This page describes the Progressor\u2019s Bluetooth interface and is intended for users who want to develop a custom application for their device. The description assumes a basic understanding of the Bluetooth LE protocol.<\/p>

\u00a0<\/p>

The Progressor, with its Bluetooth 5 connectivity, can connect with most modern PCs or smartphones. Once a connection is established, the client application can control the Progressor\u2019s operation through the commands specified here.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Bluetooth Services<\/h2>

The Progressor includes two Bluetooth services, one custom \u201cProgressor\u201d\u00a0service which exposes the Progressors control interface, and the second one is\u00a0the Nordic device firmware update (DFU) service. The DFU service will, however, not be covered\u00a0here as it only accepts updates signed by Tindeq.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Control Point<\/h2>

The control point characteristic is where we send commands to the Progressor. Each command is encoded into a tag-length-value (TLV) type of format<\/span> as shown in Figure 2.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Data Point<\/h2>

The data point characteristic is where we receive data from the Progressor. The data is encoded into the same type of TLV format used for sending commands. Note: to receive data, the client must enable notifications for this characteristic first.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Test tools<\/h2>

nRF Connect<\/a> for mobile is a generic Bluetooth developer app available for both Android and iOS. It is a convenient tool for inspecting and interacting with services and characteristics on Bluetooth LE enabled devices and can also be used for test and verification of the Progressor.<\/p>
