  Tried to reduce JSVARs by changing the 40,000 value in ...../targets/esp32/main.c (Did not find any other place to do it)

  static void espruinoTask(void *data) {
    int heapVars;
    PWMInit();
    RMTInit();
    SPIChannelsInit();
    initADC(1);
    jshInit();     // Initialize the hardware
    heapVars = (esp_get_free_heap_size() - 40000) / 16;  //calculate space for jsVars **** modified 40,000 to 60,000
    heapVars = heapVars - heapVars % 100; //round to 100
    if(heapVars > 20000) heapVars = 20000;  //WROVER boards have much more RAM, so we set a limit
    jsvInit(heapVars);     // Initialize the variables
    // not sure why this delay is needed?
    vTaskDelay(200 / portTICK_PERIOD_MS);
    jsiInit(true); // Initialize the interactive subsystem
    if(ESP32_Get_NVS_Status(ESP_NETWORK_WIFI­)) jswrap_wifi_restore();  
  [#ifdef](https://forum.espruino.com/sear­ch/?q=%23ifdef) BLUETOOTH
    bluetooth_initDeviceName();
  [#endif](https://forum.espruino.com/sear­ch/?q=%23endif)
    while(1) {
      jsiLoop();   // Perform the primary loop processing
    }
  }
  

  With little or not success, JSVARS reduced, but still not working.

  Hello everybody,
  I tried with different versions of firmware (2.04) and have every time the same issue:

  Uncaught InternalError: Failed! mbedtls_ssl_setup: Not enough memory
  

  >process.env

  Code Testing:

  var ssid = "******";
  var password = "*****";
  var port = 80;
  var wifi = require('Wifi');
  console.log("started");
  wifi.connect(ssid, {password: password}, function() {
      console.log('Connected to Wifi.  IP address is:', wifi.getIP().ip);
      var http = require('http');
      http.get("https://www.google.com", function(res) {
        res.on('data', function(data) {
          console.log(data);
        });
      });
      // wifi.save(); // Next reboot will auto-connect
  });
  

  Full Error:

  I will try to clean the code, and trace the call´s order, and come back again tomorrow. But basically the call to start is in the require(ssd1306) callback.

  Thanks for your help.

  OK, i found it. This SSD1306 module, apparently, need at least 1.5 seconds to stabilize.

  if I plug the USB, connect the IDE and execute "g = require("SSD1306").connect(i2c, start, { height : 32 });" from the console the display update all the information. Looking further to understand why...
