Back to Pico Wifi Analyzer Phase 1

If you have loaded the Python code in to Thonny and run it, then your Wifi Analyzer should be running, and look a little like what we have below:


There are some lines of text on the screen, and they are:

• Wifi Analyzer - Just a title, you can change this in the code, in fact you can change any of the text.
• Last: This was the time that the last scan occured.

• Linksys - This is my Linksys router, change the line in the software for your router
• Draytek- This is my Draytek router, change the line in the software for your router

• Linksys: 111 - Three scans have occurred, all successfuly. We show the result of the last 5 scans.
• Draytek: 1×1 - Here there were three scans, but one failed.

• Status - Either says 'Done' or 'Scanning' if a scan is in progress
• Next: 1m - Time until next automatic scan.

There are two buttons above the Pico:

• The button on the right is a 'Manual Scan' button - Press this to invoke and immediate scan. This does not interrupt the scheduled 15 minute scan
• The Left hand button is a reset, in case the Pico becomes unresponsive.

There is a Green LED on the left of the Pico:

• A solid Green means everything is good (from the Analyzers perspective)
• A flashing LED means that one or all of the SSIDs has failed. On the next test, if all SSIDs pass, light will go back to solid green.
