How Does Bluetooth Work In A Motorcycle Helmet?

When talking about how Bluetooth works, it’s important to understand what a device actually is and how it goes about sending data between two or more devices.

Audio compression is the first thing that needs to be established. This is the process of reducing the size of a file without degrading its quality. This means that Bluetooth devices must have an input, where they receive data from another source, and an output to send that data out again. The only exception would be if you are making a call or listening to music with it – then your phone does all of the work. “Calls are made using an iPhone’s built-in speaker and microphone or by using wireless Bluetooth headsets.”

Pairing is the process that Bluetooth devices go through to communicate with each other. This is when multiple devices connect with each other, like your helmet and smartphone, but only allows them to send data back and forth between each other. This limits the data being shared so that it will not interfere with any other Bluetooth devices within a specific area, usually a room or building. This is why you can leave your phone on and paired to multiple headsets at once.

Bluetooth uses four frequencies instead of just one to communicate between devices: 2402-2480 MHz, 5.15-5.35 GHz, 2.4-2.8 GHz, and the ISM band – exclusive to Bluetooth devices that are most commonly found in wireless headsets or earphones. This is why there are multiple headsets you can purchase that pair with your phone at the same time instead of having to deal with all of them pairing to your one device.

“Bluetooth is different from other wireless signals because it uses the same frequency as WiFi.” Other wireless signals use their own separate frequencies, like AM radio, radio waves, and microwaves. This makes Bluetooth very reliable when used with other electronic devices like computers or wireless game systems. This article is talking about how to use two different devices together through Bluetooth, and also explains in detail how this technology works.

 

Bluetooth is a wireless technology that connects two or more devices

It connects different devices over short distances. It uses the same frequency range as walkie-talkies and cell phones, using 4 different frequencies to transmit data at 1 Mbit/s on top of each other so there is virtually no interference.

A Bluetooth helmet can have any number of “slave” devices connected to it. These slave devices are typically headsets that allow the user to make phone calls, however they can be any number of different types of equipment.

The master device is what initiates a connection with the slave devices and controls the data transfer between these devices. This is typically mounted on or near your bike, for example in a handlebar or saddlebag.

A helmet with Bluetooth slave devices will typically have one master device. The master device manages which slave is currently being used, and tells the slave what data it needs to send or receive. To manage this, the master device creates virtual serial ports, one for each slave device. This virtual serial port is what the slave uses to send and receive information.

The Pairing Process

It begins when you turn on your Bluetooth helmet, and it asks to pair with a master device .The master device typically has a list of all slave devices that can be paired with it.

  • When you first turn on your Bluetooth helmet, you will be asked to link the master device with one of the available slaves (you may also need to enter a passcode).
  • Once connected, each slave device has a unique ID that the master uses to refer to it. The master will select one slave from its list and tell it what kind of data it needs from it. An example would be for a phone call – the master tells the slave “incoming call, play this ring master device to that slave.
  • When the master is linked to one slave, it will remember it and not accept pairing requests from other devices. This prevents multiple headsets connected at once.
  • The pairing process is completed, and now the slave has been connected to the master device.
  • The master device manages which slave is currently being used, and tells the slave what data it needs to send or receive. To manage this, the master device creates virtual serial ports, one for each slave device.
  • Each virtual serial port is what the slave uses to send and receive information.

 

A motorcycle helmet has speakers and microphones on the inside, which use Bluetooth to connect with your phone

Many Bluetooth helmets also have the ability to pair with two different phones at once, allowing for easy communication between both of them. This allows you to answer calls from either one, or have a conversation on the phone using both devices at the same time.

The speaker and microphone components on your helmet use the same four frequencies that Bluetooth devices use to transmit data over short distances, making them ideal for an in-helmet design. This means that any other Bluetooth device can connect with your helmet at any time.

 

The microphone in the helmet picks up sound from your voice, while the speaker plays back what you are hearing

This allows you to have a conversation, or listen to music while riding.

One of the most common uses for Bluetooth is with a phone, which allows you communication with other people over long distances. The headset in your helmet can connect to your phone and allow you to make calls without ever needing to remove it from the motorcycle. Instead of taking off your gloves and exposing your bare skin to the cold weather, you can stay warm while still being able to answer a call.

It is possible for Bluetooth devices to connect with each other at the same time through what is known as pairing.

An example would be if both a headset and a phone were paired with a motorbike helmet – the headset would connect with the helmet and the phone would connect with the helmet. This allows you to answer calls from either one, or have a conversation on the phone using both devices at the same time.

What differentiates them is how they transmit data back and forth between each other. Every Bluetooth device that has an address needs to be paired with one another to communicate with each other.

When the master is linked to one slave, it will remember it and not accept pairing requests from other devices. This prevents multiple headsets connected at once.

Pairing two Bluetooth devices together does not prevent them from being paired with any other devices, which allows for multiple phones or headsets to be connected to the same helmet.

When using an intercom, each slave has its own unique ID that the master uses to refer to it. The master will select one slave from its list and tell it what kind of data it needs from it. An example would be for a phone call – the master tells the slave “incoming call, play this ring tone on this slave device”.

Each serial port has a pair of virtual ports created for it. One is for sending data, and the other is for receiving data. This allows multiple devices to communicate with each other at once through different virtual serial ports using an intercom.

The speaker and microphone components on your helmet use the same four frequencies that Bluetooth devices use to transmit data over short distances, making them ideal for an in-helmet design. This means that any other Bluetooth device can connect with your helmet at any time.

Communication is handled through one master and multiple slaves, allowing the user to control the setup. This means that you’re not limited to just a phone and headset, as you can connect as many devices as you want to your helmet and control them all from the center console on your handlebars.

 

Reminders when using Bluetooth Helmets

Always remember to turn off or disconnect it when not in use so as not to drain battery power

Disconnecting the device also prevents them from draining power while not in use. This will prevent the headset’s battery from running down faster than normal, allowing you to ride longer on a single charge.

To disconnect, press and hold down the power button on the headset for six seconds. This will tell the headset to shut down, disconnecting it from any other Bluetooth devices that are connected to it.

Even when only paired with a phone, your device should be disconnected when you are not using either of them to prevent battery drain. If it is left on all the time, your battery life will be much shorter.

When you are using an iPhone, there is no need for external speakers because it has its own built-in ones located at the bottom of the device 

This will allow you to hear everything while riding without having to use an extra Bluetooth headset or speakerphone.

If your phone does not have speakers built inside, using a set of Bluetooth headphones is recommended. These earphones are only two inches long and sit just below your ears in the hollow of your throat. They can then be wired into the phone for sound.

Some Bluetooth devices, like the Sena SMH5, allow you to pair multiple headsets at once. This will mean that two or more people can listen to music or take phone calls at the same time. Just remember that there needs to be one person controlling the center console on their handlebars since it does not connect with multiple devices at the same time. 

Some headsets can be connected to multiple headsets for added entertainment, but only one person should control the center console at once capable of connecting to multiple devices at once.
