The nRF7002 Development Kit (DK) has been a game-changer in my journey with Wi-Fi 6, especially with its support for Target Wake Time (TWT). TWT is a feature that allows devices to negotiate wake-up times with the access point, significantly reducing power consumption. I recently dove into setting this up and wanted to share my experience and tips for others looking to optimize their devices.After setting up the Wi-Fi Shell sample as outlined in the Nordic documentation, I started experimenting with different TWT intervals. The process was straightforward—using the wifi twt setup command with varying wake intervals. However, I encountered a hiccup when my router didn’t seem to respond as expected. It turned out that ensuring TWT was enabled on the router was crucial. Once that was sorted, the setup worked seamlessly.One thing I found fascinating was observing the power consumption metrics using the Power Profiler Kit II. With a 10-minute TWT interval, the average current dropped to just 24 uA, which is impressive. This setup is perfect for devices that don’t need constant connectivity, like sensors in a smart home setup.I also reached out to the community for advice when I stumbled upon an unexpected behavior during the wake-up phase. The support I received was invaluable, and it highlighted the importance of community-driven troubleshooting in the DIY electronics space.For anyone looking to implement TWT, I recommend starting with shorter intervals to understand the wake-up patterns and then gradually increasing them based on your application’s needs. It’s also worth noting that while TWT offers significant power savings, it’s best suited for applications with predictable traffic patterns.Overall, experimenting with TWT on the nRF7002 DK has been an enlightening experience, showcasing the potential of Wi-Fi 6 in creating more energy-efficient IoT solutions. I’m excited to explore more features and continue contributing to the community’s knowledge base.
