About Connect and RAIL
The Flex SDK provides two paths to application development. The first begins with Silicon Labs RAIL (Radio Abstraction Interface Layer), which is an intuitive, versatile radio interface layer that is designed to support the implementation of arbitrary wireless protocols. The second uses Silicon Labs Connect protocol stack, which provides a fully-featured, easily-customizable wireless networking solution optimized for devices that require low power consumption and are used in a simple network topology. Connect example functionality is provided through easily-configurable components that can be turned on or off as desired.
Whether you begin development with Connect or RAIL is determined by the example application you select as a starting point in Simplicity Studio. Silicon Labs recommends that you start from a Connect example if you want to include the following functions without further development:
MAC layer functionality including frequency hopping and security Network formation and, for star networks, routing support Application-level functionality, including diagnostics, I/O, mailbox, and sleepy end device management Bootloading, including serial and Broadcast or Unicast OTA (over-the-air)
The following sections provide additional detail on Connect and RAIL, including brief descriptions of the example applications. When you create a project based on an example, the Project Details on the Simplicity Studio IDE Overview tab provides additional detail about the example and interfacing with it.
Silicon Labs Connect
Silicon Labs Connect functionality for the EFR32 is implemented on top of the RAIL library. Silicon Labs Connect supports many combinations of radio modulation, frequency and data rates. The stack includes all MAC layer functions such as scanning and joining, setting up of a point-to-point or star network, device types such as sleepy end nodes, routers or coordinators, radio configuration, frequency hopping and LBT (Listen Before Talk) protocols required for regulatory compliance in each geographical region, and PHY configuration for each of these regions. With all this functionality already implemented in the stack, developers can focus on their application development and not worry about the lower-level radio and network details.
The Flex SDK includes a number of Connect example applications including the following.
Connect SoC – Empty: A minimal Connect project structure, used as a starting point for custom applications.
Connect SoC – Direct mode Device: Demonstrates direct communication between nodes in range. The network parameters are commissioned by the application.
Connect SoC – MAC Mode Device: Demonstrates direct MAC mode communication between nodes in range.

Silicon Labs RAIL
Silicon Labs RAIL provides an intuitive, versatile radio interface layer designed to support proprietary or standards-based wireless protocols. RAIL is delivered as a library that you can link to your applications. A description of library functions is provided in the development environment. The RAIL API is documented in an online API reference available through Simplicity Studio and online at https://docs.silabs.com/.
RAIL:
Implements commonly-used radio functionality, so that it does not have to be written in the application or stack. Eliminates the need for developers to become expert in RF register details of complex wireless SoCs. Simplifies code migration to new wireless ICs and the development of new stacks by providing a common radio interface layer. Allows lab evaluation in addition to application code development.
The RAIL library supports APIs for:
General Radio Operation Channel definition and selection Output power configuration Transmit Clear Channel Assessment before Transmit Scheduled Transmit Energy Detection Receive Packet Filtering Calibration CW (Carrier Wave) Transmission Modulated Transmission RFSense configuration as wake source
The Flex SDK includes example RAIL application code to demonstrate the capabilities of the device and the RAIL library. These examples are provided as source code to offer a starting point for application development. The following examples, among others, are included in the current release.
RAIL SoC RAILtest
RAILtest is a general test tool for the RAIL library. RAILtest is developed by the core engineering team working on the RAIL library. As each RAIL library feature is implemented, a RAILtest serial command is added to allow scripted testing and ad hoc experimentation. Many of the RAILtest serial commands can be used for lab evaluation.
RAILtest includes commands to:
Transmit and receive packets. Schedule transmits at a specific time in the RAIL timebase.

