As a homeowner who’s always on the lookout for ways to enhance my smart home setup, I recently embarked on a project to set up a Zigbee coordinator on my Thingy:91_nrf52840 board. My goal was to create a system that could receive reports from end devices and publish the values to the cloud. While I had some success with a coordinator sample on the nRF5340DK, porting it to the nRF52840 proved to be quite the challenge.
Initially, I tried enabling Zigbee by simply setting CONFIG_ZIGBEE=y, but this resulted in errors during the build process. After some research, I realized that the hardware files weren’t configured to support Zigbee on this board. This was a bit disheartening, but I knew I had to dig deeper.
I decided to explore the configuration files and documentation to understand what changes were necessary. It turns out that enabling Zigbee required more than just a simple flag—it needed proper hardware configuration and possibly some custom firmware adjustments. I spent hours tweaking the settings and testing each change, but the results were inconsistent.
Despite the challenges, I remained determined. I reached out to the Nordic Semiconductor community for guidance, and their support was invaluable. They provided insights into the specific configurations needed for the nRF52840 and pointed me toward resources that helped me understand the hardware limitations better.
After several iterations of testing and tweaking, I finally managed to get the Zigbee coordinator working on my Thingy:91_nrf52840. The sense of accomplishment was immense, and it reinforced my belief in the importance of perseverance in tech projects. This experience not only taught me a lot about Zigbee and embedded systems but also gave me the confidence to tackle more complex projects in the future.
For anyone else looking to set up a Zigbee coordinator on a similar board, my advice is to start with a thorough understanding of the hardware requirements and to leverage community resources for support. It’s a challenging but rewarding endeavor, and the end result is well worth the effort.
