[ Edited ]

On March 14th 2017, Silicon Labs released new SoCs to widen its Wireless Gecko portfolio with the new EFR32xG12 devices supporting Bluetooth 5 features, with larger memory options, enhanced cryptography acceleration support for multiprotocol to name a few of the new features. The EFR32xG12 devices are available for order. Please check the device specs from the press release and the product pages.



Together with new devices we released new version of the Bluetooth SDK v2.3.0.0, as part of the Gecko Suite SDK v1.0.0.0. The SDK added support to newly released products, but also added features like:

* Switched multiprotocol between Bluetooth and zigbee
* Bluetooth 5.0: 2M PHY support for EFR32BG12/MG12
* Bluetooth 5.0: Advertisement sets support
* Bluetooth 4.2: 250B ATT MTU and 128B link layer packet support
* EFR32BG12MG12 hardware support
* Gecko Bootloader support
* GCC compiler support (Beta)


Get your hands on the new SDK by downloading or upgrading to the latest Simplicity Studio v4 and using the package manager to download the Bluetooth Smart SDKv2.3.0.0.
