+# OpenThread on EFR32MG13 Example
+
+This directory contains example platform drivers for the [Silicon Labs EFR32MG13][efr32mg13]
+based on [EFR32™ Mighty Gecko Wireless Starter Kit][SLWSTK6000B].
+
+[efr32mg]: http://www.silabs.com/products/wireless/mesh-networking/efr32mg-mighty-gecko-zigbee-thread-soc
+[SLWSTK6000B]: http://www.silabs.com/products/development-tools/wireless/mesh-networking/mighty-gecko-starter-kit
+
+The example platform drivers are intended to present the minimal code
+necessary to support OpenThread. [EFR32MG13P SoC][efr32mg13p]
+has rich memory and peripheral resources which can support all OpenThread
+capabilities. See the "Run the example with EFR32MG13 boards" section below
+for an example using basic OpenThread capabilities.
+
+See [sleepy-demo/README.md](sleepy-demo/README.md) for instructions for an example that uses the low-energy
+modes of the EFR32MG13 when running as a Sleepy End Device.
+
+[efr32mg13p]: http://www.silabs.com/products/wireless/mesh-networking/efr32mg-mighty-gecko-zigbee-thread-soc/device.EFR32MG13P432F1024GL125
+
+## Toolchain
+
+Download and install the [GNU toolchain for ARM Cortex-M][gnu-toolchain].
+
+[gnu-toolchain]: https://developer.arm.com/open-source/gnu-toolchain/gnu-rm
+
+In a Bash terminal, follow these instructions to install the GNU toolchain and
+other dependencies.
+
+```bash
+$ cd <path-to-openthread>
+$ ./script/bootstrap
+```
+
+## Build Examples
+
+1. Download and install the [Simplicity Studio][simplicity_studio].
+
+[simplicity_studio]: http://www.silabs.com/products/development-tools/software/simplicity-studio
+
+2. Install Flex (Gecko) SDK including RAIL Library from Simplicity Studio.
+   - Connect EFR32MG13P Wireless Starter Kit to Simplicity Studio.
+   - Find Flex SDK v2.7 in the Software Update page and click Install.
+   - Flex SDK v2.7 will be installed in the path: `/SimplicityStudio_v4/developer/sdks/gecko_sdk_suite`.
+
+For more information on configuring, building, and installing applications for the Wireless Gecko (EFR32)
+portfolio using FLEX, see [Getting Started with the Silicon Labs Flex Software Development Kit for the 
+Wireless Gecko (EFR32™) Portfolio][QSG138]. For more information
+on RAIL, see [Radio Abstraction Interface Layer][rail].
+
+[QSG138]: https://www.silabs.com/documents/public/quick-start-guides/qsg138-flex-efr32.pdf
+[rail]: http://www.silabs.com/products/development-tools/software/radio-abstraction-interface-layer-sdk
+
+3. Configure the path to Flex SDK source code.
+```bash
+$ cd <path-to-openthread>/third_party
+$ mkdir silabs
+$ cd <path-to-Simplicity-Studio>/developer/sdks
+$ cp -rf gecko_sdk_suite <path-to-openthread>/third_party/silabs/
+```
+
+Alternatively create a symbolic link to the Flex SDK source code.
+```bash
+$ cd <path-to-openthread>/third_party
+$ mkdir silabs
+$ ln -s <path-to-Simplicity-Studio>/developer/sdks/gecko_sdk_suite silabs/gecko_sdk_suite
+```
+
+4. Build OpenThread Firmware (CLI example) on EFR32 platform.
+```bash
+$ cd <path-to-openthread>
+$ ./bootstrap
+```
+For EFR32MG13™ Mighty Gecko Wireless Starter Kit:
+```bash
+$ make -f examples/Makefile-efr32mg13 BOARD=BRD4168A
+```
+
+After a successful build, the `elf` files are found in
+`<path-to-openthread>/output/efr32mg13/bin`.
+
+## Flash Binaries
+
+Compiled binaries may be flashed onto the EFR32 using [JLinkGDBServer][jlinkgdbserver].
+EFR32 Starter kit mainboard integrates an on-board SEGGER J-Link debugger.
+
+[jlinkgdbserver]: https://www.segger.com/jlink-gdb-server.html
+
+```bash
+$ cd <path-to-JLinkGDBServer>
+$ sudo ./JLinkGDBServer -if swd -device EFR32MG13PxxxF1024
+$ cd <path-to-openthread>/output/efr32/bin
+$ arm-none-eabi-gdb ot-cli-ftd
+$ (gdb) target remote 127.0.0.1:2331
+$ (gdb) load
+$ (gdb) monitor reset
+$ (gdb) c
+```
+
+Note: Support for the "EFR32MG13PxxxF1024" device was added to JLinkGDBServer V6.14d.
