How to Make an Arduino Nano Bluetooth for Airsoft

Wonder how you can pair and control your Arduino Board with Bluetooth? If so, you're in the right place! In today's Arduino Bluetooth tutorial, I'll be guiding yous on how you can easily go started!

Alongside the Arduino Bluetooth tutorial, I'll be providing:

A list of Arduino Bluetooth modules for your consideration
Arduino Bluetooth projects to go started

Footstep past Step Arduino Bluetooth Tutorial

Let's get started correct away with the Arduino Bluetooth Tutorial, where I'll provide all you need to know near pairing Arduino with Bluetooth. Ranging from hardware configurations to programming and using it with your iPhone or Andriod devices!

1. What do you need for this Arduino Bluetooth Tutorial:

You lot tin use the Arduino nano or Arduino Uno for this Bluetooth tutorial

More on the Bluetooth Module used:

Grove – Blueseeed – Dual model (HM13)

Flexible and packed with loftier Bluetooth transmission speed, the Grove – Blueseeed LE – Dual Model (HM13) uses CSR dual-mode Bluetooth chip, with the ARM architecture single flake that supports AT instructions.

This allows users like yourself to accept control over the serial baud rate, equipment name, pairing password!

You may exist wondering; why not the HC-06 or HC-05 Arduino Bluetooth module instead? Well, with the Grove – Blueseeed – Dual Model (HM13), you're getting the following primal advantages:

Bluetooth 4.0 BLE rather than Bluetooth V2.0
Depression power consumption

To not dwell on the tutorial whatsoever longer, You lot tin can notice out more virtually this Bluetooth Module here!

2. Hardware configurations:

Step 1: Connect the Grove – Blueseeed – Dual model (HM13) to a Grove port on the Grove – Base Shield via the Grove cable
Stride ii: Plug Grove – Base Shield into your Arduino lath
Step 3: Connect your Arduino to PC via USB cable

3. Understanding the software:

Conventions

In EDR mode, only the slave can be configured while either master or slave tin be in BLE mode.
Factory default setting:
- EDR Name HMSoft, Slave role, PinCode 1234
- BLE Name HMSoft, Slave role, PinCode 000000
- Baud: 115200, N, 8, ane;
AT Control format:
- Capital AT command format. string format, without whatsoever other symbol. (e.g. \r or \north).
- Whatever incorrect command would become no response.

For the total listing of AT commands, y'all can caput over to our wiki folio!

4. How to program on the Arduino Bluetooth Module

After understanding the software configurations, here'southward how to configure Bluetooth with a PC. For hardware connection, do refer to the "Hardware configurations" section. You'll notice that the flashing blue LED on the module illustrates no connection is prepare up

Step 1: Open a serial terminal and set Baud Rate: 115200, Databits: viii, Stopbits: 1, and no flow control like to a higher place
Step 2: Send "AT" to Bluetooth with the series terminal to bank check if you receive an "OK"
- The Bluetooth only respond AT commands either when:
  - No connection is set
  - All commands were seen equally cord and sent out

*You tin can distinguish the to a higher place status in stride two through LED indications.

It should look something similar this after the in a higher place steps:

Here are some useful configurations that can be sent:

Test serial connection, ship "AT", volition return "OK".
Restore manufacturing plant settings, send "AT+RENEW", return "OK+RENEW".
Reset baud charge per unit of serial port, send "AT+BAUD2", render "OK+Set:two".
Enable authentication, transport "AT+AUTH1", return "OK+Gear up:1".
Reset the Bluetooth, ship "AT+RESET", return "OK+RESET".
Query firmware version, send "AT+VERS?", return "OK+Get:HMSoftV217".
Query MAC of EDR, transport "AT+ADDE?", return "OK+Get:000E0E002074".
Query MAC of BLE, ship "AT+ADDB?", return "OK+Become:000E0B002074".
Set the name of EDR, send "AT+NAMEHM-13-EDR", return "OK+Gear up:HM-13-EDR".
Set the proper name of BLE, ship "AT+NAMEHM-13-BLE", return "OK+Set:HM-13-BLE".
Set the password of EDR, transport "AT+PINE123451", render "OK+Gear up:123451".
Set the password of BLE, send "AT+PINB123451", return "OK+Set:123451".
Enable discovery and connectable, send "AT+SCAN0", return "OK+Set:0".
Enable notify information of connection, ship "AT+NOTI1", return "OK+Set:1".
Notify information include accost, send "AT+NOTP1", return "OK+Set:i".
Enable user key, transport "AT+PIO01", return "OK+Prepare:1".
Ready to Central manner, transport "AT+ROLB1", return "AT+ROLB1".
Set to Peripheral manner, ship "AT+ROLB0", return "AT+ROLB0".

We used two Bluetooth that was connected with the PC, with ane set as central while the other as Peripheral. Several seconds later, they find each other and the LED stops flash connected!

5. How to pair Arduino Bluetooth Module with iPhone and Andriod

Since the Grove – Blueseeed – Dual model (HM13) have two protocol: Bluetooth EDR (Enhanced Data Rate) and Bluetooth Depression Energy (BLE), it can communicate with either Andriod or iPhones!

For this part of the tutorial, we'll utilize an iPhone to demonstrate how you can interact with Bluetooth!

*Annotation: The tutorial beneath is run on an older version of ios but it should even so work the same

Step 1:Power the Bluetooth and configure it as a Peripheral function

Pace 2: Search LightBlue in the App Shop and install information technology

Step iii: Launch the app, and connect to "HM-13-BLE"

Footstep 4: Touch on properties and hit "listen for notifications" to enable data receiving
- There'due south a "Hex" key on the top right under properties to modify data format too

Step 5: Striking "Write new value" and write some words to kickoff sending data to the PC

With the serial terminal, you can transfer data from the PC to iPhone too:

6. Bluetooth Data transmission guide between two Arduino boards

Now after all the in a higher place steps, are you ready to code? In this last section, nosotros'll employ two Arduino Uno and a pair of Bluetooth modules to get started!

Pace 1: Set the connexion mentioned in the hardware configurations section
Step 2: Assign the Bluetooth to Fundamental role past modifying the text to "#ascertain Main ane"
- The program of Central and Peripheral utilise the aforementioned code but there'due south a difference in the micro ascertain at the start of the program
Step three: Follow the flow chart below for initialization of the programme

After the initialization, the Central and Peripheral will practice dissimilar things; Central will send bulletin to Peripheral interval and impress what'southward received from Peripheral while the Peripheral merely responds to the central

Stride four: Download the test lawmaking and open HM-13_SW.ino with Arduino IDE, compile and download to Arduino Uno
- Recollect to configure the Bluetooth to different role by modifying the macro at the beginning
Step five: Afer program is downloaded, open 2 series final windows and wait for the Bluetooth connection
- A connection is indicated past: LEDs on the Bluetooth modules will flash for a few seconds, stop to flash, and kept on

According to the plan written, the Primal will now send a message to the Peripheral continually and get feedback every fourth dimension

List of other recommended Arduino Bluetooth modules

Now that I've gone through the above Arduino Bluetooth tutorial, here'southward a list of other recommended Arduino Bluetooth modules to endeavour! They are all Grove compatible!
