Simplicity Commander is a software package provided by Silicon Labs that provides a very powerful GUI and command line utility for working with your EFR32 parts.  With Simplicity Commander you can flash firmware (bootloaders and applications), update the WSTK firmware, reset locked parts and unlock debug access.  It is the EFR32 version of the ISA3 Utilites.

Standalone Installation 

As of 7/2017, Simplicity Commander is now available as a standalone utility (in addition to the Simplicity Studio-based install/launch options listed below).  See the download links listed under the "In-System Programming" section at Production Programming Options for Silicon Labs Devices.  Installers and release notes are available for Windows, Mac, and Linux.  

See the included README.txt for additional guidance and dependencies (Commander currently requires the SEGGER J-Link software pack to be installed).

Launching the GUI

In Studio v3.3, if wireless support is installed, Simplicity Commander will be available from the "File -> Simplicity Commander" menu in the IDE.

In Studio v4 the commander binary can be run by going to Preferences -> Simplicity Studio -> Adapter Packs, selecting Simplicity Commander -> commander: commander.exe and clicking on "Bare run".

Launching the Command Line Utility

In Studio v4, along with the GUI in the above commands, the bare run window can be used to launch the command line utility as well.  You can enter additional parameters on the executable line after the command: 

C:\SiliconLabs\SimplicityStudio\v4\developer\adapter_packs\commander\commander.exe

An option like --version will give you the version and --help will give additional commands.

From the command line, you can run Simplicity Commander directly.  In v3 it can be found at:

C:\SiliconLabs\SimplicityStudio\v3\SimplicityCommander\commander.exe

and in v4, it can be found at:

C:\SiliconLabs\SimplicityStudio\v4\developer\adapter_packs\commander\commander.exe

For ease of use, you can add either of these directories to your path (minus commander.exe) and run Simplicity Commander by just invoking the following at the command prompt:

commander

 For additional use of Commander, refer to:

UG162 Simplicity Commander Reference Guide

When building host applications in a Linux environment (this includes Cygwin) you need to have all of the following libraries otherwise your build will fail with errors.

• Make
• GCC
• sed
• awk
• xargs
• The standard C Library and its development headers
• The Readline Library and its development headers (optional)
• The Ncurses Library and its development headers (optional - only needed to support Readline)

Should you encounter build errors when attempting to make a Linux based host application, make sure these libraries are installed.

Within our EmberZNet and Silicon Labs Thread stacks we provide a number of pre-built NCP images. However, with the customability EFR32 Mighty Gecko, these NCP images don't always meet every application. This guide, along with reading AN1010: Building a Customized NCP Application, should give you the tools to build your own xNCP image.

1. Go to File -> New -> Project. This will bring up the New Project Wizard
2. Select “Silicon Labs Thread”. Click Next. 
3. Select the Stack you want to use. Click Next.
   (Note, these step by step instructions assume using Thread 2.0 or later)
4. Thread offers 3 NCP options here, NCP SPI, NCP UART (Software Flow Control), and NCP UART (Hardware Flow Control). Pick the option which matches your application. Click Next.
5. Give your project a name, leave it in the default location. Click Next.
6. On the Project Setup Window pick the BRD4151A board (it will pick the EFR321P232F256GM48 chip). We will change this later, we are just using this to start the project. Hit Finish.
7. Download and copy the xNCP_board.h file to your project (you can drag and drop it into your Project in Studio, when prompted, make sure to Copy the file into your project).
8. On the General Tab
   
   • Selected Architecture – pick the chip you are using
9. On the HAL Tab
   
   • Change Board Header from Default to Use Custom Board Header
   • Point the Custom Board Header to xNCP_board.h (it should be in your Studio v4 Workspace
   • Verify that your Bootloader is set to Standalone.
10. On the Plugins Tab
    
    • Verify in the HAL section that the NCP type matches the version you are using, either NCP UART Link or NCP SPI Link
      (Because you have selected your NCP type earlier, this should be set)
11. On the Other Tab
    
    • In the Additional .c and .h files section Add the following directories:
      

      <PATH_TO_STACK_FOLDER_ROOT>\hardware\kit\EFR32MG1_BRD4151A\config
      <PATH_TO_STACK_FOLDER_ROOT>\hardware\kit\common\bsp

12. Open the xNCP_board.h file
    
    • Find the #define statements for which build to use
      

      #define UART_XNCP_BUILD
      #define SPI_XNCP_BUILD

      Comment out the one you aren’t using and make sure the one you need is defined
    • Modify the section to match the pins you have selected. You must get the _USART_ROUTELOC0_ definitions from the EFR32MG1 Mighty Gecko Data Sheet, Pages 139-140.
    • Once the modifications are made, save the file
13. Generate the files for your project
14. Build your project

 Use the following KBA for building a bootloader:

This article covers migrating from an old EmberZNet stack version to a current version (pre-EmberZNet5.8) using Simplicity Studio v4 and your project's ISC file.

