Downloading data from the integrated data logger.
Setup of data logger interval.
pip install sensirion-smartgadget
from sensirionbt import SmartGadget sensor = SmartGadget('CA:FE:12:34:56:78') print(sensor.get_values(init_static=True)) # 'init_static' is optional; it fetches following values immediately. print("Manufacturer:", sensor.manufacturer) print("Model:", sensor.model) print("Firmware:", sensor.firmware_version)
The device only allows one connection at a time. If the connection keeps failing, make sure you have disconnected other services, e.g. the smartphone app.
On a connection failure, transmission will be re-attempted, depending on the ‘retries’ argument or property. The default is to retry twice.
The first connection and value readings take a few seconds. The reason for this is that characteristics are discovered by UUID, then handles are cached and reused for subsequent calls.
