      Using Arduino 1.8.12 , Library: M5StickC 0.2.0

      My M5Sticks run anywhere from 2days to 3 weeks and then crash.
      The crash typically happens right after some WiFi networking call.
      For example:
      crash after: http.begin(g_wClient , g_cHttpCmd);
      or crash after : iRSSI = WiFi.RSSI();

      After the crash, the M5 Stick C does not automatically reboot , which I believe it should

      Attached is the debug output:

          In this situation, we haven't met. our all firmware is used 240MHz default. maybe you could check it does related to your program.
