Tap Personal Hotspot.
3. Tap the Personal Hotspot switch on.
Take note of the Wi-Fi Password given on the Personal Hotspot screen.
If Bluetooth is turned off, a notification appears asking if you want to turn on Wi-Fi and Bluetooth or use Personal Hotspot only with USB.
4. Choose one of the following options to connect:
• To connect a computer using the Personal Hotspot feature’s direct cable option, connect iPhone to your computer with the USB cable. In Network Preferences, choose iPhone. Follow the onscreen instructions to configure the connection if this is the first time.
• To connect a computer or other device (such as an iPad, another iPhone, or an iPod touch) using that device’s built-in Wi-Fi feature, choose your iPhone from the list of Wi-Fi networks that appears on the device. Type the Wi-Fi password shown in the Personal Hotspot settings.
A blue band appears at the top of your iPhone screen whenever a device is connected.
Bluetooth
The iPhone uses the Bluetooth 4.0 protocol. Bluetooth is a short-range (up to 300 feet) wireless protocol used to attach, or pair, devices to your iPhone. Unlike Wi-Fi, which broadcasts its availability continuously, Bluetooth has to be turned on to make your iPhone or other device discoverable so that they can see each other. A passkey or PIN is used to make that connection private.
The most common devices paired with iPhone are a wireless, or hands-free, headset or wireless speakers. Other devices that you may want to pair with your iPhone are earphones for listening to music, a physical keyboard, or your car so you can answer calls by tapping a button on the steering wheel or radio. If you pair two iPhones, you can share photos, files, and even an Internet connection between them. To connect devices to your iPhone via Bluetooth,
1. On your iPhone, open the Settings app, tap Bluetooth, and tap the Bluetooth switch on, or just drag up from the bottom of the screen to open the Control Center and tap the Bluetooth button.
The Bluetooth screen opens, as shown in Figure 2-6. Tapping Bluetooth on makes your iPhone discoverable, which means other devices with Bluetooth turned on can see your iPhone. The Bluetooth icon appears in the Status bar.
Figure 2-6: Bluetooth lets you connect devices to your iPhone.
2. Turn on Bluetooth on the device you want to connect so it’s discoverable.
If the device is another iPhone or computer, you have to turn on Bluetooth on that iPhone or computer, too. Active devices show up in a list on the Bluetooth screen on your iPhone.
A Bluetooth headset only needs to be turned on. Obviously a headset doesn’t have a keypad to enter a passkey, but it may come with an assigned passkey, which you need to pair with your iPhone. Check the instructions that came with the headset for the passkey code or try 0000. (It’s usually the default code.)
3. In the list, tap the device you want to pair with your iPhone.
4. Enter the passkey on the keypad that appears on your iPhone, if requested.
The two devices can now communicate across the Bluetooth connection.
5. To turn Bluetooth off and make your iPhone undiscoverable, open the Settings app, tap Bluetooth, and tap the Bluetooth switch off, or just drag up from the bottom of the screen to open the Control Center and tap the Bluetooth button.
The Bluetooth button on the Control Center is dimmed and the Bluetooth icon disappears from the Status bar.
GPS
iPhone’s built-in GPS (Global Positioning System) sensor determines your location. Apps like Compass and Maps use GPS to pinpoint your location. The Camera uses GPS to do geotagging, which is adding the location to a photo when it’s taken. Reminders uses GPS to provide location-based alerts. The GPS is accessed when you check in to some third-party apps or social networks.
When you turn on Location Services in the Settings app (tap Privacy and then tap Location Services), the GPS sensor is activated. We explain the features and functions of Location Services in Book I, Chapter 4.
Printing from your iPhone
The utopian idea of a paperless society may be near, but it hasn’t arrived yet. Words and images on a piece of paper are sometimes necessary. AirPrint enables your iPhone to print directly to an AirPrint-enabled printer. Many types of files can be printed: email messages and any readable attachments, photos, web pages, even PDFs. Apps you download from the App Store may also support AirPrint. AirPrint couldn’t be easier. Here are the steps to take to print from your phone:
1. Make sure the printer you want to use is on the same Wi-Fi network that your iPhone is connected to.
2. On your iPhone, open the document you want to print.
3.
4.
The Printer Options screen opens.
5. Tap the Printer button to select the printer you want to use.
Another screen opens, showing the printers that are available in the Wi-Fi vicinity.
6. Tap the printer you want to use and then tap the Back button at the top left of the screen.
7. Select the number of copies you want to print by tapping the plus and minus buttons.
Depending on the app and the printer, you may also have the option to choose double-sided printing and/or a range of pages.
8. Tap Print and walk over to the printer to pick up your page.
Adjusting Accessibility Options for Easier Operation
With the Accessibility settings, Apple addresses the physical challenges that some users may have with iPhone’s interface. They’ve created optional features that customize the interface to make iPhone more accessible. Open the Settings app, tap General, and tap Accessibility. Many of the options have subsequent settings when tapped in the list. We recommend that you consult Chapter 32 of iPhone’s User Guide (http://manuals.info.apple.com/en_US/iphone_user_guide.pdf or in the iBooks Store for free) for complete instructions on how to get the most out of the Accessibility features. The features are divided into five categories: Vision, Hearing, Media, Learning, and Interaction. Here we briefly explain each feature:
✔ VoiceOver: Turn this setting on to hear an audible description of the buttons on the screen. With some practice, vision-impaired iPhone users can learn the tapping, double-tapping, and flicking movements necessary to use apps. Within VoiceOver, you can adjust the speaking rate, attach a Braille device, select which parts of a web screen you want to have read to you, and which language you want VoiceOver to speak.
✔ Zoom: The Zoom feature enlarges the entire iPhone screen when you double-tap with three fingers. Use three fingers to move from left to right on the screen and one finger to move the screen up and down. Double-tap again with three fingers to return to normal size.
