Get height causing reboot

[SeraphimSerapis]

After successfully connecting to my desk (using a Linak DPG1M004-00) and WiFi, I ran getHeight to get my device's current height. This is what I got, followed by a rebooting ESP32.

Any clues what may cause this behavior?

Hey, thanks for giving my project a try! :)

First thing that comes to my mind is that you may have a different set of dependencies considering esp32-arduino-lib-builder and /builds/idf/crosstool-NG/ in paths of your sources - I don't have those.

Could you share some details regarding your local setup? What are you building on, and if you may be reusing some dependencies from other projects?

[SeraphimSerapis]

Thank you for the swift response. It's much appreciated!

I'm building on a MBP 16" running Big Sur 11.2.2. I recently received this as a new machine and this is one of the first few ESP projects I'm building, so I am not sure if any of the overhead you noticed may come from that.

My setup is VSCode into PlatformIO 5.0.4 and starting with a clean build from there.

I tried building https://github.com/j5lien/esphome-idasen-desk-controller and a few other EPSHome issues, but ran into similar issues on this platform. As the project's author states he took heavy inspiration from your project, I figured I reach out to you first.

I'm terribly new to building for ESPs/Arduino outside the ESPHome universe, so if there is anything you'd need me to run: I'm all ears! :)

Thanks again for your help!

[krzmaz]

It may be a BigSur thing, as I am on a MBP as well, just Catalina 10.15.7... (I haven't switched yet due to being afraid of platform problems 😅 )

For starters as you have previously played around with ESPhome things, I'd recommend removing as much of ESP related things as you are comfortable with, and letting platformio download and build all that's needed.

I've just checked out the repo to a new location, removed everything ESP related from ~/.platformio/platforms and ~/.platformio/packages and did a rebuild, and everything works...

Here is the log for you to compare: fresh_install.log

Make sure the platform and toolchain are properly installed and compare yours PLATFORM, HARDWARE and PACKAGES sections. Also check the versions of

|-- <ESP Async WebServer> 1.2.3
|   |-- <AsyncTCP> 1.1.1

because I recall that there were some problems with those libraries

As I cannot reproduce the problem, I most likely won't be able to help you a lot, but let me know if you have any new questions or findings! Good luck!

[krzmaz]

@SeraphimSerapis One additional thing I've noticed is that after reboot you get Couldn't connect to desk! which is odd as for me ESP is always able to reconnect after reboot if the desk is not connected to no other device. Are you sure that your BT connection is stable? When you manually reboot the ESP board does it reconnect?

[SeraphimSerapis]

I noticed that, too. It doesn't seem to keep the connection persistently, but I haven't figured out why. I noticed this across different ESP boards. Might be some weird controller thing. I'll reset tomorrow and will build from scratch as you suggested and will keep you posted.

Thanks again for being so helpful!

[krzmaz]

One thing you can also do if the fresh build doesn't help is to play with different debug log levels set here: https://github.com/TheRealMazur/LinakDeskEsp32Controller/blob/main/platformio.ini#L28

You can add , log2file to monitor filters in line 25 to have the serial output written to file, as there will be a lot of it 😉

Let me know how it goes, I want to make this software work with as many devices as possible! 😁

[SeraphimSerapis]

Thanks again for your help. I reset my desk, removed conflicting platformio versions and did some more housekeeping -- now the ESP32 reconnects to the desk but I still get a crash every time I run the get or move command.

My hunch is that my controller might not match the Ikea idasen commands and therefore doesn't seem to comply with whatever my poor ESP32 sends via BLE.

[krzmaz]

Hmm as all your backtraces point towards the AsyncWebServer stuff, I'd like to check if the connection works when invoked manually. Could you apply this diff and run the code? getHeightAfterConnect.txt

If it works you can add controller.moveToHeight with a value near to the current height, to see if that works as well.

I was planning to improve the controller to work in more async fashion anyway, so I might have more code for you to test later this week 😁

It seems like indeed the webserver seems to be causing the problems, not the actual code you use to control the desk.

[krzmaz]

Okay, that seems to narrow down the problem. I'm surprised that getting the height via http request doesn't work for you, since it takes below 200ms, which should be reasonable for the async server... BTW do you see a lot of fluctuation in the handling time of getting height? I see in your logs 174ms and 113ms. With my controller it is always within couple of ms around 120ms...

