for rx and tx you don't need to bypass anything as far as i can tell. as Mellis said, digital pin 0 and 1 are marked rx and tx. all data you send through the serial interface does flow through your usb-port to your computer and at the same time through the tx-pin. incoming data is read both from the usb port (coming from your computer) or the rx-pin on arduino.
this should be true as long as you don't assign any other function (digital in or out) to those pins.
(SPECUALTION AHEAD!)
as for RTS and CTS (ready-to-send/clear-to send) on your bluetooth module you can just connect them to each other i guess. those lines are used for flow control, i.e. to signalize that a device is ready to send or receive data. if you experience problems you might bypass/grab those line from somewhere on the board. maybe someone more familiar with the board will help you then.
Well the components are on their way being shipped. so when they get here i can start playing immediatley and will post my progress - probably in a new thread or something..
Thanks for your info regarding this matter - you know quite a bit and it willl be helpful to know!
Regarding the RTS and CTS - if anyone knows wherher i have to bypass/grab those lines from somewhere on the board, please let me know!
Hi! mitcho , I had already add a bluetooth modem to Arduino last month , and it works very well , you can see the pic :
I don't know your bluetooth modem works at 3.3v or 5v , my modem is work at 3.3v ,so I need to turn 5v to 3.3 . the leaved things is just connect the pin0(Rx) of Arduino to the TX of your modem , pin1(Tx) of Arduino to the RX of your modem , than connect the BT to your PC or PDA , you can get the date from Arduino and can send date to it just like there is a series cable , and you can use Arduino IDE to download program to the board via BT modem .
that is excellent you got working!! - for me i could not use the same modem u used. u use a very BIG modem - i need something small that can be 'wearable' (like the one i ordered Bluetooth Modem - BlueSMiRF RP-SMA - WRL-00158 - SparkFun Electronics) < i will use this one when it arrives!
but i am very happy that yours works. this means that it can be done successfully! CONGRATULATIONS!
can i have your email address, so i can contact you about setup details.
Oh ok - i see now. the modem is the small chip. did you have to attach to big board to get the power to 3v, or is it because you use the big board for other thing.
i can use 5v to power modem i ordered so i will just attach it straight onot arduino.
The big board used to control the motor of my robot , you are so luckly ;), you can use 5v to power modem , it make things very easy , if I live at USA , I will buy one modem like yous , but I in China , the postage is very costly
It's a net control robot , you can control it , see it , receive the date from it in the browser(with flash player)
but the server is just my PC , so I can't open it all the day.
and I make a video of it , you can see at : http://www.eiart.net/robot/ but it is big (30M, 20min)
If you want to try , you can leave a time(the time here is UTC+8)as a reply here(english) : http://eiart.net/blog/archive/218
then at that time we arranged , if I open my server , you can try to control my robot.
