Upload Sketch Arduino over Bluetooth using Android.You could get an excellent Bluetooth keyboard controller from Adafruit called Bluefruit EZ-Key which allowed super easy creation of projects that sent keyboard presses for example a gamepad just by connecting some switches to the pins. After an evening of trying, I decided to give up on that.

Throw me a comment if you have that working! This package ought to contain:. Sounds a too good deal to be true? The keyboard has a solid metal backplate that is easily screwed open with micro cross head screwdriver.

Taking the tape off and turning the board around reveals a bit spacious, but very professional looking PCB with clear markings. Time to dig out my trusty Picotech scope and do some old-fashioned reverse engineering! I connected the board to USB power so I would have GND levels aligned, that way I could ditch the ground connection from the probe and use just the sharp tip.

The battery was in good shape giving out around 4 volts. The board is most likely a 3. Turning around the PCB gives a nice access to the connector pins using my probe:. I initially thought there was maybe some transmission protocol coming from the keyboard, but then in occurred to me that this would most likely be too complicated.

If you would like to wire for example six buttons to a microcontroller, you usually would set six pins as inputs with a pullup resistor, then wire each pin to a button that is connected to ground on the other end.

Now take a look again at the connector panel:. Here is for example C1 being set to GND:.

Row pins R0-R7 are by default high, but once I pressed arrow right wired between R0 and C1 as this example will show on the bluetooth keyboard, you can see R0 going down.

After some initial changes most likely there is some interrupt routine conserving power when no keys are pressed the pattern will match the pattern output to C1 pin — as no other keys are held down, the R0 is basically connected to C1. Now that we know the logic, the procedure is simple:. You can do step one with an oscilloscope, multimeter or even just LED and resistor in series. By the way: the charging LED was annoyingly bright so I used a black marker on that one in order not to go blind while debugging!

Word of caution: Be very careful not to short two Cx pins, as the MCU is driving voltage in them, you may damage or even cripple your relatively cheap board that way!The Bluno Beetle Bluetooth 4.

It is one of the most popular and most frequently used low range communication for data transfer, audio systems, handsfree, computer peripherals etc.

But in all those projects, I have not discussed a lot about the Bluetooth Module, except for what is required to get the project done.

If you take a look around the electronics DIY and hobbyists community, HC Bluetooth Module is the device of choice for implementing Bluetooth Communication based projects. Such Modules come as surface mount board and several third-party manufacturers use these board to build a more complete system with necessary pins and components. The following image shows one such HC Bluetooth Sub Module the green board mounted on the blue board being used as a part of a complete Bluetooth Module.

In my case, the board uses the UART communication. Image below shows the pins and other components on a typical HC Bluetooth Module.

An important point to remember is the HC Bluetooth Module works on a logic level of 3. Hence, a 3. This part of the Module is not discussed in this project. When the module is not paired, the LED blinks or flashes repeatedly. Once the module is paired, the LED blinks at a constant delay of 2 seconds. In Command Mode, you can communicate with the Bluetooth module through AT Commands for configuring various settings and parameters of the Module like get the firmware information, change UART Baud Rate, change module name, set it as either Master or slave etc.

An important point about HC Module is that it can be configured as Master or Slave in a communication pair. In order to select either of the modes, you need to activate the Command Mode and sent appropriate AT Commands. Coming to the Data Mode, in this mode, the module is used for communicating with other Bluetooth device i. The following is a list of few of the default settings of the HC Bluetooth Module.

The aim of this circuit is to connect the Bluetooth Module with Arduino, Pair the Bluetooth Module with an Android Phone, send data from Android Phone to the Bluetooth Module using a simple App, read the data from Bluetooth Module through Arduino and finally, display the data and control a device based on the data. Following image shows the circuit diagram of the connection between Arduino Mega and HC At the time of developing this project, this particular Bluetooth Controller App is no longer available in the Play Store.
