How to Configure

Configuring Bluetooth modules involves setting them up for use. The processes include:
> Construct a primary circuit by connecting the Arduino pins to the Bluetooth module’s voltage pins.
> When you’re making use of a completed drop controller to configure the Bluetooth module, turn the Bluetooth module on after downloading the serial pass with the aid of an Arduino sketch.
> Make sure the LEDs of the Bluetooth module are blinking (that’s how you’d know it’s turned on).
> Attempt using your Android mobile phone to connect with the now turned-on module. (Connection can only be achieved with an Android device).
> Turn on your android device’s Bluetooth and scan for the name, MK15.
> Click on the name and pair with the module as you would in a usual Bluetooth connection.
> A four-digit pin may or may not be required. If one is required it is usually simple combinations like ‘1234’ or ‘0000’. Though it is usually stated in the product’s package.
> Being able to successfully pair with the module tells you it is in working and communicable.
> You then communicate with the module through the Arduino sketch serial pass.
> At a specific speed of less than 10000 bp, a short coding of the sketch induces the hardware and software serial to open to await imputation of the serial data.
> The transfer of imputed information can either be from the Bluetooth module to the Hardware serial or Vice-versa. Depending upon where the data were imputed.
> After opening the serial monitor of the downloaded Arduino sketch, change the baud rate to the same speed as above.
> Set ‘no line ending’ as your preferred line endings.
> Wait a few seconds for the welcome message.
> Check and confirm that the Module’s LED light is blinking.
> On the opened serial monitor type ‘AT’ tap on send.
> After getting ‘OK’ in reply. (Troubleshoot your connections if you do not)
> Change the name of the Bluetooth module by entering and sending the command ‘AT+NAMEname’ on the serial monitor. (The lower case name represents your name of choice).
> Getting the reply ‘OKsetname’ confirms that the rename was successful.
> You can then wait a minute and repeat the Bluetooth search process with your android. The name should be changed.

How to use

Bluetooth modules are generally easy to use. Here are answers to a few FAQs for a better user experience.

How do I customize my Bluetooth module’s parameters?
After configuration, you can adjust all the parameters on the module from the AT command mode. To get into the AT command mode. Simply pull the pin that reads Button switch.

Why can’t I adjust my Module’s Parameters?
You need to unpair all the Bluetooth devices paired with the Bluetooth module in order for the AT command mode to be accessible.

How’d I know if my Bluetooth Module is paired?
The blinking speed of the LED lights tells you if any device is paired with your Bluetooth module or not.
Series of fast-paced blinks indicates that your module’s signal is not being communicated or transmitted with any Bluetooth device. Meaning your module is not paired with any device.
Slower LED blinks seeing about a blink every 3 seconds on average. Indicates your Bluetooth module is currently paired.

How can I take better care of my Bluetooth module?

The most effective way to do this is by being intentional about learning all the components of the module. And what they are responsible for. This would reduce the chance of you causing any damage to the module or any hazard to yourself as a result of ignorance.
