Error with ESP32-C3-M1

[philipPerlick]

After connecting with the Phyphox-App, the ESP crashes with an error:
FreeRTOS: xTaskCreatePinnedToCore: Invalid core ID (1)

In my case the problem appeared in the startTask function of 'phyphoxBLE_ESP32.cpp':
xTaskCreatePinnedToCore(staticStartTask, "TaskTransfer",10000, NULL,1, &TaskTransfer, 1);

According to the documentation of FreeRTOS I could fix it, by replacing the above line with:
xTaskCreatePinnedToCore(staticStartTask, "TaskTransfer", 10000, NULL, 1, &TaskTransfer, tskNO_AFFINITY);

FreeRTOS docs: https://docs.espressif.com/projects/esp-idf/en/v4.3/esp32/api-reference/system/freertos.html

Code to reproduce:

#include <phyphoxBle.h>

void setup() {
   PhyphoxBLE::start();
}
void loop() {
   float voltage = analogRead(34)*3.3/4096.0;
   PhyphoxBLE::write(voltage);
   delay(50);
}

Thanks, for reporting this and for providing the solution with the problem. We do not have an ESP32-C3 at hand, but had a report of an issue that might be the same, so I let them test the fix and then I will do a small release with it.

Also I need to figure out why we pinned the process to a specific core in the first place to decide if doing so for the "normal" ESP32 is still preferable or if we just ported this behavior from another platform when implementing the ESP32 version of our library.

Finally got around to testing. Will release a new version with this fix later today. Thanks!

Just a status update: The Arduino library registry has not yet picked up the new release and I cannot even see any logs of it trying to do so. Could be because it is pointing at an old repo redirecting here, which is the first thing I will try to solve. So, just a quick note that while I made a release of this fix, it is not yet available from the Arduino IDE.
