      This applies as well if you use the M5Stack pkg? - is there a "how to" somewere for this?

        Hello @smily77

        no, AFAIK there is no specific 'how to' for M5Tab5 - only the generic about how to build your own Arduino library using Arduino library builder or how to use Arduino as ESP-IDF component. See links above.

        Thanks

          There seams to be an additional Issue the Tab5 uses SDIO2 - The correct GPIO's only don't work

            I believe SDIO2 is used so the communication between ESP32P4 (master) and ESP32C6 (slave) can be exclusive, e.g. not shared with other slaves.

              Hi there,

              are there any (better) news about using Wifi within the Arduino environment?

              kind regards
              Jörg

                Hi guys

                corresponding github issue for reference.

                It seems there isn't an easier way just (yet) than using Espressif Library Builder.

                Thanks

                  It was mentioned that in the next ESP-Arduino package 3.3.0 the issue with the connection will be solved by this possibility:

                  WiFi.setPins(clk, cmd, d0, d1, d2, d3, rst);
                  WiFi.begin(ssid, pass);

                  This sounds promising. However the Tab 5 doc's lists the Pins for clk, cmd, d0, d1, d2, d3 but not for the reset pin (rst). Does somebody know how the reset of the C6 is wired to the P4 in the Tab 5?

                    according to the schematic GPIO15 is used as reset pin (SOC_EXTRF_RST).

                    Thanks

                      @smily77 Did you manage to get the SD card reader to work?

                          I managed to get the SD card reader to work.

                          The WiFi module (ESP32-C6) uses an independent set of dedicated pins (SDIO2_D0 to SDIO2_CK), thus avoiding any physical interface overlap and conflicts.
