I’ve been diving into the world of smart home integration lately, and I must say, it’s been quite an adventure! 
I recently started working with the Nordic SDK, specifically using the nRF51822 chip, and I’ve been experimenting with LED controls. Initially, everything was running smoothly, but I stumbled upon an interesting issue when I tried swapping the LEDS_ON and LEDS_OFF methods in the examples. To my surprise, the LED_IS_ON function started returning positive values all the time, which completely threw off my LED flashing logic. It’s a bit puzzling, but I’m determined to figure it out! 
Meanwhile, I’ve also been exploring Zigbee integration with my smart home setup. I’ve got a mix of devices, including some Aqara window and door sensors, and I’m trying to get them to work seamlessly with my existing system. Pairing them initially was a breeze, but maintaining consistent communication has been a bit of a challenge. The LQI values are decent, but sometimes the sensors just don’t report their status reliably. I’ve heard that sometimes devices need to be paired directly with the coordinator, which is what I ended up doing, but it’s not the ideal setup I was hoping for. 
On another note, I’ve been keeping an eye on the latest updates from Qolsys IQ2. They mentioned a new panel release this month, and I’m curious if there’s a way to upgrade my existing IQ2 panel to the newer version. Also, the feature to answer the doorbell directly from the panel sounds super handy! I wonder if that’s included in the upcoming updates or if it’s exclusive to the new panel. Keeping my fingers crossed for more details! 
Lastly, I’ve been experimenting with BLE UART bridges for some custom projects. Running at 1 Mbps PHY with a 7.5 ms connection interval, I was expecting a higher throughput, but in practice, I’m only achieving around 0.13 Mbps. I’m curious if there’s a limit imposed by the BLE stack or if there’s a way to configure the packet count per interval in Zephyr to optimize this further. Any insights from the community would be super helpful! 
Overall, it’s been a mix of triumphs and tweaks, but I’m loving the journey of learning and improving my smart home setup. Here’s to many more exciting projects and discoveries!