៥/៥

Proprietary Flex SDK Product Overview
Configure RAIL address filtering to receive only specific packets. Enable CCA mechanisms (CSMA/LBT) to validate that a channel is clear before transmit. Set a timer callback in the RAIL timebase to see how the RAIL timer API works. Change the transmit channel within the current configuration’s band. Change the transmit power level. Enable RF energy sensing of specified duration across the 2.4 GHz and/or Sub-GHz bands, and sleep to wake on this event. Output a continuous unmodulated tone for debugging. Output a continuous modulated PN9 stream for debugging. Enter into direct mode where data can be sent and received using asynchronous GPIOs as input and output.
RAIL SoC Range Test
The Range Test examples enable over-the-air range testing between two devices customized with user-defined parameters. Range Test is designed to be run on Silicon Labs hardware without the need for commands from a host computer. This capability allows for mobility during range testing activities.
RAIL SoC Range Test BLE and IEEEE80215.4
The Range Test examples enable over-the-air range testing between two devices customized with user-defined parameters. Five predefined PHYs can be used: BLE: 125kbps, BLE: 500kbps, BLE: 1Mbps, BLE: 2Mbps, IEEE80215.4: 250kbps.
RAIL SoC Switch: Demonstrates the simplest exchange of transmit and receive operation between a light and a switch.

រចនាសម្ព័ន្ធគម្រោង
Projects always include the following parts:
autogen folder: Only the autogen folder includes generated code. It includes the PHY configuration (rail_config.c), init code, the linker script, and other generated code used by components, like the command descriptors for the CLI interface. config folder: Component configuration headers are located in this folder. These can be edited with the Simplicity IDE Component Editor, but directly editing the header file is also possible. The Component Editor is available through the Project Configurator’s Configure control, available only for configurable components. gecko_sdk folder (with version number): Contains source and binary files added by components. files in the root folder: Only the application specific files should be in the root folder, including source files, the project configurator (.slcp) file and the Pin Tool (.pintool) file.

All projects include main.c, which is not recommended to modify. Instead, add the initialization code to app_init.c, and implement the main loop in app_process.c. This way, the System components can initialize components, and call the “process” function of the components that require it. Additionally, enabling an RTOS will convert app_process’s main loop into an RTOS task.
ទាំងនេះ files are also available in Connect projects, and can be used for example for init and process tasks that are independent of the stack running or not. However, it is still recommended to use emberAfInitCallback() and emberAfTickCallback(), so the Connect stack could prioritize urgent stack operations above the application.
The Gecko Bootloader
A bootloader is a program stored in reserved flash memory that can initialize a device, update firmware images, and possibly perform some integrity checks. Silicon Labs networking devices use bootloaders that perform firmware updates in two different modes: standalone (also called standalone bootloaders) and application (also called application bootloaders). An application bootloader performs a firmware image update by reprogramming the flash with an update image stored in internal or external memory. For more information about bootloaders see UG103.6: Bootloader Fundamentals.
The Gecko Bootloader is a code library configurable through Simplicity Studio’s IDE to generate bootloaders that can be used with a variety of Silicon Labs protocol stacks. The bootloaders work with specialized firmware update image formats. The Gecko Bootloader update images has the extension .gbl.
Examples provided for the EFR32 parts include Silicon Labs Gecko Bootloader examples ។ ឧamples are provided for all compatible Simplicity Studio SDKs. For more information on using the Gecko Bootloader see UG266: Silicon Labs Gecko Bootloader User’s Guide in GSDK 3.2 and Lower and Silicon Labs Gecko Bootloader User’s Guide for GSDK 4.0 and Higher.

Proprietary Flex SDK Product Overview
Note: When working with the Gecko Bootloader, you must use Simplicity Commander to enable some configuration options such as security features.
Gecko Platform
The Gecko Platform is a set of drivers and other lower layer features that interact directly with Silicon Labs chips and modules. Gecko Platform components include EMLIB, EMDRV, RAIL Library, NVM3, and mbedTLS. For more information about Gecko Platform, see release notes that can be found in Simplicity Studio’s Documentation tab.

The Packet Trace application captures the packets directly from the Packet Trace Interface (PTI) available on the Wireless Gecko SoCs and modules. It therefore provides a more accurate capture of the packets compared to air-based capture.
