Bluetooth mate - Buadrate Setting

Wireless & IoT
1

Hello;

I have Blutetooth mate which I want to connect it to IMU with baud rate of 38400.

First I just change Bluetooth baud rate throgh the device manager COM port. and also through hyper terminal or Bray program I changed the baud rate to 38400.

I receive unreadable number.

I found I have to change the baud rate with command for Bluetooth.

I found this data sheet:

http://www.sparkfun.com/datasheets/Wire … 1_rev2.PDF

here said if you want to go to command mode use +++. But in my case with $$$ i could go to command mode. but what ever I typed the answer is “?”

I used this command o change the baud rate: ATSW20,157,0,0,1 .

But Nothing was changed.

Then from another website:

http://www.robotshop.ca/content/PDF/rn- … -09358.pdf

I used: U,38.4K,N to change the baud rate it gave me B-Err.

I have two questions:

1- Do you have any Idea why is the number unreadable? am I in the correcr way?

2- What is the command for changing the baud rate for bluetooth mate (Sku:09358)

Thanks in advances;
