Recently, I’ve been diving into the world of BLE (Bluetooth Low Energy) advertising and have encountered some interesting challenges. I’m working on a project that involves using a nRF5340 module (Raytac MDBT53-1M) to send manufacturer data via normal advertisements. The goal is to replace an existing product that uses a Silicon BGM111 BLE module. However, I’ve noticed that the reception on the BGM111 side is quite poor when using the nRF5340. Often, the advertisements aren’t detected unless the devices are extremely close, around 2 meters. This is a significant drop in performance compared to the old setup, which could detect advertisements from over 50 meters away.
I’ve tried tweaking various parameters to improve the situation. For instance, I adjusted the advertisement intervals to see if that would help. I also played around with TxPower settings in my prj.conf file, enabling dynamic TxPower control and setting specific power levels. Despite these efforts, the results haven’t been as impressive as I hoped.
I’m curious if there are any additional parameters or configurations that could help optimize the BLE advertising to ensure better compatibility with the BGM111 receivers. Maybe there’s something related to channel selection or TxPower management that I haven’t considered yet. If anyone has experience with similar setups or knows of best practices for BLE advertising optimization, I’d love to hear your insights!
On a lighter note, I’ve also been experimenting with integrating multiple smart devices from different brands into a cohesive system. It’s been a learning experience figuring out how to get everything to work smoothly together. I’d be happy to share any tips or tricks I’ve discovered along the way, or to discuss any challenges others might be facing in their own setups.
Let’s keep the conversation going and help each other navigate the exciting (and sometimes tricky) world of BLE and smart home integration!
