4-Wire 54138 Watchdog timer reboot causing E13

[DeanozUK]

Describe the bug After install board seems to be stable with no issues until I select 4wire 54138 on CIO and DSP and reboot. While the board is idle (not even connected to pump) it will periodically reboot and when checking reason it says watchdog

To Reproduce Steps to reproduce the behavior:

1. After install goto hardware config and select 54138 for CIO and DSP and also select v2b
2. Reboot ESP and setup constant ping to device
3. Goto web page home page (maybe change temp)
4. page might drop out. I left it idle for sometime while on monitor via usb and I will post the log

Expected behavior Expect the unit to be stable when idle and when connected to unit

Screenshots ESP WDT Error.txt

Hardware (please complete the following information):

• Pump model, 54138
• 4 wire
• PCB type v2b
• Level shifter type, Red one

Software (please complete the following information):

• Firmware: 2024-06-17-1334

Additional context When its connected to the pump after startup I will just leave it without touching any buttons. only load the web page and after short amount of time it will E13. Also tried 2 other ESPs and the beta version to no effect.

Below is the result from USB Monitor.

Writing cmdq.json (I was changing temp on web page) Done! Writing cmdq.json Done! Writing cmdq.json Done! Writing cmdq.json Done! Writing cmdq.json Done! Writing cmdq.json Done!

[visualapproach]

Ok. I'll see if I can do anything about it

[DeanozUK]

Just a note on seeing deanzzzzz reply, I just remoted in on my router I forced a disconnect from wifi for the ESP and blocked it from reconnecting for 1min then unblocked it and it reconnected fine. Checked esp and no WD reboot. It just reconnected with no issues.

[visualapproach]

Yes, @deanZZZZZ just to rule out some things, does it make a difference if you make a clean build (platformio command) and also restart you router?

[visualapproach]

I'll process this post later. Had to prioritize the WDT issue. Thanks

Not a problem, would you rather I create a feature request to keep it separate from this issue?

@DeanozUK You should be able to just switch to model NO54173. It has the features you describe and should work.

[deanZZZZZ]

Yes, @deanZZZZZ just to rule out some things, does it make a difference if you make a clean build (platformio command) and also restart you router?

now I tried full clean disconnected the wifi 3x and it works fine :) ... I'll let you know how it goes ... with only pump runing power show 1,900 W all off show 950 W

[visualapproach]

@deanZZZZZ ok. In development branch you could turn on logging to file by editing platformio.ini and upload:

    ; -DBWC_DEBUGGING=BWC_DEBUG_OUTPUT_OFF
    ; -DBWC_DEBUGGING=BWC_DEBUG_OUTPUT_SERIAL
    -DBWC_DEBUGGING=BWC_DEBUG_OUTPUT_FILE

This will print the debug text to file and in the long run fill up the flash memory but it should be fine to run until you get a sw wdt. It is not completely finished yet but maybe you can see what is happening before the reset.

Or wait until I have more time to look at it.

[DeanozUK]

Ive had some sw wdt resets too now, not sure why all of a sudden.

{"BOOTINFO":"Software/System restart 2024-07-09 22:04:08"} {"BOOTINFO":"Software Watchdog 2024-07-11 18:24:17"} {"BOOTINFO":"Software/System restart 2024-07-11 21:17:06"} {"BOOTINFO":"Software Watchdog 2024-07-12 07:53:19"} {"BOOTINFO":"Software Watchdog 2024-07-13 15:58:23"} {"BOOTINFO":"Power On 2024-07-13 17:22:30"} {"BOOTINFO":"Software Watchdog 2024-07-13 19:55:56"}

I will looking into it tomoz when I get time.

Note: I tried the 54173 options and they do work better on web gui but I noticed that the buttons just beeped when pressed on pump and didn't do anythg. Ive switched back to 54138 again now.

@DeanozUK that is very strange! The only difference is that 173 allows more states, like air and jets on at the same time. Did you swap on both the DSP and CIO setting?

[visualapproach]

@deanZZZZZ @DeanozUK I have uploaded a new version to development branch. See if it helps with the resets. I frequently give back CPU to the OS, which would in theory help, if the problem is that user code takes too long. Unless I see the crash message it's really difficult to know exactly which part of the code is taking too much time. But if it works it works. There is also a potential fix to a "restore states" bug, for your info.

[deanZZZZZ]

Survived the night without restarting :)

[DeanozUK]

HI VA,

I've updated to the latest dev and can confirm it has been stable for 24hrs now. Damn its fast on boot now, If I restart the esp from browser its back up before the E13 timeout message which is really nice, well done.

The only SW WD I have encountered was when the unit had first booted (within 30secs) that I repeatedly press temp up (from default 20) to get to 37 and it WD reset on me. I have unfortunately been unable to reliably recreate this but will do some more testing. Note, I'm using the alt temp adjust display method instead of sliders.

`Note: I tried the 54173 options and they do work better on web gui but I noticed that the buttons just beeped when pressed on pump and didn't do anythg. Ive switched back to 54138 again now.

Please ignore this as it did same on 54138. I've since changed the board over to another and its fine on both so must have been a loose wire or config my end.

Super happy to hear that it works good (enough) now! Thanks for testing and reporting! I believe the fastest startup is with static ip. Remember to enter a DNS as well or the NTP won't find the time. Ask me how I know 😀

haha, I wont, I've been there myself. When I said it was fast....it was on dhcp too 😀 soooo will be even faster on static. Nice work!

I always put in a NTP server, but is there a default fall-back or it is a must?

The pings look so much better now, much more stable even clicking around on web page.

These addresses will be used your choice, if any else pool.ntp.org else time.nist.gov

Thanks for your feedback. I also feel the web UI on all models is much more responsive now, thanks to fixing your issue.

Hi VA, Its been 2 weeks and not a single crash/reboot or E13 error. you've cracked it. I've not updated it anymore since but 14days uptime is a win from me.

I did however get 1 issue where beeping from the DSP which displayed a flashing 'En8' its an odd 1 as I've seen this in the past with the old firmware when I was getting loads of connection issues and I remember 1 other user on a post here reported once. Its an odd one as its not documented as a error code and its not 'End' either. For now thou its not an issue as its been perfect other than this. Well done!

hmm... but for me it worked for two days without a problem, then SW 4x a day... and again 1 day ok... and similar
