RSL10 Software Development Overview
Bluetooth low-power baseband is a hybrid solution consisting of hardware and software.
The baseband of the RSL10 is Bluetooth 5 certified and supports 2 Mbps RF link and custom protocol. The RSL10 Bluetooth baseband controller is connected to the RF front end. The controller will configure the physical layer of the RSL10 to be used as a Bluetooth low energy technology device. The Direct Test Mode (DTM) layer for RF testing provides interfaces and support, and implements some link layers and other controller-level components from the Bluetooth stack. The RSL10 RF front-end is based on a 2.4 GHz RF transceiver, implemented proprietary or Custom protocol Bluetooth low energy physical layer.
Application engineers mainly program through software stacks and applications. As shown in Figure 2, we can see from the link layer to GAP, the GATT layer 4 is regarded as a service with certain characteristics. Basically, the configuration file will be a series of services. The function submits the data, the latter will reformat the data, arrange the transmission, and send the data to the physical layer (or receive this data from the physical layer). GAP, GATT goes up to the configuration file to ensure low power with other Bluetooth Device interoperability. RSL10 supports Bluetooth low energy profiles such as 'Find Me', Health Thermometer, Heart Rate, Blood Pressure/Blood Glucose Monitoring, etc. For a complete list of profiles, please download the RSL10 Development Kit The application is the focus of programming, including BLE and non-BLE code. For BLE code, the application will provide or receive data to the configuration file.
Example of creating a remote keyless entry scheme using RSL10
The remote keyless entry solution refers to opening or closing the door with a mobile phone or a program key. The RSL10 Software Development Kit (SDK) provides all the relevant materials for the entire solution. Designers can build solutions and make certain evaluations based on relevant materials. The scheme is divided into central equipment and peripherals. The central equipment generally refers to the remote key transmitter, sends an interrupt to the RSL10, the application receives the command from the key, configures through the configuration file, and then the GAP, GATT is packaged and then linked. The layer is sent to the baseband controller, and the physical layer is transmitted through the radio. After receiving the command, the car parses the layer by layer in the opposite direction, and finally receives the command from the application, sends the command to the car LIN bus through I2C, and opens the door.
