Is WiFi communication reliable with M5StickC+2?

[ram00]

With a M5StickC+2, is WiFi communication possible and reliable?

It should be possible since the included ESP32-PICO-V3-02 chip has WiFi built-in.
However I read a few (old) posts where problems were reported with earlier models.

In addition, there is no external antenna or antenna connector, surely impacting the range covered.

Have you add success? Which programming language was used?
