The HID specification is a part of the USB standard, thus USB mice and other USB user input devices are HID compliant.<\/p>\n\n\n\n<p>The&nbsp;<em>host<\/em>&nbsp;and the&nbsp;<em>device<\/em>&nbsp;are two entities in the HID protocol. The device is the entity that directly interacts with humans, such as a keyboard, mouse and BleuIO. The host communicates with the device and receives input data from the device in messages with 64 bytes size.<\/p>\n\n\n\n<p>HID devices must meet a few general requirements that are imposed to keep the HID interface standardized and efficient.&nbsp;<\/p>\n\n\n\n<p><strong>Demo application&nbsp;<\/strong><\/p>\n\n\n\n<p>Bluetooth Special Interest Group (SIG) defines a HID profile that specifies how a device can support HID services over the Bluetooth LE protocol stack using the Generic Attribute Profile.<\/p>\n\n\n\n<p>This example implementation shows how BleuIO can be used with the USB HID profile. The application allows to send BleuIO AT commands and displays the response on the screen.&nbsp;&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"638\" height=\"738\" src=\"https:\/\/www.bleuio.com\/blog\/wp-content\/uploads\/2022\/01\/Animation.gif\" alt=\"\" class=\"wp-image-145\"\/><\/figure>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The BleuIO is a Bluetooth low energy USB dongle that can create new BLE 5.0 applications in the fastest and easiest way.
