                                                                                                  2611011024010 is a Proteus-III-SPI Bluetooth® LE 5.1 module (radio sub-module/device) for wireless communication between devices such as control systems, remote controls, sensors et cetera. On the basis of Bluetooth® LE 5.1. it offers a fast and secure data transmission of data packages between two or more parties (point to point topology). A SPI is available for communication with the host system. The Proteus-III-SPI uses the Bluetooth® LE standard to provide general data transmission between several devices. The standard itself offers a wide range of configurations and possibilities to suit and optimize sophisticated customer applications. To fulfil the needs and specifications of such applications a tailored firmware can be developed on the basis of the Proteus-III-SPI hardware. This includes the connection and communication to custom sensors, custom Bluetooth® LE profiles, timing configurations, security configuration as well as power consumption optimizations.