+
+Or 
+Compiled binaries also may be flashed onto the specified EFR32 dev board using [J-Link Commander][j-link-commander].
+
+[j-link-commander]: https://www.segger.com/products/debug-probes/j-link/tools/j-link-commander/
+
+```bash
+$ cd <path-to-openthread>/output/efr32mg13/bin
+$ arm-none-eabi-objcopy -O ihex ot-cli-ftd ot-cli-ftd.hex
+$ JLinkExe -device EFR32MG13PxxxF1024 -speed 4000 -if SWD -autoconnect 1 -SelectEmuBySN <SerialNo>
+$ J-Link>loadfile ot-cli-ftd.hex
+$ J-Link>r
+$ J-Link>q
+```
+
+Note: SerialNo is J-Link serial number. Use the following command to get the serial number of the connected J-Link.

+```bash
+$ JLinkExe
+```
+
+Alternatively Simplicity Commander provides a graphical interface for J-Link Commander.
+
+```bash
+$ cd <path-to-openthread>/output/efr32mg13/bin
+$ arm-none-eabi-objcopy -O ihex ot-cli-ftd ot-cli-ftd.ihex
+$ <path-to-simplicity-studio>/developer/adapter_packs/commander/commander
+```
+
+In the J-Link Device drop-down list select the serial number of the device to flash.  Click the Adapter Connect button.
+Esnure the Debug Interface drop-down list is set to SWD and click the Target Connect button.
+Click on the Flash icon on the left side of the window to switch to the flash page.
+In the Flash MCU pane enter the path of the ot-cli-ftd.s37 file or choose the file with the Browse... button.
+Click the Flash button located under the Browse... button.
+
+## Run the example with EFR32MG13 boards
+1. Flash two EFR32 boards with the `CLI example` firmware (as shown above).
+2. Open terminal to first device `/dev/ttyACM0` (serial port settings: 115200 8-N-1).
+   Type `help` for a list of commands.
+
+   ```bash
+   > help
+   help
+   channel
+   childtimeout
+   contextreusedelay
+   extaddr
+   extpanid
+   ipaddr
+   keysequence
+   leaderweight
+   masterkey
+   mode
+   netdataregister
+   networkidtimeout
+   networkname
+   panid
+   ping
+   prefix
+   releaserouterid
+   rloc16
+   route
+   routerupgradethreshold
+   scan
+   start
+   state
+   stop
+   whitelist
+   ```
+
+3. Start a Thread network as Leader.
+
+   ```bash
+   > dataset init new
+   Done
+   > dataset
+   Active Timestamp: 1
+   Channel: 13
+   Channel Mask: 07fff800
+   Ext PAN ID: d63e8e3e495ebbc3
+   Mesh Local Prefix: fd3d:b50b:f96d:722d/64
+   Master Key: dfd34f0f05cad978ec4e32b0413038ff
+   Network Name: OpenThread-8f28
+   PAN ID: 0x8f28
+   PSKc: c23a76e98f1a6483639b1ac1271e2e27
+   Security Policy: 0, onrcb
+   Done
+   > dataset commit active
+   Done
+   > ifconfig up
+   Done
+   > thread start
+   Done
+
+   wait a couple of seconds...
+
+   > state
+   leader
+   Done
+   ```
+
+4. Open terminal to second device `/dev/ttyACM1` (serial port settings: 115200 8-N-1)
+   and attach it to the Thread network as a Router.
+
+   ```bash
+   > dataset masterkey dfd34f0f05cad978ec4e32b0413038ff
+   Done
+   > dataset commit active
+   Done
+   > routerselectionjitter 1
+   Done
+   > ifconfig up
+   Done
+   > thread start
+   Done
+
+   wait a couple of seconds...
+
+   > state
+   router
+   Done
+   ```
+
+5. List all IPv6 addresses of Leader.
+
+   ```bash
+   > ipaddr
+   fd3d:b50b:f96d:722d:0:ff:fe00:fc00
+   fd3d:b50b:f96d:722d:0:ff:fe00:c00
+   fd3d:b50b:f96d:722d:7a73:bff6:9093:9117
+   fe80:0:0:0:6c41:9001:f3d6:4148
+   Done
+   ```
+
+6. Send an ICMPv6 ping to Leader's Mesh-EID IPv6 address.
+
+   ```bash
+   > ping fd3d:b50b:f96d:722d:7a73:bff6:9093:9117
+   16 bytes from fd3d:b50b:f96d:722d:558:f56b:d688:799: icmp_seq=1 hlim=64 time=24ms
+   ```
+
+The above example demonstrates basic OpenThread capabilities. Enable more features/roles (e.g. commissioner,
+joiner, DHCPv6 Server/Client, etc.) by assigning compile-options before compiling.
