrate on central & Preipheral side when using the NUS..?

I'm using Central @ 115200 & Peripheral @ 9600 [No flow control on either].

The data receive on the peripheral is not always correct...

No.

The interface to the hardware UART (including baud rate) is entirely independent of the Bluetooth service.

However, of course, if the baud rates are different, then your application is going to have to provide with buffering - possibly also flow control - to cope with the difference...

[awneil]

No, that's not true.

Just like in the old days of dial-up modems.

However, as noted, if the rates are different you could get "buffering" issues ...

But this has nothing to do with the NUS itself.
