Can we have this allowed within programs please Peter ?. It would be MUCH easier moving from one known wifi to another then....

A man of few words, is Peter. :)

There will be good reasons why not though.

Getting the Webmite/Pico2-W to run reliably has been a nightmare - it's basically a c..p design. There is no chance I'm going to change anything on this port relating to anything to do with the wifi/web operations

Reminds me of an old friend talking to his 9 year-old daughter:

Friend: "So how's it going at school?"
Daughter: "Fine"
Friend: "Well can you expand upon that?"
Daughter: "Fiiiiiiiiiiiiiiiiiinnnnnnnnnnnnnnnnnne"

I have the same problem, and would be quite happy for the system to reboot as soon as it hits the option wifi line of code.

I have a solution for myself. Switch the console to a serial port on the webmite and put the user interface on a second Picomite which sends the option wifi command to the webmite through the serial port. This has the advantage of being able to display friendly messages while the webmite is rebooting.

This means the webmite can have really simple code that just handles the HTTP requests and the picomite drives the touch screen and handles the UI. It can also be used as a watchdog for the webmite. The hardware watchdog really doesn't work well on HTTP as the code can regularly take longer than the watchdog time limit. I think you could output a "." every second or so to show the processor is running and the picomite will send a "^C" and cpu restart if it gets no serial activity for 10s. You could use the software watchdog on the webmite, but the serial activity means the picomite can also display an online indication.

That looks like a good solution.
Below is what I have been using. It's adapted from the work of others here.
Sub MM.STARTUP
  Pause 200
  On error skip 6
  If MM.Info(ip address) = "0.0.0.0" Then    'test for WiFi link
    Print "WiFi not found";
    Pause 8000
    Print "...Rebooting now"
    CPU restart  'endless re-boot until WiFi found
  EndIf

  Local float TZ = 10, DS = 1    'Time Zone, Daylight Saving
  Local integer n = 0
  Do While Date$ = "01-01-2024" 'test internet connection, wait for date$ to update
   On error skip
    WEB NTP TZ+DS, "203.12.160.2" 'Second choice is 0.au.pool.ntp.org or 1.au.pool.ntp.org

   Inc n : Print n; " tries", DateTime$(now),
   Pause 2000
   If n=15 Then End Sub 'give up!
  Loop
  Print
  RUN 'start main program
End Sub

I agree but, to be Zen about it, it is what it is.

The webmite is easy to break but if you really want to try, this should work:
'
print "started"
END "option wifi "+chr$(34)+"myWiFi"+chr$(34)+","+chr$(34)+"myPWord"+chr$(34)


It causes a reboot with the new WiFi

Should really use
If n=15 Then Exit Sub 'give up!

Both execute the same code

I know - but it's wrong and if someone ever changes the parser or writes another it'll show up as a bug.

In this instance it doesn't matter if it fails with an error as it has failed to find the internet and the program is abandoned.

Thanks Jim,

I will give this a go before proceeding with my option. It basically does what I need and saves a second processor and serial port.
