 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. |

Hi All Just when I thought I have it all sussed, this happens after probably 30 minutes or less every time. At first I thought MMCC was responsible, but then connected the two Rpi's without using a terminal on the Pico and the same thing happened. It feels like a timeout, but the --help for mosquitto does not mention an adjustable life. Cutting snippets from the program shows the following sequence. If MM.INFO(WIFI STATUS) = 1 Then 'Keep coming back here till we succeed IP$ = MM.INFO(IP ADDRESS) 'Get my IP address Print "0";";"; 'This proves the hanging point, but not the TCP EndIf 'disconnect. WEB MQTT Connect "192.168.0.101", 1883,"Rpi-Hotspot","********",WebInt WEB MQTT subscribe "AmpHr" WEB MQTT subscribe "Control" Print "Comm's Initiated" '------------------------------------- Tyd$ = Time$ Print Tyd$ WEB MQTT PUBLISH "AmpHr",Tyd$ , 0 ,1 StartTime2 = mSec :Delay2 = 0 Print "Time sent ";Tyd$ Pause 15000 '-------------------------------------- WEB MQTT PUBLISH "AmpHr",IP$,0,1 Print "IP Sent ";IP$ The Pico sends a message on 30 sec interval and the Zero checks for Messages every 20 sec's. When it happens, it could take a couple of times of powering down, before it works and executes the first of the code above.Note I only power the Pico down, the Zero is still happily trying to get messages. Once it does, then works well for 30 min(will confirm) and then TCP error ? Will to put a delay on the Pico startup, giving the Wifi a chance to connect, but the TCP disconnect is a mystery. The mosquitto log shows quite a few of the following: Client auto_******long number******disconnect. But there are many of them whilst the Pico is still working, I have system options: OPTION WIFI SSID$, Passwd$ FLASH SAVE 1 OPTION AUTORUN 1 Does anyone know of a timeout that needs setting ? Regards Hervey Bay Qld. |

Hi all There is one problem wit MMCC though. After 61 lines the screen stops scrolling and showing the last transmission. Because I am sending an incrementing number, I know that at the moment I am receiving line 160 on the Rpi Zero and is still working ok. Edit: And I cant Ctrl-C out of the program.If I disconnect and then try to re-connect I get ttyACM0 Failed. Edited 2023-11-21 17:45 by Dinosaur Regards Hervey Bay Qld. |

What version are you using? There was a memory leak in MQTT which was fixed during V5.07.08 development |

Hi All Using WebmiteV5.07.08RC19 It is worth noting that if you Dis-connect and re-connect the screen will keeps scrolling down beyond the 61 lines. Regards Hervey Bay Qld. |

Hi All Need to ask a silly question. Does MMBasic clear all variables at the start of the program. Was chasing a weird problem and that didn't solve itself until I cleared the variable concerned at the start of the program ?? Regards Hervey Bay Qld. |

It should do when you use RUN (And NEW clears the program as well.) John |

Exactly, however you can be extra certain if you make the first line of the program:- CLEAR . |

Hi All The problem mainly happened during stopping and re-starting the program. But CLEAR is the best solution to guarantee. I guess I am spoiled by FreeBasic. Still having problems with Headless bootup and connecting succesfully. It takes twice ?? Edited 2023-11-22 09:31 by Dinosaur Regards Hervey Bay Qld. |

You aren't connecting to a Fritzbox by any chance. My Fritz needs two attempts but my other access-points are first time every time. Solution is to check the link and force a reboot if needed. Jim VK7JH MMedit MMBasic Help |

Hi All Don't know any Fritz , no.  Rpi-Pico connected to Rpi-Zero W by Wifi only. The same problem exists if I connect the Pico to the desktop by usb using MMCC. MMCC connects immediately but when I run it fails & have to reboot the Pico. It has to be rock solid reliable boot, otherwise it goes into the bin. After all there is only one other device on the network. (the Zero) I have tried to connect other devices to the hot-spot and they connect at once. Currently I am rebooting (Delay driven) but the complication is that the Rpi-Pico boots much quicker then the Rpi-Zero, so my web checking has to be perfect. But I will find the solution. Regards Hervey Bay Qld. |

