Cannot change the DFR Bluetooth Bee BAUD RATE ..
kolai 2012-02-24 21:26:12 4717 Views5 Replies Good day guys,
I wanted to change by Bluetooth V3's Baud rate to 115200, I'm using DFR Xbee adapter, I followed the instructions on the Wiki.
When I entered "AT" the reply was OK.
But when I tried "AT+BAUD8"(like what was instructed on the wiki) the reply was ERROR:(0).
Please help I really want to change the BAUD rate.. Thanks

Yes, I think it's ok. Generally speaking , the stop bit and the parity bit are not necessary. Lauren

Lauren 2012-02-25 04:18:37 Param1: baud rate (bits/s)
Param2: stop bit
0- 1 bit
1- 2 bits
Param3: parity bit
0- None
1- Odd
2- Even
Default: 9600,0,0
1- This is the information about the Bluetooth V3 module from the datasheet.
2- The "/r/n" is ASCII character. It means "Carriage return/new line".When you are using the Arduino Serial monitor, choose the "Both NL & CR",then the command'll be transmitted with the "\r\n"(HEX: 0x0D 0x0A).

One question, what are the numbers 1 and 2 for???
and the /r /n
Thanks it worked kolai

kolai 2012-02-24 22:43:43 Hello,
Example: Set serial port parameters to 115200, 2 bits stop bit, and even parity
AT+UART=115200, 1,2 \r\n
OK
AT+UART?
+UART:115200,1,2
OK
Try this~ ??? Lauren
