Sonoff ZBDongle-E is based on the EFR32MG21 Multiprotocol SoC chip, it’s capable of both Zigbee and Thread communication thanks to the radio of the module.

Flashing the Sonoff ZBDongle-E
This custom firmware was developed by darkxst (Tim L) and works for Home Assistant Yellow and SkyConnect, Sonoff ZBDongle-E and EasyIot ZB-GW04 v1.1/v1.2.

SILICON LABS的SoC EFR32MG21可应用于Matter网关的应用中，在这样的应用中EFR32MG21中运行的是射频协处理器（RCP）功能的软件，EFR32MG21 USB Stick就是实现这个功能的硬件，这个硬件是通过CP2102 USB转UART的芯片与主机通信，将烧录有RCP程序的USB Stick接到树莓派上就可以方便的实现Matter的边界路由或网桥功能。USB Stick中已经预先烧录了X-Modem Bootloader软件，EFR32MG21的程序可以直接通过X-Modem文件传输协议升级RCP固件。



通过X-Modem升级时首先要让EFR32MG21进入BootLoader状态，USB Stick是通过CP2102的DTR/RTS两个引脚的控制芯片复位并进入BootLoader状态。所以更新RCP程序的软件要有控制DTR/RTS信号的功能。



我们在更新EFR32MG21的RCP程序时可以选择在Windows或Linux(包括树莓派)的环境下升级。
