What's Changed
Adaptive scanning
This release brings a very interesting feature for Bluetooth Low Energy scanning.
You may have already asked yourself, what should I set for the interval between my scans? Do I use passive or active scanning? Or how do these parameters impact the battery life of my sensors?
To remove these questions, @DigiH and I have integrated an innovative function - Adaptive scanning
Adaptive scanning will decide automatically following your devices if you need to use passive/active/continuous scanning.
For example, a door or a PIR sensor will require continuous scanning, so if detected, the gateway will reduce its time between scans to the minimum. Or your devices may also require active scanning to retrieve data. The gateway will trigger active scans at regular intervals in this case.
Behind the scenes, a big work on device categorization and analysis has been done in Theengs Decoder to enable this feature.
Why are we doing this?
Increase your sensors' battery life, decrease network traffic, and reduce gateway power consumption.
See below in Home Assistant how the interval is automatically adapted after the detection of a PIR sensor nearby.
This new feature is activated by default, you can deactivate it, and the gateway will go directly into continuous active scanning.
Consequently, the esp32ble-dev-cont environment has been merged into esp32ble-dev, and the "Active scan" command has been removed. You can remove the topic from your broker to delete it from the controller.
Theengs Plug
Also, this release brings support for the second RGB Led of the Theengs Plug alongside the capability to reset at the start. I encourage Theengs Plug users to update following this guide.