Another thing we should test is to check whether it is a general problem with the web server or a problem with the interaction between the web server and desk controller. Could you add this code:

        server.on("/heap", HTTP_GET, [](AsyncWebServerRequest *request){
          request->send(200, "text/plain", String(ESP.getFreeHeap()));
        });

above or below other calls to server.on in setup?

Doing curl 192.168.20.201/heap you should get the amount of free heap (for me it's around 24000).

Also, looking around the internet for possible root causes I've stumbled upon answers suggesting that the problems may be related with the hardware itself, especially we should look into the way your ESP is powered. When doing a lot of communication - both BT and WiFi, the ESP could experience voltage drops leading to weird behavior. Could you double check with different microUSB cables and different power sources (i.e. power bank instead of USB port)? Just to rule that one out 😛

Couldn't connect to desk!

Another crash when I try calling /heap after adding the server.on line.

I tried a hotspot to rule out firewall snafu. The difference in latency probably comes from: "Does Tim stand between the ESP32 and the desk or not".

[krzmaz]

Okay, from __cxa_allocate_exception I'm assuming that your ESP may be running out of heap memory, so let's check that by adding this code in loop():

    static unsigned long last = millis();
    if (millis() - last > 5000) {
        last = millis();
        Serial.printf("[MAIN] Free heap: %d bytes\n", ESP.getFreeHeap());
    }

If the values printed there will be around 20000 as in my case, please enable core debug logs as mentioned here: https://github.com/TheRealMazur/LinakDeskEsp32Controller/issues/7#issuecomment-794420088 and let's see if there are any useful information logged when you do curl 192.168.20.201/heap

[SeraphimSerapis]

It says [MAIN] Free heap: 124420 bytes.

I also changed platformio.ini to

build_flags = 
  ; -DCORE_DEBUG_LEVEL=5, log2file
  -std=gnu++17
  -Wall
  -Wextra

Where would I define the file to log to? Or is this a flag that automatically creates that log file?

[krzmaz]

Hmm, that's a interestingly high amount of free heap memory, what is the ESP board you are using?

To enable the logs, you need to change line 25 to: monitor_filters = esp32_exception_decoder, log2file and uncomment (remove the ;) from line 28:

[env:esp32dev]
platform = https://github.com/platformio/platform-espressif32.git#feature/idf-v4.0
platform_packages =
  ; use upstream Git version
  framework-arduino-esp32 @ https://github.com/espressif/arduino-esp32#idf-release/v4.2

board = esp32dev
framework = arduino
monitor_filters = esp32_exception_decoder, log2file
monitor_speed = 115200
build_flags = 
  -DCORE_DEBUG_LEVEL=5
  -std=gnu++17
  -Wall
  -Wextra
build_unflags = -std=gnu++11
upload_speed = 921600
board_build.partitions = no_ota.csv
; debug_tool = esp-prog
; upload_protocol = esp-prog
; debug_init_break = tbreak setup
lib_deps = 
  me-no-dev/ESP Async WebServer @ ^1.2.3

The logs will be saved to a file with a timestamp in the name whenever you open the serial port monitor

[krzmaz]

Regarding hardware - could you look if you get similar data in your upload logs?

The board I use is this one from Amazon (produced by AZDelivery - ESP-WROOM-32).

[SeraphimSerapis]

And here is the debug log you asked for: platformio-device-monitor-210311-113934.log

[krzmaz]

Okay, from the log, this is the line we could investigate, there seems to be a timeout in _poll function of AsyncTCP.cpp right before the reboot: [W][AsyncTCP.cpp:950] _poll(): rx timeout 4

One other thing is that your board seems to have more RAM that the default esp32dev I'm using. I've found info on a preconfigured setup for that manufacturer's board here: https://docs.platformio.org/en/latest/boards/espressif32/az-delivery-devkit-v4.html#board-espressif32-az-delivery-devkit-v4

Could you change the board value in platformio.ini as follows?

[env:esp32dev]
platform = https://github.com/platformio/platform-espressif32.git#feature/idf-v4.0
platform_packages =
  ; use upstream Git version
  framework-arduino-esp32 @ https://github.com/espressif/arduino-esp32#idf-release/v4.2

board = az-delivery-devkit-v4
framework = arduino

and test it?

