The SimpleLink™ SDK Bluetooth Plugin is a companion software package that enables the use of a Bluetooth Network Processor (NWP) on a Host SimpleLink platform. This software package supports the MSP432P4, MSP432E4, and CC32xx devices as Host platforms, and the CC2650MODA, CC2640, and CC26x2R1 as Bluetooth Low Energy Network Processors. By using a supported Host platform along with a supported Network Processor, this two-chip solution can act as either a GAP Peripheral role or a GAP Central role. This software package works in tandem with a SimpleLink software development kit (SDK) to provide a portable and expandable Bluetooth programming suite. Through the ability to seamlessly and modularly add Bluetooth functionality (more specifically Bluetooth Low Energy/BLE) to an embedded system, a programmer can enable their embedded device to become a gateway to various IOT infrastructures.
For examples demonstrating the two-chip solution in a peripheral role, the plugin leverages the use of the TI Simple Application Processor (SAP) driver connected to a CC26xx Simple Network Processor (SNP) to provide a highly customizable hardware configuration. For software connectivity between the SAP and the SNP, an architecture agnostic HAL/Drivers layer is used to promote software portability and maximize collateral reuse.
For examples demonstrating the two-chip solution in a central role, communication between the NWP and the Host occurs through a UART serial interface using the Host Controller Interface (HCI) protocol. TI Vendor Specific HCI commands and a limited subset of Bluetooth LE HCI commands/events are supported to implement a Bluetooth application. By using TI Vendor Specific commands and events, the application can communicate with and access the BLE stack.