1. Copy the ISC file and any additional files in the project that were modified into the same directory. For example:

./Gismo1Migrate/Gismo1.isc
./Gismo1Migrate/Gismo1_callbacks.c
./Gismo1Migrate/Gismo1_peripherals.c
./Gismo1Migrate/Gismo1_peripherals.h
./Gismo1Migrate/Gismo1_board.h

2. Start up Studio v4 and go to the Simplicity IDE perspective.
3. Go to Window -> Preferences -> Simplicity Studio -> SDKs and uncheck all EmberZNet stack installs other than the most current EmberZNet stack you are migrating to.
4. Go to File -> Import and select Simplicity Studio -> MCU Project. This will open up a dialogue.
4. Find your ISC file and add it to the list. Click Next and the Build Configuration will show that there or some unresolved dependencies. Click Next again to make changes.
5. Under Reconstruct Build Configurations make sure you have the proper Board (if you have one), Part, SDK, and Toolchain are selected. Click Next.
6. Under Project Configuration, type in a Project name. Click Finish.
7. Navigate to your project in Project Explorer and open your ISC file. Simplicity Studio might ask you to select the specific stack you want to use. This is because of the differences between Host and SoC code. After this, an "Auto upgrade notice" should pop up. Closing this window, your project has been updated to the new stack you have available.
8. Under the General tab, check the stack version and generation directory.
8. Navigate to the "Other" tab in AppBuilder and update any additional files added by clicking on the file and reselecting it.
9. Generate.
10. Compile.

A step-by-step guide to creating, building, and running your own Router Eligible End Device (REED) application based on the Silicon Labs Thread stack. This tutorial expands on Part 2 by adding a button event for the LED toggle and capturing the associated network traffic.

This tutorial is part of a three part series:

Building a Thread Router Eligible End Device Application Part 1.

Building a Thread Router Eligible End Device Application Part 2.

Building a Thread Router Eligible End Device Application Part 3.

Requirements:

Software:
 - Simplicity Studio v4
 - Silicon Labs Thread Stack 2.0.0
 - IAR Workbench 7.30
 - Generated project for Router Eligible End Device.

Hardware:
 - EFR32MG Wireless Starter Kit (WSTK)

I. Updating Configuration for the Reed
  1. Go back to the ISC configuration file we have been working on (ThreadReed200EFR32).
  2. Navigate to the "Callbacks" tab.
      a. Select "halButtonIsr".
  3. Under the "Other" tab:
      a. Add an Event item under Event Configuration section. This will link an event to a button press.
          i. Set Command to "eventToggle".
          ii. Set Callback to "eventToggleHandler".
  4. Click "Generate". AppBuilder will ask you to validate the generation to make sure which files can be overwritten. Make sure thread-callbacks.c is UNCHECKED. Click OK.
  5. In the "Generation successful" window click OK.
  6. Save the ISC file.

II. Add Code and Build Project in Simplicity Studio IDE
  1. In thread-callbacks.c add the following code to have the node send out a CoAP Broadcast message.

static const EmberIpv6Address allMeshNodes = {
  {0xFF, 0x03, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
   0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01,}
};

static const uint8_t reedToggleUri[] = "reed/toggle";
EmberEventControl eventToggle;

void eventToggleHandler(EmberStatus status) {
  emberEventControlSetInactive(eventToggle);
 
  halToggleLed(BOARD_ACTIVITY_LED);
 
  emberAfCorePrintln("Broadcast to ");
  emberAfCoreDebugExec(emberAfPrintIpv6Address(&allMeshNodes));
  emberAfCorePrintln("");  
 
  status = emberCoapPostNonconfirmable(&allMeshNodes,
                                       reedToggleUri,
                                       NULL, // body
                                       0);   // body length
}

 2. In thread-callbacks.c add interrupt service routine for the button state.

void halButtonIsr(uint8_t button, uint8_t state) {
 if ((state == BUTTON_PRESSED) && (button == BUTTON0)) {
   emberEventControlSetDelayMS(eventToggle, 10);
 }
}

 3. Compile your project and Ensure that the build completes with zero errors.

III. Load Application to All WSTKs
  1. In Network Analyzer perspective, click on a node for your application and select "Flash/Upload".
  2. Upload only the updated application. This time DO NOT erase the chip because we want to keep the network parameters saved in non-volatile memory.
  3. Repeat for all nodes.

