 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

I can't be sure but I think that's one person's (somewhat workable) ideas but I wonder if the RPi foundation would say otherwise? Preferably with a better work-around! If lost, you'd hope that the connection could be re-made & the transfers resumed. John |

OPTION WIFI "pabu19", "mypw" PicoMite MMBasic Version 5.07.07a16 OPTION WIFI pabu19, ***************** OK, but how can i connect? |

@atmega After OPTION WIFI pabu19, ***************** and a restart you should be connected. The Pico shows the IP.* Regards Michael EDIT: * You should see the message "Connected 192.***.***.***". (See the first page of this thread.) You can then activate the telnet mode (e.g. Option Telnet Console ON) or/(and) install a website (HTML + .bas) on the Pico's flash drive (Xmodem).

Jim Please try the attached - it has lots of diagnostics enabled. PicoMiteWeb (2).zip Set to TELNET ONLY but open a USB connection then run your program from Telnet. You should see lots of diagnostics on the USB console. You can disconnect and then reconnect the Telnet console - that should now be benign If/when it hangs up then perhaps we can see what is happening. Thanks for your help |

I don't know if this have anything to do with the Wi-Fi reliability but I change the setting on my AP to 802.11 N only. Now my Pico W have been running open weather API ( update every 5 min ) for more than 12 hours. N/A |

Attached is a log file. log_170223.zip I have noticed that when my bas program stops during WEB TRANSMIT, the pico heartbeat stops but the logging continues, faithfully logging the Telnet keep alive bytes every 5 minutes. I also loaded micropython onto one of my picoWs and ran an example program. The python web server is no faster than the MMBasic one. Possibly slower to return a page than the MMBasic so I can't see much improvement likely. Hopefully, I am wrong) I will leave the system running over night with the web access turned of to see if it locks up on it's own. I also need to change MMEdit so capturing logs includes the timestamp. Always something to do... Jim VK7JH MMedit MMBasic Help |

Eureka I hope  Analysing the various outputs and tuning the diagnostic prints I think I've established that on occasion browsers will make a connection but not send any data. Up until now the firmware only closes the connection when MMbasic responds to a request. I've now put a timer on each connection. The timer is reset whenever activity takes place on the connection but if there is no activity for 5 seconds I now close the connection. Currently I have 4 different browsers running a total of 7 copies of Jim's program with the addition of the tiger picture and it has been running for 20 minutes. Previously this sort of load would crash it pretty quickly Keep you fingers crossed. If I make the 2 hour mark I'll post an update |

V5.07.07a17 PicoMiteWebV5.07.07a17.zip If TCP server mode is set on your Pico then after installing this please execute the command OPTION TCP SERVER 80 [, timeout] BEFORE DOING ANYTHING ELSE This is needed to set the timer used to close stuck connections. The time is in milliseconds and defaults to 5000 Otherwise you should not see any differences between this and a17 but there is a major re-write of the TCP server code under the covers There are three conditions that are now handled 1. a client connects but does not send a request 2. a client connects and makes a request while you are running a program but you don't respond within the timeout period 3. a client connects and makes a request while you are at the command prompt The server now acts as follows: 1. the connection will timeout based on the timer set in OPTION TCP SERVER and be closed completely transparently 2. This causes an error condition - you will get the Basic error "Error: No response to request from connection no n" 3. the server will automatically send a 404 code (page not found) I have run this with a number of browsers updating every 10 seconds and it seems stable. You can of course overload the ability of Basic to respond to the incoming requests in which case you will see an error but hopefully this is more robust than before.

Thanks Peter, also for the detailed explanation. I started a long term test with the a16 yesterday. Only USB console, the small web sample program, and only firefox browser from my PC, laptop, and mobile. My network is running streaming, sip telephony, and 3 kids :-) I once recorded the different access times from the PC. Test of a string: mystring is 16-02-2023 18:39:29 Test of a string: mystring is 16-02-2023 19:00:23 Test of a string: mystring is 16-02-2023 21:03:06 Test of a string: mystring is 16-02-2023 21:52:46 Test of a string: mystring is 17-02-2023 07:16:04 Test of a string: mystring is 17-02-2023 08:27:52 Test of a string: mystring is 17-02-2023 16:11:26 Test of a string: mystring is 17-02-2023 16:16:03 Test of a string: mystring is 17-02-2023 16:37:06 That's almost 24h of stable running. Almost funny, just now as I am writing these lines the error message appears in the console: ...

Just tried and .... 1) You get a syntax error without the word "PORT" 2) The timeout does not show with the OPTION List Thanks, Hans ....  |

Typo in my post - sorry Will fix but like all options it will only show if not default (5000) PS I'm probably going to change this anyway to allow 3 ports to be used Telnet, HTTP, and other Edited 2023-02-18 03:15 by matherp |

MQTT would be great for IOT devices Became a de facto standard in home automation/control Tasmota and many proprietary actors/sensors support it They could then act as I/O to the WEBmite |

After flashing a17 and running "OPTION TCP SERVER PORT 80, 6000", when I run the program I've been testing, after I enter "192.168.1.224" in the browser window, I get: Error: Invalid address - resetting PicoMiteWeb MMBasic Version 5.07.07a17 Copyright 2011-2023 Geoff Graham Copyright 2016-2023 Peter Mather Connecting to WiFi...

V5.07.07b18 PicoMiteWebV5.07.07a18.zip Fixes the display of the timeout + big speed improvement in displaying web pages and small images To ensure you have a clean start this will delete all options but not the flash disk lizby Clearly I don't get that. If you see that sort of issue use clean_flash and start from scratch. If that doesn't work I would need much more information on the sequence that created the issue. |

WOW, incredible the speed increase! A small glitch, when entering: OPTION TELNET CONSOLE ON picomite stopped working. Restart and entered more OPTIONs - running! > option list PicoMite MMBasic version 5.07.07a18 OPTION COLORCODE ON OPTION WIFI xxx, ***************** OPTION TCP SERVER PORT 80 OPTION TELNET CONSOLE ON > |
