SmartConfig makes the ESP crash when receiving the WiFi informations for connection #3711

christophepersoz · 2020-02-04T09:55:01Z

Hello,

Description:

I'm trying to make smartConfig running but I just got the board crash when the SSID/pass are provided to the board.

I tried the sketch post by @mickeypop about SmartConfig #1100 (comment), as well as the one provided as example by Espressif (example/WiFi/WiFiSmartConfig/WiFiSmartConfig.ino). My board configuration is based on ESP32 v1.0.4, Arduino IDE 1.8.10 and the latest version available of Arduino-esp32 library - all is running on macOS Mojave 10.14.6.
The location of the library is in sketches folder/hardware/espressif/esp32. To be sure of this I deleted it and reinstalled it by following the procedure indicated here: Installation instructions for Mac OS

Hardware:

Board: ESP32 Wemos Lolin 32 and ESPDuino 32
Core Installation version: 1.0.4
IDE name: Arduino IDE? 1.8.10
Flash Frequency: 80Mhz
PSRAM enabled: yes
Upload Speed: 115200
Computer OS: Mac OSX 10.14.6

Sketch

#include "WiFi.h"

void setup() {
  Serial.begin(115200);

  //Init WiFi as Station, start SmartConfig
  WiFi.mode(WIFI_AP_STA);
  WiFi.beginSmartConfig();

  //Wait for SmartConfig packet from mobile
  Serial.println("Waiting for SmartConfig.");
  while (!WiFi.smartConfigDone()) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("SmartConfig received.");

  //Wait for WiFi to connect to AP
  Serial.println("Waiting for WiFi");
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("WiFi Connected.");

  Serial.print("IP Address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  // put your main code here, to run repeatedly:

}

I check that my WiFi router is well configured in 2.4GHz as required by Espressif phone app to send the datas over the network to the ESP. I use ESPtouch app on iPhone to send the SSID/Pass to the ESP32 board.

I tried all of this on 3 different ESP board, 2 WEMOS Lolin EPS-32 and one EPS-DUINO32.

The sketch compile is OK, as the upload, but the connection does not occurs and makes the board crash.
I tried different method on WiFi.mode(); but neither WIFI_AP_STA or WIFI_STA seems changing anything.

Does anybody have encounter this, as I'm pretty sure that smartconfig should work as well as the code provided by @mickeypop.

Debug Messages:

For the moment I can't get the Debug Level on those boards. But I'm working to find a better debug trace than the Serial.

Here the traces I'm getting on serial output for the code provided by @mickeypop,

It is not the same error, but both seems related to wifi ipc
Does that ring a bell to anybody?

Expectation

Running smartConfig on ESP32 board and got the connection when sending SSID/Pass datas from ESPtouch app.

Thanks

mickeypop · 2020-02-04T17:46:42Z

did yo ever get EspExceptionDecoder working?

like sketches, the file name and the folder name have to be the same or it will not be indexed

ie;
YourSketchFolder/tools/EspExceptionDecoder/ and put EspExceptionDecoder.jar in that folder for arduino to index it and put it in the menu

christophepersoz · 2020-02-04T20:54:14Z

Yes, I finally got it running! I hope it could help.

mickeypop · 2020-02-04T22:29:58Z

thanks for the decoded post

it is showing a corrupted heap. I saw this one before.
when nodeMCU-32s first came out i saw this and switching to ESP32 Dev Module as the target board fixed it for me.

this is in the boards.txt option under ESP32 Dev Module
esp32.menu.PSRAM.enabled.build.defines=-DBOARD_HAS_PSRAM -mfix-esp32-psram-cache-issue
WeMos does not have this param

it is the only board definition with the -mfix-esp32-psram-cache-issue param

i believe this may help

UPDATE; i just noticed you are using the 240MHz so you can add the param to your boards.txt but just remember it changed anytime you update for the git repository

christophepersoz · 2020-02-05T00:26:14Z

Thanks for the tips @mickeypop.

