Software for sticks and modules based on the Silicon Labs EFR32MG21 chip

Note: Third party firmware may not be compatible or supported by JetHome devices. Therefore, JetHome devices are not guaranteed to work with third-party firmware. Use only the firmware recommended below.

To work with the Zigbee protocol for JetStick Z4 sticks and modules, it is recommended to use the following firmware:


Zigbee coordinator firmware . Based on Silicon Labs EZSP Coordinator v8 software. To flash via the UART bootloader, use the file named  z4-ncp-uart-sw-*.gbl

This firmware adds support for two LEDs to indicate stick operation modes: the green LED blinks in the mode of connecting new Zigbee devices; the red LED blinks when data is received.

UART parameters:

  • Working speed 57600 or 115200 bps (specified in the firmware file name). If baud rate is not specified, 115200 bps is used;
  • Firmware files with "sw" in the file name use XON/XOFF software flow control.
