Android O feature spotlight:

Android O feature spotlight:

1. Connectivity enhancements : 
Automatically enable WiFi when you're near a saved network, There's a toggle for this feature in the O preview WiFi settings, but it's grayed out along with the open network notification. Although, it's off whereas the network notification is stuck on. Presumably this will be accessible in a future version of Android O. We've still got three more builds before the final one.


2. Picture-in-Picture mode
Picture-in-picture, which is already available on Android TV, is coming to Android O. This is mostly used for video playback. Android O won't be restricted to phones, so there will be improved arrow and tab key navigation for when used with a physical keyboard.

3. Multi-display support
Interestingly, Android O will be able to support multiple displays, allowing a user to move an activity to one screen to the next.
4. Notifications in Android O
Many of the new features regard notifications, and in Android O we will see user-customisable notification channels whereby alerts are grouped by type. Users will be able to snooze notifications, and devs can set time limits for notifications to time out. Also adjustable will be the background colours of notifications, and the messaging style.

5. Background limits
In Android Nougat Google introduced the ability to restrict certain app activities in the background, and in Android O it improves on this by placing the priority on extending battery life without user-input.

6. Better management of cached data
Every app will have a storage space quota for cached data, and when the system needs to free up disk space it will delete data from apps using more than their allocated quota first.

7. New enterprise features
Google says it has made the profile owner and device owner management modes more powerful, productive and easier to provision than ever, with highlights including the ability to use a managed profile on a corporate-owned device and enterprise management for file-based encryption.
You can read about the new updates coming to Android O in more detail over on the Android Developer's site.

8. Copy Less
This feature is expected to ease copying text from one app and pasting it within another by giving suggestions in the second app as to what you might be about to type based on what you were doing in the previous app.

9. Improved gestures
Today you can quickly call up your contacts using Ok Google, but in Android O you will be able to draw onscreen the letter C to open your contacts menu. This is similar to what we've seen in many Chinese phones - the ability to in standby mode draw onscreen a letter and open an app of your choice - though here it should work when the screen is switched on and in any app. This feature may not be ready in time for Android O, however, the source warned.

Why Bluetooth required for IOT success?



Bluetooth technology is already embedded in current day to day lives, and it will continue to have an impact to make “Things” smarter. Instrumentation can become smarter with wireless data capture. Wireless data reporting, or capturing, offers convenience and efficiency to many different industries. Spectrum and reliability of Bluetooth would be a good differentiator.

In the Education field, Teachers can quickly monitor student’s reports/status from a mobile device instead of walking from room to room and paying attention to everyone. Consumers can enjoy music from their wireless Bluetooth headphones and track their heartbeat and progress from a wearable, Bluetooth-connected device while running. House doors can be unlocked and lights can be turned on or off by simply touching your smartphone. Even industrial machines can be monitored and controlled by a Bluetooth-connected device to determine their status or predictive maintenance needs. Bluetooth beacons would be available with different options.

Bluetooth, which operates in the 2.4 GHz band using frequency hopping spread spectrum on 79 1-megahertz channels, has kept pace with technological evolution and found a place in both consumer-facing “Internet of Things” uses – smart homes and wearables, for instance – as well as in the industrial “Internet of Things” where adaptability and reliability are requisites.

Expectations for more immediate control of network-connected IoT devices through smartphone apps translates into a growing need for simultaneous connectivity to Bluetooth mobile devices and 802.15.4 networks. For example, users will expect to interact through their smartphones directly with an IoT device in an appliance even while that same device communicates with the cloud for overall home management services or if the device temporarily loses its cloud connection.



To make this point, let’s take a look at a new Bluetooth module from Silicon Labs. The Blue Gecko BGM113 module has a 3-decibel mill watt power output optimized for applications with a 150-foot range; the company says this is a good fit for “smartphone accessories, wearable sports and fitness products, wireless locks and point-of-sale devices.”




In keeping with IoT product trends in both the industrial and consumer space, unit price and battery life are huge considerations. These items are most important factors for Industrial IOT.


Bluetooth low energy also provides much lower power consumption than Classic, which is useful in battery operated systems such as wireless sensors.”