I dig a bit in the board.txt and add few options on the Wemos Lolin 32 to experiments; the changes I made are based on the ESP32 Dev Module as suggested.

Board.txt changes under the lolin32 definition

lolin32.menu.PSRAM.disabled=Disabled
lolin32.menu.PSRAM.disabled.build.defines=
lolin32.menu.PSRAM.enabled=Enabled
lolin32.menu.PSRAM.enabled.build.defines=-DBOARD_HAS_PSRAM -mfix-esp32-psram-cache-issue

lolin32.menu.DebugLevel.none=None
lolin32.menu.DebugLevel.none.build.code_debug=0
lolin32.menu.DebugLevel.error=Error
lolin32.menu.DebugLevel.error.build.code_debug=1
lolin32.menu.DebugLevel.warn=Warn
lolin32.menu.DebugLevel.warn.build.code_debug=2
lolin32.menu.DebugLevel.info=Info
lolin32.menu.DebugLevel.info.build.code_debug=3
lolin32.menu.DebugLevel.debug=Debug
lolin32.menu.DebugLevel.debug.build.code_debug=4
lolin32.menu.DebugLevel.verbose=Verbose
lolin32.menu.DebugLevel.verbose.build.code_debug=5

Then I compiled the WiFiSmartConfig.ino sketch, and submit the SSID/Pass to the ESP32. It crash again, with and without PSRAM, that doesn't change anything. It just helped me to have a better understanding as I could activate the Debug Level to "Debug". The problem remains with the 3 boards I'm running the SmartConfig sketch.

atanisoft · 2020-02-05T00:33:49Z

Based on the output, that board does not likely have PSRAM so the additional parameters for that are not necessary.

christophepersoz · 2020-02-05T00:37:47Z

Indeed, the PSRAM can't be initialised on boot as WROOM modules does not have PSRAM

lbernstone · 2020-02-05T01:46:37Z

How do you have the app configured on your phone? Perhaps the ssid or password has an invalid character in it?

christophepersoz · 2020-02-05T14:27:27Z

@lbernstone, the ESPtouch app as well as ioT Smartconfig app does not have any setup, you just enter your SSID and Password and then you submit it. But, your idea of checking the password of the SSID was a good lead. I changed the password which was containing an _
I removed it, and check, and the connection was successfully established with the 2 sketches. So I roll back to the old password with the _ char to see if that was the cause, and the connection occurs correctly. Maybe there was something wrong on the router and changing the password make it right and working normally. Thanks a lot, I haven't thought to this a second!

@mickeypop, once received for the first time the SSID and Pass, unplug and restart the board make it connect to the network normally. Perfect! Thanks for sharing your code! 😉

I have the same problem. Unfortunately it didn't fix when i changed the ssid name and password of my router. Always stuck in ......... session

christophepersoz · 2020-02-18T13:24:33Z

@kemaldede, Have you checked that your router isn’t set in 5GHz mode? SmartConfig, and maybe ESP isn’t working in 5GHz WiFi mode.

atanisoft · 2020-02-18T13:30:33Z

ESP32 only supports 2.4Ghz WiFi bands.

kemaldede · 2020-02-18T13:32:01Z

thank you for fast response. I checked my router. The smart config example with esp-idf example code is working,but not with arduino

mickeypop · 2021-02-17T21:18:29Z

@kundannakalank
without any code or circuit, it looks like you are using the mutex handler and causing a timing out.
This usually caused by setting a lock, calling a function, forgetting to release the lock and calling something that needed the lock freed to use it.

this state tracking is especially needed if you are using both cores and using a shared resource like I2C, SPI etc...

i like to use mutex when working with multiple I2C devices.
ie; in every case, with mutex when you set a lock you need to release the lock when done for other functions to access the buss or it will timeout and call the panic.c lib to escape.
Simply using a global bool var to keep the cores from bumping into each other is a good start

the panic.c is a kernel timeout.
Somewhere your code is likely tying up a resource needed elsewhere.

can you post your code?
