Bluetooth

Hello, I am trying to make a device or find out if there exists a device that can be programmed to send audio,video,pictures or text for marketing and advertising purposes. Say i wanted to utilize Bluetooth 4.0 which shouldn't be necessarily open for it to receive all this data. How do i go about this. Any help would be appreciated

Bluetooth Speakers

Hello everyone... rookie here.  I have been looking at the Bluetooth speakers instructables, but I was looking to take it another step.  I need to be able to also transmit to another speaker 30-40 feet away from the "master".  What would be the best way to approach this? Thanks, Tony

Is there a way to connect a bluetooth adapter to a bluetooth headset?

Usually, when you have a portable bluetooth adapter (containing a battery) you must turn it on & pair it with a smart device such as a phone or PC. Unfortunately, if your music output device is "dumb" such as a traditional MP3 player or even a turntable, there is no apparent method to get this device to pair with, say, a set of Bluetooth speakers or headphones. This is because neither of them have a display to enter a pairing code or to select which device to pair with. I'm assuming it's impossible to get two of these devices to communicate, but if anybody's figured anything out such as a wireless audio transmitter that uses traditional RF instead of Bluetooth, let me know! Thanks.

Momentary switch to Bluetooth

I'd like to make a number of smallish (say 0.75x1x2 inches) battery-powered Bluetooth boxes each of which connects to a momentary switch, and sends an RFCOMM or HID signal via Bluetooth on depression and another on release, and which will to communicate with an Android device. Because I want to make several of these, I want something super cheap and super simple to make.  (The purpose is to make a simple wireless touch detection system for foil and epee fencing. Without on-target detection, it's not going to be great, but it will be an improvement over refereeing fully dry bouts, since at least one will have proper impact and lockout timing.) Here are options I've been thinking about: 1. One thing that would *almost* do the job is to buy one of those $3-5 ebay Bluetooth phone camera remotes, and just wire my switch to it. The only problem is that according to the ads I've seen, these Bluetooth phone camera remotes go to sleep in 2-10 minutes when paired (exact timing seems to depend on the model), and I would really rather avoid this (the 10 minutes is almost acceptable). If anybody knows of a way of keeping them paired and awake for a longer period of time (say, 15 minutes or permanently), I would love to hear. This would be the cheapest and simplest solution, and it comes with a case and battery (some units are even USB chargeable).  2. On the other extreme of the price range, I happen to have some extra Brainlink modules with an atxmega and an RN-42 module inside, and it wouldn't take long to customize the firmware to do the job. But the modules sell for $39 (though sometimes on sale for $20), and that seems overkill for something so simple. And they are a touch larger than I like (about 3 inches diameter, and an awkward shape). 3. Another option might be to use a cheap serial Bluetooth module without additional hardware, and wire the switch directly to CTS. Unfortunately, I don't think the cheap HC-06 modules support CTS, though I think the HC-07 does support it (but I don't know if I can access it as it's probably not one of the pins on the header). Moreover, there are two unanswered questions on Stackexchange on how to access CTS/RTS status from Android, so this might require using a laptop as the base station (which isn't ideal). 4. A very cheap microcontroller with a UART (or just bit-banging) plus a cheap Bluetooth module. This increases the complexity of the project, but might be the way to go. More specific recommendations are welcome, as I have no experience with the hardware side of dealing with a microcontroller (on the software side, I've spent a fair amount of time tweaking the firmware of the Brainlink unit).

Bluetooth communication questions.

Hi all, I havent played with bluetooth before, so I wanted to ask a few questions before getting myself started. I want to create a simple robot that is controlled by bluetooth and make most of it from scratch. where there will be a transmitter and a receiver, followed by arduino that creates my PWM, the H-bridge and finally the motors.  I was wondering how exactly does the bluetooth work. I checked a little bit online for the prices.  the standard bluetooth dongle that connects to a PC are about 2-5$. but the arduino shields are 60-100$. I was wondering if I can get myself 2 bluetooth USB dongle and make them communicate between each other.  Is it because there are other 'modules' neccessary to properly communicate that the computer has so we cant use a dongle on the arduino which making us buy the expensive shield? So to recapitulate, my point is, can I use a standard cheap usb dongle to both send and receive information?

Bluetooth speaker not turning on?

Hi, i made a basic DIY Bluetooth speaker with a glass box. I used one 18650battery from old laptop, a charging module with protection circuit inbuilt,one stepup module to step up 4v to 5v and a 3w amplifier. It's a basic project, but the thing is WHEN I TURN THE SWITCH ON(AMPLIFIER POTENTIOMETER IS OFF) I SEE LED BLINKING ON BLUETOOTH MODULE, MEANS IT'S WORKING ,THE CIRCUIT IS OK. THE MOMENT WHEN I TURN ON THE POTENTIOMETER ON OF THE AMPLIFIER THE SPEAKER JUST SOUNDS LIKE "TICK" AND BOOM EVERYTHING SHUTS OFF. I TRIED TO MEASURE THE VOLTAGE COMING FROM STEPUP MODULE SAYS "0"V. SO I PLUGGED A CHARGER ON CHARGING MODULE AND THEN TRIED TO TURN ON AND FIRST 2 SEC SPEAKER MAKES SOME SOUND AND IT TURNS ON AND PLAYED SOME MUSIC, IT WORKED GREAT. THE THING IS WHENEVER I'M TURNING ON THE AMPLIFIER VIA POTENTIOMETER OR THE POTENTIOMETER IS ON AND I SWITCH ON THE POWER FROM THE FIRST SWITCH THE POWER CUTS. SO WHAT'S WRONG WITH THE SPEAKER. PLEASE TELL ME :(

creating a bluetooth dongle...?

ive been waiting for my dongle i ordered from dealextreme.com for far to long and i am a very impatient man. ive set out to make a dongle, or try until it finally gets here. ive considered many options but its looking like this will be the most promising. my friend gave me a slightly damaged ipod touch (2nd gen?), which i found out has a broadcom bluetooth chip in it. i ripped up the ipod, found the chip, and the datasheet. ive messed with some circuitry before, but i am lost on this. im actually pretty novice with this sort of thing, but ive experimented and learned a lot on my own. i am eager to learn. my goal is to make this into a usb bluetooth adapter. i have all the ipod parts (may need some?), usb cables are abundant, and i have a soldering gun and i am able to use it. could someone please help guide me in the right direction? i am sorry if this doesnt belong here.. this is my first post here, but ive been enjoying the site for a while now. i am a big do it yourself kind of guy and will most definitely be uploading some of my ideas when i get around to it.

