Bluetooth (together with low power wireless technologies such as Zigbee) are significant technologies that make &#8220;The Internet of Things&#8221; possible. These low power wireless technologies enable all kinds of devices to communicate with each other and with other devices such as Android phones and tablets.<\/p>\n<p>Today, most Bluetooth devices run Bluetooth version 2.1 up through version 4.2, depending on the device. Bluetooth has undergone considerable enhancements and evolution over the years from providing a short range, lower speed serial data link suited for wireless earphones to providing high speed packet data communications over short distances while using very low power.<\/p>\n<p>Bluetooth continues to evolve with Bluetooth version 5.<\/p>\n<p>Bluetooth 5 adds more improvements including:<\/p>\n<ul>\n<li>Up to 4x longer range<\/li>\n<li>Faster data rates &#8211; on par with WiFi for some applications<\/li>\n<li>Lower power<\/li>\n<\/ul>\n<p>However &#8211; and this is important, most Bluetooth version upgrades require new hardware, and this is true for Bluetooth 5. To use version 5 features you will need version 5 compatible hardware &#8211; which is not yet generally available on Android phones and tablets.<\/p>\n<p><!--more--><\/p>\n<p>Because of this, it will be a while before new Bluetooth features are widely available on many devices.<\/p>\n<p>Some phones, like my Nexus 5, support many &#8211; but not all features &#8211; of Bluetooth LE (a version 4.x enhancement). To get version 5, I will need to eventually buy a new phone.<\/p>\n<p>Many Bluetooth modules sold for use with Arduino boards are compatible only with version 2.1 of the Bluetooth specification. In theory, newer devices will be backwards compatible &#8211; that is, a version 4 device should be able to talk to a version 2.1 device, but only using version 2.1 features and capabilities.<\/p>\n<hr \/>\n<p><em>Why I am putting hashtags like #Bluetooth in the title of the blog posts?<\/em><\/p>\n<p>Hashtags assist in searching for information on Twitter, Instagram, Tumblr, Facebook and other social media outlets.<\/p>\n<p>This blog transfers posts to Twitter and Facebook pages using a software module that uses the title and adds a link to the blog post. To add #hashtags to those social media posts, I need to put the #hashtags into the blog post title. Until a month ago, I used a different software module that permitted me to add the #hashtags only to the posts going to social media. Unfortunately, that software module&#8217;s support was turned off and is no longer usable &#8211; I had to switch to a new solution which did not have that feature.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Yesterday I posted another item in a series of posts about using Bluetooth features in App Inventor.