Hi All How do I completely erase everything on the Pico. I have used "Flash Erase All" and followed up with "Flash List" to see that the flash locations are all available. (which they are) I have re-written the image file. But still Autorun is ON and it runs my program. Going to Edit shows it is there, BUT WHERE ? I am trying to test the comms with a blank Rpi-Pico to prove the connection issue. Without scouring through every page of the doc's, checking the Program and Data Storage does not shed light on this. RUN "A:/MyProgram.bas" pops aan error, so I guess it's not there either. ??? Regards Hervey Bay Qld. |

If you really want to take it back to factory fresh re-flash with CLEAR_FLASH.UF2 There will be nothing left at all. It is in some of the firmware download zips. |

Hi All Thanks guys. I have two Pico's and one has nothing loaded and behaves differently with connect/disconnect. So, need to confirm when both are clear, they are the same. Then proceed step by step from there. Regards Hervey Bay Qld. |

Connected 192.168.0.191 > SUCCESS I have done this many times and ALWAYS takes two goes. Using "cpu restart" or unplugging makes no difference. In order to work out if this is a Pico or MMBasic problem, I would have liked to get an .uf2 image in one of the other languages to see if the problem repeats. However, no amount of browsing has given me any luck and I don't want to start playing with a new language. Unless someone reading this has something I can use. So now I will test if it is just as repeatable from within my program. Regards Hervey Bay Qld. |

What router are you using - I bet I can guess - Fritzbox? |
||||
| Dinosaur Guru Joined: 12/08/2011 Location: AustraliaPosts: 311 |
Hi All As I said to Tassie Jim, I don't know any Fritz.  However, NO ROUTER. This is a hotspot connection created on the Rpi-Zero W and the Rpi-Pico is the only client. Regards Hervey Bay Qld. |

| matherp Guru Joined: 11/12/2012 Location: United KingdomPosts: 9122 |
Its probably a timing issue. The Pi-zero is too slow to respond until the required code has been read from the sdcard |

| TassyJim Guru Joined: 07/08/2011 Location: AustraliaPosts: 6099 |
Just put if not connected CPU RESTART endif in your program. Together with AUTORUN and the usual watchdog timers and you will have the reliability you are after. Jim. VK7JH MMedit MMBasic Help |

Hi All I think I have sussed the problem Using MM.INFO(IP ADDRESS) in any checking of connection is hampered by the fact that disconnecting,by quitting the program or powering off the Rpi-Zero that supplies the hotspot does NOT clear it "0.0.0.0". So this code that I use: If InStr(MM.INFO(IP ADDRESS),"192.168.0.") > 0 Then only works if I power down the Pico.Print MM.INFO(IP Address) CommFlag = 1 Exit Do Else Print MM.INFO(IP Address) If StepNbr = 0 Then 'Only at original power up IF mSec - StartTime > 100 THEN 'if not there by 100mSec Print "CPU Restarting" 'even 15 sec's doesn't help CPU RESTART 'so may as well restart. EndIf EndIf Exit Sub EndIf I have a CLEAR statement at the start of the program, but that does not seem to clear it. Have also tried:MM.INFO(IP ADDRESS) = "0.0.0.0" which does not create an error but doesn't clear the IP address. Am I the only one with this problem, or am i missing something.? Edit: As Jim suggested "RESET" works , but then I have to set all the options again. I guess there is no batching of these commands before starting the Program. Edit again: Even if I could POKE 1 byte to the IP address location in memory, that would be enough for my code to fail the test. Edited 2023-11-24 15:23 by Dinosaur Regards Hervey Bay Qld. |
