A client has to configure Indications and Notifications for a characteristic\u2019s value through its client characteristic configuration descriptor to get notified every time a characteristic\u2019s value gets updated on the server.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Indications<\/strong>&nbsp;need to be acknowledged by the client. The server does not send the following indication until it gets the acknowledgement back from the client. The client sent a confirmation message back to the server; this way server knows that message reached the client. Hence communication via indications is slower.<\/li><li><strong>Notifications<\/strong>&nbsp;don\u2019t need to be acknowledged, so they are faster. Hence, the server does not know if the message reaches the client.<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/smartsensordevices.com\/wp-content\/uploads\/2021\/10\/indication_confirmation_ble.png\" alt=\"\" class=\"wp-image-1301\"\/><\/figure>\n\n\n\n<p>Indications and Notifications are essential mechanisms for receiving server-side data because they are the&nbsp;<em>only<\/em>&nbsp;and fastest mechanisms for receiving asynchronous server-side updates. Since Bluetooth Low Energy was designed to be energy efficient, this asynchronous method of receiving updates prevents continuous polling of the server by the client and, hence, is a huge energy saver too.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>BleuIO released a new firmware version 2.0.8 on October 22, 2021, introducing new features and enhancements to improve productivity.