IV. Capture Network Traffic
  1. Set Network Analyzer decode to the appropriate Thread stack by going to Window -> Preferences -> Network Analyzer -> Decoding -> Stack Versions. (Please note, there is an auto-detection decoder stack however, if you have multiple protocols in the air in your space, then we recommend selecting the specific stack).
  2. Make sure your master-key is available in Window -> Preferences -> Network Analyzer -> Decoding -> Security Keys. If it is not there add a new security key by clicking on the "Add" button.
  3. In Network Analyzer perspective, in the Device view, right-click on a node and select "Start capture with options"
      a. May need to select "Connect" first if icon beside node name is not showing green.
  4. In capture options specify PAN ID. This allows you to narrow the data captured to the specific PAN ID.

V. Bringing the Reed Back into Network
  1. In console bring the node back up by using the resume command.

network-management resume

  2. Do this for all nodes. Management traffic should start showing in the network capture.

VI. Sending Messages
  1. Press Button0 on WSTK board. Console will print when the node is broadcasting. Nodes with URI "reed/toggle", will toggle their LEDs. The network capture will show CoAP messages.

A step-by-step guide to creating, building, and running your own Router Eligible End Device (REED) application based on the Silicon Labs Thread stack. This tutorial expands on Part 1 by adding a handler for a CoAP message.

This tutorial is part of a three part series:

Building a Thread Router Eligible End Device Application Part 1.

Building a Thread Router Eligible End Device Application Part 2.

Building a Thread Router Eligible End Device Application Part 3.

Requirements:

Software:
 - Simplicity Studio v4
 - Silicon Labs Thread Stack 2.0.0
 - IAR Workbench 7.30
 - Generated project for Router Eligible End Device.

Hardware:
 - EFR32MG Wireless Starter Kit (WSTK)

I. Updating Configuration for REED
  1. Go back to the ISC configuration file which we created in the previous exercise (ThreadReed200EFR32.isc).
  2. Navigate to the "Plugins" tab:
      a. Select "CoAP Dispatch".
        b. Remove "CoAP Debug" as there are some conflicts.
  3. Under the "Other" tab:
      a. Add a CoAP Dispatch item.
          i. Change Method to POST.
          ii. Change URI Path to "reed/toggle".
          iii. Change Handler to "reedToggleHandler".
  4. Click "Generate". AppBuilder will ask you to validate the generation to make sure which files can be overwritten. Make sure thread-callbacks.c is unchecked. Click OK.
  5. In the "Generation successful" window click OK.
  6. Save the ISC file.

II. Add Code and Build Projects in Simplicity Studio IDE
  1. In thread-callbacks.c add the following code to have the node respond to CoAP messages. This Handler will respond to "reed/toggle" URI, toggle an LED on the WSTK, and print a statement to the console.

void reedToggleHandler(void) {
  EmberCoapCode responseCode;
 
  halToggleLed(BOARD_ACTIVITY_LED);

  responseCode = EMBER_COAP_CODE_204_CHANGED;
  emberCoapRespond(responseCode, NULL, 0);
 
  emberSerialPrintf(APP_SERIAL, "\nToggled LED\n");
}

  2. Build your project and ensure that it completes with zero errors.

III. Load Application to All WSTKs
  1. In Network Analyzer perspective, click on a node for your application and disconnect from the device (for the EFR32). Then select "Flash/Upload".
  2. Upload only the updated application. This time DO NOT erase the chip because we want to keep the network parameters saved in non-volatile memory.
  3. Repeat for all nodes.

IV. Bringing Nodes Back Into the Network
  1. In Network Analyzer perspective, navigate to the node's console and use the resume command.

network-management resume

  2. Do this for all nodes.

V. Sending CoAP messages
  1. In the console send a CoAP POST message to your neighbor using their IP address and unique URI to toggle the LED using coap post <destination> <uri> <body>

coap post "fd00:db8::d9dd:b493:143b:9cbc" "reed/toggle" "1"
