Bluetooth module capable of slow data rate?

Wireless & IoT

Hi Guys,

I’m developing a remote weather station based on the PICAXE micro controller. I’m looking to use RF to get the data back to a PC for logging purposes.

The PICAXE can only talk serial at 4800bps (unless I overclock it with a higher frequency resonator, which I’d like to avoid). Is the bluetooth module capable of low data rates such as 2400-4800bps or does it require a minimum of 9600bps as the datasheet suggests?

Cheers for your help!!!

Get a copy of the AT command set for the bluetooth module and look at pages 13-14. It lets you specify a baud rate as low as 1200, surely it supports 4800 as well.

HTH
