@teastain thanks but unfortunatly doesn't the Tab5 exist in 2.1.4 an simpler than the below can't the sketch be made:

#include <M5Unified.h>
#include <WiFi.h>
void setup() {
auto cfg = M5.config();
M5.begin(cfg); // ← hier wird intern der C6 hochgefahren
WiFi.begin(ssid, password);
}

I got my Tab5 - cool thing :-) but I I have an issue with WiFi.

Basically the C6 should work as a coprocessor connected with SIDO. This should allow using Wifi as normal with:

#include <WiFi.h>
WiFi.begin(ssid, password);

in the Arduino IDE. But instead a runtime error appears, and it restarts amd so on

        E (4372) H_SDIO_DRV: sdio card init failed

       FreeRTOS: FreeRTOS Task "sdio_read" should not return, Aborting now!

Does anyone know how to fix or have just a working example (there isn't any example around and even the P4 example with WiFi in the arduino IDE do not work)

Arduino IDE : 2.3.6; M5Stack Package 3.2.0 (all M5Stack lib on the latest state as well)
