Reboot after successful run

After run I'll get following information :

Hello @anttitai
A assume your compiling in Arduino IDE. Since it does not manage dependencies properly you might probably be using the master branch version of the ESP-FlexyStepper library.
The issue you describe is probably only occurring when you start moving the stepper motor, right?
If so, you should install ESP-FlexyStepper version 1.2 and not the last version from master branch.
The master branch is currently in a state that has issues with new features.
Please provide more details if the issue persists after installing ESP-FLexyStepper 1.2

In general I recommend using a proper IDE that can manage dependencies a bit better than Arduino IDE, I suggest taking a look into PlatformIO. It is free and takes only minutes to install and get ready to go and has way more features than Arduino IDE. But that is just a side note, once you update the Library version of ESP-FlexyStepper you should be able to run it also using the Arduino compiled code

closed since it has been confirmed working by @anttitai in the duplicate of this issue

The problem seams to be still present. As there is no version 1.2 available of the ESP-FLexyStepper I tried with the 1.3
Any recommondations?

please post your script with the main function / Setup function and which exact version of ESP-StepperMotor-Server you have installed.
Also please provide information about which hardware you are using (revision and memory).
The decoded backtrace would also help a lot to identify the exact position in the code.

ESP-FlexyStepper 1.2 is available here: https://github.com/pkerspe/ESP-FlexyStepper/releases/tag/v1.2

@lazyzero FYI I will work this weekend on a new release of both, ESP-FlexyStepper and ESP-StepperMotor-Server, to ease dependency management issues

Hi @pkerspe ,

I used the code from the readme.
`void setup()
{
Serial.begin(115200);
stepperMotorServer = new ESPStepperMotorServer(ESPServerRestApiEnabled | ESPServerWebserverEnabled | ESPServerSerialEnabled);
stepperMotorServer->setWifiCredentials(wifiName, wifiSecret);
stepperMotorServer->setWifiMode(ESPServerWifiModeClient); //start the server as a wifi client (DHCP client of an existing wifi network)
stepperMotorServer->start();
}

void loop()
{
}`

This are the importand infos from platformio:

`
PLATFORM: Espressif 32 1.12.2 > DOIT ESP32 DEVKIT V1
HARDWARE: ESP32 240MHz, 320KB RAM, 4MB Flash

  -- HTTPClient 1.2

  -- ESP-FlexyStepper 1.3`

I use the platfomio registry for fetching libraries. and If you look on https://platformio.org/lib/show/7427/ESP-FlexyStepper you will see that the version 1.2 is not listed there. It is 1.0, 1.1 and 1.3

I will wait for the weekend then ;-)

Hi Christan (@lazyzero),

I released a new version of ESP-FlexyStepper that fixes the kernel panic: https://github.com/pkerspe/ESP-FlexyStepper/releases/tag/v1.3.1

You can install it manually by downloading the zip file or you wait 1-2 days until it is indexed in the Platform IO Library manager (as soon as it shows up here, you can also install it via the platformIO UI: https://platformio.org/lib/show/7427/ESP-FlexyStepper)
