ESP32 OTA very flakey

Hello! I have been trying to make the OTA example found here work:

http://docs.platformio.org/en/latest/platforms/espressif32.html#over-the-air-ota-update https://github.com/espressif/arduino-esp32/tree/master/libraries/ArduinoOTA/examples/BasicOTA

I can get the example to upload every 10 tries or so, but not consistently

I am using PlatformIDE on VSCode on macOS Mojave

Here are the versions that I am running:

VSCode: 1.31.1 PlatformIO: 3.6.4

I have tried disabling my firewall but that did not help. Any help or further guidance would be appreciated, thank you!

Here is the code that I am using, it is identical to the OTA example:

#include <WiFi.h>
#include <ESPmDNS.h>
#include <WiFiUdp.h>
#include <ArduinoOTA.h>

const char* ssid = "HOME-C44A-2.4";
const char* password = "3PD94CA9TFDV34AT";

void setup() {
  Serial.begin(115200);
  Serial.println("Booting");
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
  while (WiFi.waitForConnectResult() != WL_CONNECTED) {
    Serial.println("Connection Failed! Rebooting...");
    delay(5000);
    ESP.restart();
  }

  // Port defaults to 3232
  // ArduinoOTA.setPort(3232);

  // Hostname defaults to esp3232-[MAC]
  // ArduinoOTA.setHostname("myesp32");

  // No authentication by default
  // ArduinoOTA.setPassword("admin");

  // Password can be set with it's md5 value as well
  // MD5(admin) = 21232f297a57a5a743894a0e4a801fc3
  // ArduinoOTA.setPasswordHash("21232f297a57a5a743894a0e4a801fc3");

  ArduinoOTA
    .onStart([]() {
      String type;
      if (ArduinoOTA.getCommand() == U_FLASH)
        type = "sketch";
      else // U_SPIFFS
        type = "filesystem";

      // NOTE: if updating SPIFFS this would be the place to unmount SPIFFS using SPIFFS.end()
      Serial.println("Start updating " + type);
    })
    .onEnd([]() {
      Serial.println("\nEnd");
    })
    .onProgress([](unsigned int progress, unsigned int total) {
      Serial.printf("Progress: %u%%\r", (progress / (total / 100)));
    })
    .onError([](ota_error_t error) {
      Serial.printf("Error[%u]: ", error);
      if (error == OTA_AUTH_ERROR) Serial.println("Auth Failed");
      else if (error == OTA_BEGIN_ERROR) Serial.println("Begin Failed");
      else if (error == OTA_CONNECT_ERROR) Serial.println("Connect Failed");
      else if (error == OTA_RECEIVE_ERROR) Serial.println("Receive Failed");
      else if (error == OTA_END_ERROR) Serial.println("End Failed");
    });

  ArduinoOTA.begin();

  Serial.println("Ready");
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  ArduinoOTA.handle();
}

Here is my platform.ini

[env:esp32thing]
platform = espressif32
board = esp32thing
framework = arduino
monitor_speed = 115200

Here is the command I am using to upload

platformio run -t upload --upload-port 10.0.0.132

I’d definitely give other power supplies a shot. The 5v voltage regulators on these boards can be finicky and while a PSU may be in spec, it’s starting voltage or even running voltage may be below what the regulator needs to run reliably. Also, some companies like to implement things slightly off spec, too; the Nintendo Switch PSU is a great example of that. A generic, 1A/5W or similar PSU may be your best bet for something like this. May need to try every wall wort you’ve got hoarded away, though 😉 I’d also try running in it on just a LiPo battery, which should bypass that regulator. Worth a shot 😃.
