  • Thank everyone for their suggestions. I have just gotten back to trying this again (had some OT at work and other things going on).

    I am starting with a fresh install of everything (even my OS because when I tried to update Debian from stretch to buster, I broke it).

    The ESP32 board that I'm using are MELIFE 2 ESP-32S (ESP-WROOM-32 module with 4MB flash, no pSRAM).

    I've done a fresh flash of the firmware and I get the following right after flashing:

      sdkVersion: "v3.1.3-dirty",
      freeHeap: 35712, BLE: true, Wifi: true, minHeap: 33112 }
    ={ free: 2264, usage: 36, total: 2300, history: 13,
      gc: 0, gctime: 1.876 }
      VERSION: "2v04",
      GIT_COMMIT: "3956264e",
      BOARD: "ESP32",
      FLASH: 0, RAM: 524288,
      SERIAL: "3c71bff1-179c",
      CONSOLE: "Serial1",
      MODULES: "Flash,Storage,hea" ... "r,crypto,neopixel",
      EXPTR: 1073484860 }

    I then disabled bluetooth and get much more memory:

    ={ free: 4071, usage: 29, total: 4100, history: 0,
      gc: 0, gctime: 3.209 }

    Then I turned on WIFI using

    var ssid = 'YOUR_SSID';
    var password = 'YOUR_SSID_PASSWORD';
    var wifi = require('Wifi');
    wifi.connect(ssid, {password: password}, function() {
        console.log('Connected to Wifi.  IP address is:', wifi.getIP().ip);; // Next reboot will auto-connect

    My WIFI does not re-connect on it's own (if I say reboot my WIFI router). However, it does connect when I reboot the ESP32.

    I'll try some of the other suggestions and see what I get.