[Arduino] Problem connection Bluetooth

Hi all, A while ago I got a HC06 bluetooth module. In the beginning everything worked OK, but now some problems have appeared. Pairing in Android works fine, as well as with my laptop. The problem arises when connecting my phone (Google Android 4.2 with Bluetooth 2.0 + EDR) to the device.

Arduino to arduino via bluetooth?

I want to link three arduino's via bluetooth.  One will listen for the other two.  If it receives signal it will set a pin high.  If it doesn't it will set the pin low. Two of the arduino's will be powered off most of the time.  If they power up I need it to link to the other one. So the two will need to power up, link to the one, and start sending signal. The one is just going to power up a light and maybe later also report to the web. The two are just signal generators to let the one know to turn the light on. If I can't link three, I will buy 4 and just make two pairs. Thanks for any answers.

Bluetooth vs Radio Frequency Answered

This is a 3 part question: 1. I am a bit confused. Radio frequency covers 3KHz to 300GHz, so it basically includes bluetooth(2.4 GHz). Why is it that some people talk about bluetooth as something not relating to RF. Do they have different transmission methods? WIFI is also @ 2.4GHZ. What is the distinction between WIFI and bluetooth that makes them so different, covering different ranges, and being able to send different amounts of data at different speeds. I always thought it was the frequency of the wave but WIFI and bluetooth are the same yet they are so different.  2. I am building a project. I need to send data wirelessly. The data is very simple just to turn on or off a series of leds. A friend of mine told me to use radio waves. What does he mean by that exactly since radio range is huge. Is he talking about 40MHz like the RC cars? 3.Bluetooth or RF(again im assuming this to be the same one as RC cars since i will break apart an RC car to remove the transmitter/receiver)Which method consumes less power to send the same amount of data. Distance will not be over 10 meters so i'm not worried about that.  Thanks for the help everyone, much appreciated! Chris

Measuring a Bluetooth modules output? Answered

There is a serial Bluetooth module that I have used before on an Arduino project but now I'm trying to use in a project without the Arduino. Basically I need it to be an electronic trigger, I don't care really what the signal is just how long and the voltage and current. There are 4 pins on the module: Vcc, GND, Tx, and Rx. There are 2 open pads: Key and State. When I send a command from my phone the module sends a signal out the Tx pin, and it is this signal I would like to measure so I can pick a command with an appropriate signal and tailor the rest of the circuit accordingly. I tried a voltmeter between Tx and GND but saw no signal on any level measuring DC. Is there something I'm missing? Is the signal more complex or different, or is that test setup flawed? I tried other combinations, Rx-GND, Tx-Rx, RX-Tx, GND-Tx, GND-Rx but saw nothing.

Bluetooth (HC-06) with ATtiny85

Hi everyone,      I've been playing around with the HC-06 Bluetooth module for a while now and have had great success with it so far.  However, I have been using the Arduino Uno and Pro Mini, which have quite a few unused pins in my applications.  In order to downsize I'm trying to use the Atmel ATtiny85 chip.  I have used it many times in the past so I'm at least a bit familiar with its functions and limits.  For some reason I cannot get the Bluetooth module to work with the ATtiny85.  After many long and frustrating hours spent in vain, I decided to ask you all for help.  Does anyone know of any good tutorials or code for using the ATtiny85 with the HC-06 module?  It would be great if I could use the app Ardudroid to control the ATtiny85, but any help would be greatly appreciated.   Thanks ~Dudes

Aduino Bluetooth code problem!

I am building a Morse Code machine with bluetooth functuonality.  It is in the early stages at the moment but I have hit a problem. My code uses a button to input Morse code which is displayed on an LCD and flashes an LED on pin 5, but also incorporates a bluetooth HC05 which controls an LED on pin 13. Seperately, they work fine but I wanted to merge the two sketches. I have succeeded but for one small problem. When pressing the LED 'ON' button on my android app, the LED only comes on after the Morse code button has been pressed. And it works the same way for the LED 'OFF' function on the app. Press it, then press the Morse code button and the LED switches off again. This repeats. I cannot figure out why this button is controlling the Bluetooth LED command signal. I have changed baud rates of the bluetooth but to no joy. I have attached my code. Can anyone help me solve this problem?!?

How to make a real Bluetooth range extender?

I want a bluetooth device that connects to my phone as a standard bluetooth headset and allows any bluetooth headset to connect to it as if it were my phone. I am thinking of using it (or chaining a few of them) to create a larger area for my bluetooth headset for my phone. THANKS!? (Yes...I have seen the antenna hacks, but they don't allow me to boost the power of the signal like I need to.  And, this device should also allow chaining to get the signal out a lot further and around metal obstacles.) Even better would be the ability to connect multiple devices to the extender so that multiple people could be on the same call on their bluetooth headsets simultaneously.  (Yeah...it's getting deep in here.  But the geek in me wants what it wants.)
