I’m building my tritrak system and I’m testing all the sub units (sensors, bluetooth…) for good operation before I put them together.
I came across a tutorial lynxmotion.com/images/html/build117.htm
that shows how to connect the bluesmirf.
Step 11 states that in order to enter the configuration setup of the blue smirf you have to type +++
This is not the case for my bluesmirf gold module (blue antenna).
It seems that this module requires something different so you can access the configuration menu. It requires $$$ instead of +++.
When you apply power to the bluesmirf gold, it gives you a 60 second window that will permit you to type $$$ in order to access the configuration setup. If this 60 sec. window closes then the bluesmirf does not accept the $$$ key entry and will not enter the configuration setup.
I just though I would write this down to maybe help someone that is trying to enter the config. menu of the bluesmirf gold and cannot.
May a tip can also be included in the tutorial shown above.
Hi Alan
I got it from here sparkfun.com/commerce/produc … cts_id=582.
The bluesmirf gold is the same as the WRL-00582 pictured in the tutorial
Actually, I needed to enter the setup menu so I can change the baud rate down to 9600. I’ll try it out with slower speeds at first and then increase the speed and see how it goes.
OK, All I can see is that it has an on-board antenna. I ran my last one at 115K, so no setup. How about the setup under Device Manager? Can it set up the modem?
I’ll have to give that some thought. I’ve just re-written an BasicMicro program (MBasic) to use the hardware ports, and from experiments last Saturday, I wasn’t able to run an '877 PIC (10 Mhz clock) at 115K. Didn’t have much time to play with it. I run PICs all the time at 115K, so I’m not sure what’s going on. I also want to run a BasicAtom with Hardware (USART), instead of the bit-banged port. This should allow the COMS to run in the background.
I’m hoping to avoid having to change the BAUD rate of the modem every time it is powered up.
You do not need to change the baud rate every time the BT modem is powered up. If you set it to a specific rate it will stay that way until you change it again, even if you remove the power.
We went through hell with that tutorial at first. Sparkfun kept changing stuff almost monthly for a while. Are you relatively certain everything is accurate except the +++'s?
Looking forward to seeing the TriTrack when you have it going.
I had some confusion setting up my BlueSmirf Gold also. My soultion was default time outs. No change to Smirf and jumpers set to 115200 baud. Once i had the tx/rx wires on correctly
I don’t seem to be able to get the modem to go into configuration mode, but i’m @ hi speed so don’t care.
From what I see, the complete command set has changed. I got my info from this sparkfun.com/datasheets/Wire … oth-um.pdf
For example, with the module that I have, you have to do the following in order to change the baudrate.
Power up the blue smirf (Red led=blinks)
Establish connection using hyperterminal (Red led=OFF, Green led=ON)
type $$$ (the bluesmirf reports back with “CMD” (Red led=blinks rapidly - Green led=ON)
now you are in the configuration menu
type SU,11 to change baud rate to 115K and the bluesmirf reports “AOK” (see pdf file for other baud rate settings)
To exit the configuration menu type — (three minus signs) and the blue smirf reports “END”