[SeraphimSerapis]

Done! The result seems to match the previous behavior noticed: platformio-device-monitor-210311-125057.log

[krzmaz]

Hmmm yeah, but there is definitely something wird going on with the amount of free heap memory available to the MCU - grepping the previous log shows:

[MAIN] Free heap: 14748 bytes
[MAIN] Free heap: 14748 bytes
[MAIN] Free heap: 14748 bytes
[MAIN] Free heap: 13288 bytes
[MAIN] Free heap: 124208 bytes
[MAIN] Free heap: 124208 bytes
[MAIN] Free heap: 124208 bytes
[MAIN] Free heap: 124208 bytes
[MAIN] Free heap: 124208 bytes
[MAIN] Free heap: 124208 bytes

and for me it shows constantly values around 24000...

I see that your Amazon link is for 3 pieces - have you tested the code on multiple boards? My German is a bit rusty, but I saw a comment mentioning problems with connectivity on the board...

If you tested on multiple boards then it may be a problem with configuration - it may require special configuration based on https://github.com/platformio/platform-espressif32/blob/master/boards/az-delivery-devkit-v4.json ... I really don't want to be that guy to recommend this, but it may be quicker to just get boards from a different manufacturer 😶

[SeraphimSerapis]

I tried this on 2 out of 3 boards (1 is out of reach right now) and agree that I may have to buy a different board (or two) to see if they work better.

Thanks again for your help!

[SeraphimSerapis]

What I missed to say is: thank you for your helpfulness and the work you put into this project. It's very much appreciated! 🎉

[krzmaz]

Thanks, glad to read this 😊

Hope that new boards will work without problems!

[krzmaz]

@SeraphimSerapis Were you able to get the controller working with different ESP32 boards? I've just posted an update changing the BLE library, which saved about 100kB of heap in runtime, and reduced the program size removing the need of custom partitions. If you have the time to test it, I'd appreciate the feedback on the latest version :)

[SeraphimSerapis]

@TheRealMazur Thank you for checking! I ordered a different board (same manufacturer) but ran into the same issue. I also ordered some other boards from other manufacturers but am not sure when they'll be delivered. They might be stuck somewhere on the Suez Canal 😆

I'll test your code tomorrow and will keep you posted on how things go!

Starting Config Portal

[krzmaz]

I see that stacktrace is from the WebUI page, have you tried simple endpoints - /heap and /getHeightMm? I see that you were able to set some values in the ConfigPortal, so that means the webserver finally worked! I'm suspecting that your board has some weird configuration regarding RAM - the Amazon listing said 520KB which is more than my boards have (I'm testing on two different boards with 320KB of RAM each), but the symptoms suggest that there are still issues with memory... When BT stack gets initialized, the problems start to appear...

One last thing you could do right now is to again change the board in platformio.ini to
board = az-delivery-devkit-v4
but I think that your boards are something different, and not those v4 kind...

If you feel like it, you could also experiment with enabling SPIRAM, but without access to your boards I won't be able to help much with debugging... According to this: https://community.platformio.org/t/correct-settings-to-enable-external-ram-on-esp32/18607 https://docs.platformio.org/en/latest/platforms/espressif32.html#external-ram-psram it could help just to add

    -DBOARD_HAS_PSRAM
    -mfix-esp32-psram-cache-issue

to build_flags

[SeraphimSerapis]

It seems like this is what has been missing. No crashes for now! Thanks for being so dilligent!

I adjusted both the board as you suggested and added the two build_flags.

That's great news! 😁 I think it was the build flags, as changing the board hasn't helped last time. I thought that the board definitions had those PSRAM fixes included but apparently not. I'm closing the issue.

BTW Do you maybe have a alexa device and would want to test controlling the desk with voice commands? ;>

[SeraphimSerapis]

I fear I don't. Plenty of Google Assistant devices but no Alexa in my home :D

[krzmaz]

Sadly Google Home seems to be harder to integrate - AFAIK it uses only cloud solutions and not direct local communication to smart home devices... At least that's what I've found in the issues of the library I'm experimenting with: https://github.com/vintlabs/fauxmoESP/issues/124#issuecomment-761164849 That's a shame for people who use voice assistants other than Alexa, as I'm currently experimenting with controlling my desk with an Amazon Echo using fauxmoESP library and it's a very nice experience 😁

Anyway I'm glad that the project works for you and I hope you find it useful! 😊
