WiFi test failed or currently busy

This can be caused by a number of factors: 

1. Your sensor is currently connected or trying to connect to WiFi to upload files or perform OTA update.
   1. Go to the Sensor Status screen and check if it is Connecting, Connected, or in OTA Checking. If the WiFi is already configured properly, you can monitor the progress in the Sensor Status screen.
   2. If the sensor is trying and failing to connect to WiFi, this process will time out after 3 retries of a fresh startup or 100 retries when returning to the upload radius. A fresh start will accelerate the process.
2. Your sensor just booted and is in the process of configuring. Please wait 30 sec – 1 min and try again.
