the sensor will still blink blue. Multiple unplugs might be needed for the sensor to complete the
upgrading. If it still keeps flashing blue after several unplugs, please perform a factory reset from the
App or manually perform the factory reset (see Sec. 4.2.17).
Sometimes if the WiFi signal is too weak, the sensor could go offline and blink white after restarting. In
this case, please set up the WiFi again from the App, and the download and upgrade will then continue
automatically and the sensor will still blink blue.
For Cypress sensor, make sure the sensor's power supply is not interrupted when the sensor is blinking
purple during upgrading, otherwise the sensor might fail to start up and has to be returned for repair
due to update failure.
