Im using bluesmirf, it works at 115200 but i want to change it to 9600 and i get no responce at +++ on the windows hyperterminal. what can i do?!?!?!??!?!?!?!?!?!?!?
Be sure to check the reference manual. I just recently got one of the “new” BlueSMIRF Firefly modules and got it running with Arduino Decimillia. There is a window of time, defaults to 60 seconds I think, when you can connect with the Command Identifier $$$ (three dollar signs). If you are connected via HyperTerminal in Windows XP, you immediately get a response of CMD back. Then you can enter a D - (dee minus) to display basic settings, including baud rate. It should be defaulted to 9600 baud. You can change this and store it to memory so it will survive power down by using the command: su,96. Then do another D - to check it. Some of the earlier posts on this thread say to use 115,200K for baud rate and None for Flow Control. I did not get my Hyperterminal communicating with BlueSMIRF until I changed Flow Control to HARDWARE.
I found that you can pass characters from Hyperterminal while in Command Mode ($$$). The string sequence is P, <some char(s)>. This will pass characters up to a CR/LF and you can use it to test a sketch on the Arduino.
I’ll try to write up a more extensive report for the forum when I get some time.
