new c6d7c896c examples/nimble_bleess: Add Environmental Sensing peripheral
c6d7c896c is described below
commit c6d7c896c2e0a9a34f2d432fbf9d90fdccd6e01a
Author: Jackson-gjh <[email protected]>
AuthorDate: Sat Nov 7 15:24:50 2026 +0800
examples/nimble_bleess: Add Environmental Sensing peripheral
Add a reusable NimBLE peripheral example for the standard Bluetooth
Environmental Sensing service. The example exposes readable and
notifiable Temperature and Humidity characteristics using their standard
0.01-unit encodings.
Generate slowly changing sample values so the example can be exercised
without sensor hardware, while keeping the GATT update function available
for integration with a real sensor.
The example was built and run on ESP32-C6. A Bleak client discovered the
service, read both characteristics, and received notifications from both.
