Introduction

The Silicon Labs Examples in Simplicity Studio are very easy to access: You connect your Starter Kit and Simplicity Studio will display the list of examples as shown below:

We hope that you can find the most appropriate example to test your starter kit and hopefully base your design from one of the examples featured in Simplicity Studio.

But, in case you can’t find the example you were looking for, we have a wide variety of unpublished examples in a public repository. Like when you go to a store and ask one of the store's employees to see if the item you want is in the "back room" because you couldn’t find it on the shelves; The Silicon Labs back room for those examples you couldn’t find as part of Simplicity Studio is our repository in GitHub:

https://github.com/SiliconLabs

There you will find examples for pretty much all the Silicon Labs devices.

In this blog, I will show you how to access the EFM32/EFR32 Peripheral Examples.

EFM32/EFR32 Peripheral Examples

This repository contains low-level examples for each peripheral on the EFM32 and EFR32 devices:

https://github.com/SiliconLabs/peripheral_examples

The examples are organized by Series and then by Peripheral name as illustrated in Figure 2:

Device Series

If you want to find out what Series is your device, you can look at the package marking and the number highlighted in the table below is the series number:

Table 1 Devices by Series

Peripheral Name

The table below lists all the device peripherals along with their description:

Table 2 Device Peripherals

Accessing the Peripheral Examples

To access the peripheral examples take the following steps:

Clone or Download the repository to the following path in your Simplicity Studio installation:

C:\SiliconLabs\SimplicityStudio\v4\developer\sdks\gecko_sdk_suite\v#.#\app\

where #.# is the Gecko SDK suite version number

Import the example you want from Simplicity Studio by making one of the following series of clicks:

File -> Import, or

Project -> Import -> MCU Project

To access the examples from IAR, simply navigate to the desired .slsproj file and double click on it.

Last week, the Bluetooth SIG announced to its members an update about security vulnerability related to the encryption key negotiation protocols. According to the SIG, researchers of SUTD, CISPA and Oxford University identified a vulnerability with the encryption key negotiation protocol of Bluetooth BR/EDR. The attack makes it possible for a third party to make the victims to agree on an encryption key with only 1 byte (8 bits) of entropy, which then enables the attacker to brute force the negotiated encryption keys, decrypt the eavesdropped ciphertext, and inject valid encrypted messages in real-time. The attack is standard-compliant because all Bluetooth BR/EDR versions require to support encryption keys with entropy between 1 and 16 bytes and do not secure the key negotiation protocol. (More information about the details of the attack for example here www.knobattack.com)

Our Wireless Gecko Bluetooth products (Blue Gecko) and BLE112, BLE113, BLE113, BLE121LR and BLED112 module products are not affected by this issue because they are based on Bluetooth LE core specification which does not have this vulnerability.

Our Bluetooth BR/EDR (BT Classic) products, which include the WT12, WT11u, WT41u, WT32, WT32i, BT111 and BT121 modules, are vulnerable to this issue. We plan to release a patches which protect against this vulnerability during October 2019
