Hello,
Could you please take a look at this community thread?
Also, we highly recommend moving to the JN5189 Wireless MCU for Zigbee® and Thread, as is our focus part for ZigBee/Thread. It is supported by our MCUXpresso IDE and MCUXpresso SDK. There are several SDK examples, like driver examples (GPIO, UART, SPI, I2C), RTOS examples, and Wireless examples (ZigBee and Thread).
Regards,
Ricardo
