DFRobot Bluetooth V3 not detected...
MrAlexis44600 2011-08-24 08:05:41 7227 Views7 Replies Hello,
I purchased a DFRobot Bluetooth V3, and after supplying it with power, I still can't detect it with any of my bluetooth devices: My android cell phone, my laptop and my computer using an USB bluetooth adaptor. Is not the DFRobot Bluetooth V3 supposed to be ready to use? The "STATE" button blinks very slowly.
If someone could help me, I search for a troubleshooting page but couldn't find anything.

2012-02-07 23:00:07 to change the baud rate, please refer [url=https://www.dfrobot.com/image/data/TEL0026/TEL0026_Datasheet.pdf]https://www.dfrobot.com/image/data/TEL0026/TEL0026_Datasheet.pdf[/url] for more detail. Just some AT command, quite simply to execute

Sorry for the delay. We moved to a brand new office this week :D
Here is a connection diagram for the bluetooth module.

Hector 2011-08-30 07:43:52 Hi, some news:
I have successfully connected my Bluetooth V3 with my computer ( as serial connection COM7), but my android is still not seeing it.
I tried to communicate with the help of my duelaminove (using RX and TX pins and the serial monitor of the arduino IDE) but without any answer to the message "AT"
Maybe I made a mistake somewhere....How must I wire it? I tried both:
RX => RXD and TX to TXD or TX =>RXD and RX => TXD ? MrAlexis44600

You can use it with the Duemilanove. You can not use it with an Arduino UNO. Hector

Hector 2011-08-25 10:55:00 Hi hector, thank you for your help.
It seems that mine blinks faster than the video's one when AT mode is off, and faster when AT is on.
I still can't detect it with any of my devices.
I will try to comunicate with it using the Red Back Spider Controler (arduino mega based board), because I can't use my duelaminove if I understood well. MrAlexis44600

Please take a look at the following video: http://www.youtube.com/watch?v=rT31q1vdhAg
tell me if the blinking is similar. Also, at arround 45Secs. the video shows the connection process.