+
+```bash
+$ cd <path-to-openthread>
+$ ./bootstrap
+$ make -f examples/Makefile-efr32mg13 COMMISSIONER=1 JOINER=1 DHCP6_CLIENT=1 DHCP6_SERVER=1
+```

+
+# EFR32MG13 Sleepy Demo Example
+
+The EFR32 Sleepy applications demonstrates Sleepy End Device behaviour using
+the EFR32's low power EM2 mode. The steps below will take you through the
+process of building and running the demo
+
+For setting up the build environment refer to [examples/platforms/efr32mg13/README.md](../README.md).
+
+
+## 1. Build
+
+```bash
+$ cd <path-to-openthread>
+$ ./bootstrap
+$ make -f examples/Makefile-efr32mg13 COMMISSIONER=1 JOINER=1 DHCP6_CLIENT=1 DHCP6_SERVER=1 BOARD=BRD4168A
+```
+
+Convert the resulting executables into S-Record format and append a s37 suffix.
+
+```bash
+$ cd output/efr32mg13/bin
+$ arm-none-eabi-objcopy -O srec sleepy-demo-mtd sleepy-demo-mtd.s37
+$ arm-none-eabi-objcopy -O srec sleepy-demo-ftd sleepy-demo-ftd.s37
+```
+
+In Silicon Labs Simplicity Studio flash one device with the sleepy-demo-mtd.s37
+image and the other device with the sleepy-demo-ftd.s37 image.
+
+For instructions on flashing firmware see [examples/platforms/efr32mg13/README.md](../README.md#flash-binaries)
+
+
+## 2. Starting nodes
+
+For demonstration purposes the network settings are hardcoded within the source files.
+The devices start Thread and form a network within a few seconds of powering on. In a real-life
+application the devices should implement and go through a commissioning process to create
+a network and add devices.
+
+When the sleepy-demo-ftd device is started in the CLI the user shall see:
+
+```
+sleepy-demo-ftd started
+sleepy-demo-ftd changed to leader
+```
+
+When the sleepy-demo-mtd device starts it joins the preconfigured Thread network
+before disabling Rx-On-Idle to become a Sleepy-End-Device.
+
+Use the command "child table" in the FTD console and observe the R flag of the child is 0.
+
+```
+> child table
+| ID  | RLOC16 | Timeout    | Age        | LQ In | C_VN |R|S|D|N| Extended MAC     |
++-----+--------+------------+------------+-------+------+-+-+-+-+------------------+
+|   1 | 0x8401 |        240 |          3 |     3 |    3 |0|1|0|0| 8e8582dbd78c243c |
+
+Done
+```
+
+
+## 3. Buttons on the MTD
+
+Pressing button 0 on the MTD toggles between operating as a Minimal End Device (MED) and
+a Sleepy End Device (SED) with the RX off when idle.
+
+Pressing button 1 on the MTD sends a multicast UDP message containing the
+string "mtd button".  The FTD listens on the multicast address and will toggle
+LED 0 and display a message in the CLI showing "Message Received: mtd button".
+
+## 4. Buttons on the FTD
+
+Pressing either button 0 or 1 on the FTD will send a UDP message to the FTD containing the string
+"ftd button". The MTD must first send a multicast message by pressing the MTD's button 1 so that
+the FTD knows the address of the MTD to send messages to.
+
+This will toggle the state of LED0 on the MTD.  If the MTD is operating as a sleepy end device then
+the MTD polls the parent every 5 seconds for messages and will update the LED state on the
+next poll.
+
+## 5. Monitoring power consumption of the MTD
+
+Open the Energy Profiler within Silicon Labs Simplicity Studio.  Within the Quick Access menu
+select Start Energy Capture... and select the MTD device.  When operating as a Sleepy End Device
+with no LEDs on the current should be under 20 microamps with occassional spikes during waking
+and polling the parent.  With the LED on the MTD has a current consumption of approximately 1mA.
+
+When operating as a Minial End Device with the Rx on Idle observe that the current is in the order
+of 10ma.
+
+With further configuration of GPIOs and peripherals it is possible to reduce the sleepy current
+consumption further.
+
+## 6. Notes on sleeping, sleepy callback and interrupts
+
+To allow the EFR32 to enter sleepy mode the application must register a callback with efr32SetSleepCallback.
+The return value of callback is used to indicate that the application has no further work to do and that
+it is safe to go into a low power mode.  The callback is called with interrupts disabled so should do
+the minimum required to check if it can sleep.
