      The page for PoESP32 (SKU:U138 / https://docs.m5stack.com/en/unit/poesp32 ) clearly states

      ESP32-WROOM-32U 240MHz dual core, 600 DMIPS, 520KB SRAM (without integrated 3D antenna, does not support WiFi wireless function)

      But the ESP-AT firmware that ships with the device is configured to host an AP by default, and the device ships without an antenna or dummy terminator - is this safe for the ESP32-WROON-32U? I found no mention of this in the datasheet other than Espressif stating

      external antenna connector (which needs to be
      connected to an external antenna)

      without any reference to weather that is a requirement for function or safe operation, but most other RF devices have warnings about operating the radio without antenna or terminator/dummy load on the output to prevent damage.

      +CWMODE:2
      
      OK
      

      CWMODE:2 means the unit is in SoftAP mode by default, and it is confirmed by the prescense of the ESP_241B91 wifi network it creates.

      Is this the intended operation?
