Although my ESP8266 is present in Tools>PORT option along with the local ip address. (My esp8266 is present in the network but still ArduinoIDE shows No response from Device error every time i upload the same program. )
This program worked for the very first time that too via OTA.

Are you able to test it on Windows 7 machine?
At this point I do not have any better ideas.

No way. tried on Win 7 64bit with esp 1.6.5 stable core and esp 1.6.5 staging core but same result :

What version of phyton are you using? I’m using 2.7.10. What kind of esp ? How is it connected ? I don’t have any ideas where to bang my head !
Thanks
Dario

Also tried to erase eeprom first.

I can’t believe how close you are to get this working and how simple should be the reason so it is not working 😄

Here is my python:

I am currently using NodeMCU boards, namely LoLin and Amica as well as ESP8266-EVB by Olimex.

All are working without any issues with DNS_SD_Arduino_OTA.ino and esp8266/Arduino release 1.6.5-1160-gef26c5f (of Sep 30, 2015).

I have been testing OTA back and forth when writing first three chapters of: https://github.com/esp8266/Arduino/blob/master/doc/ota_updates/ota_updates.md and was always getting repeatable results and stable operation of OTA. This is assuming I use compatible s/w on each step.

I am wondering if you see anything on serial monitor when OTA fails. If successful, the output on serial monitor looks like below:

If there are no clues on serial monitor and you are not moving any way forward I would put it aside for a while and try other way of doing OTA: https://github.com/esp8266/Arduino/blob/master/doc/ota_updates/ota_updates.md#web-browser. If this fails as well maybe the problem is with your Wi-Fi network / router.

Good luck and I am looking forward to seeing how you handle this issue 👍

Changing SPIFFS size on each OTA update #2214

Problem and solution

The ESP8266 needed to be connected to (either pinged or a failed upload) between successful uploads. Using to another WIFI network solved the issue. I’m still working on how to resolve it without switching networks.

Original post:

Hardware

Hardware: ESP-12f
Core Version: 2.3.0

Description

Every time I update over OTA I need to change the SPIFFS size, otherwise I get [ERROR]: No answer

Settings in IDE

Module: Generic ESP8266 Module?
Flash Size: 4MB/1MB and 4MB/3MB
CPU Frequency: 80Mhz
Flash Mode: dio or qio (it doesn’t seem to make a difference, what is it?)
Flash Frequency: 40Mhz
Upload Using: OTA
Reset Method: ck

Sketch

Debug Messages

The text was updated successfully, but these errors were encountered:

• Where / how do you «need to change the SPIFFS size»? Could you provide exact steps to replicate this issue?
• Does the issue occur with original BasicOTA.ino example?

I’m using BasicOTA.ino modified to flash pin 13. I need to alternate uploading with 4MB/1MB and 4MB/3MB flash sizes or I get the [ERROR]: No Answer message. Switching to another memory setting also fails but allows me to use the same 4MB option again. I also don’t think it has to do with recompilation, as changing sketches still doesn’t work unless I switch to the other 4MB option.

Does the issue occur with original BasicOTA.ino example (without 1000 ms delay in loop())?

I don’t know if this is helpful, but installing a different version of the board between uploads lets me upload with the same settings.

I have just loaded couple of times your sketch using each time the same settings like below:

On external serial terminal I see each time log as follows:

I wonder what is the log that you see when upload is successful and when it fails?

Edit: For this test I have been using ESP-12 and esp8266 / Arduino core 2.3.0.

After playing around, it looks like I can use the same memory settings, as long I do it twice (upload, fails, upload). I also checked, it’s not a timing thing. Waiting awhile still doesn’t work. Failure brings up nothing, as you would expect with the No answer response. Success:

Weird development, instead of doing a failed upload between successful ones, I can also just ping it. (Again, same action whether or not I have my LED blinking code) It seems the ESP8266 just needs to get connected to by something before uploading works. I hope you aren’t as miffed as me!

I am glad you were able to remove IDE settings from the equation and narrow down the issue to connection problem. This means you are progressing by having less variables to check 👍

I believe symptoms you describe may indicate issue with network or PC configuration. Having another Wi-Fi router I would set up a separate network to check it out. I would use generic router configuration without any firewall, etc. After all internet connection is not required for this test at all. I would also try another PC.

As a side note, I would like to clarify the boot mode you are getting rst cause:2 , that indicate you were doing hardware reset of your board. Normally, except for the reset after initial upload with serial, you do not need to hard reset your ESP for any OTA uploads at all. Below is a log of several subsequent uploads I have made without any retries, pinging, etc. Do you need to do any hard resets to make the OTA working?

I’m trying to get OTA updates working on a new design using the ArduinoOTA component in the ESP8266 library on github. I have an ESP-07 attached via an FTDI adapter to a Win10 system running PlatformIO inside Atom.

I have built the example sketch as shown below and it uploads via the serial port and runs just fine. However, after enabling OTA upload in my platform.ini file, it always fails with no response from the ESP. I have scoured the web and tried the solutions that have helped others including setting a specific port number, enabling authentication (which fails to authenticate), and have tried different IP addresses (static and DHCP). I started with a board = esp07 and the same env, and have tried switching to nodemcu and nodemcuv2 without any change in behavior. I don’t know how to troubleshoot this any further.

My sketch:

Code: Select allinclude <ESP8266WiFi.h>
#include <ESP8266mDNS.h>
#include <WiFiUdp.h>
#include <ArduinoOTA.h>

const char* ssid = ".....";
const char* password = ".....";
const IPAddress me(10, 248, 0, 171);
const IPAddress gateway(10, 248, 0, 1);
const IPAddress dnsServer(10, 248, 0, 1);
const IPAddress subnetMask(10, 248, 0, 171);

void setup() {
  Serial.begin(115200);
  Serial.println("Booting");

  WiFi.mode(WIFI_STA);
  WiFi.config(me, gateway, subnetMask);
  WiFi.begin(ssid, password);
  while (WiFi.waitForConnectResult() != WL_CONNECTED) {
    Serial.println("Connection Failed! Rebooting...");
    delay(5000);
    ESP.restart();
  }

  // Port defaults to 8266
  ArduinoOTA.setPort(8266);

  // Hostname defaults to esp8266-[ChipID]
  ArduinoOTA.setHostname("myesp8266");

  // 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);
  });
  ArduinoOTA.onEnd([]() {
    Serial.println("nEnd");
  });
  ArduinoOTA.onProgress([](unsigned int progress, unsigned int total) {
    Serial.printf("Progress: %u%%r", (progress / (total / 100)));
  });
  ArduinoOTA.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();
  Serial.println("Alive!");
  delay(1000);
}

My platformio.ini file:

Code: Select all[env:nodemcuv2]
platform = espressif8266
board = nodemcuv2 ;esp07
framework = arduino
upload_port = 10.248.0.171
;upload_flags = --auth=admin --port=8266
upload_flags = --port=8266


And, the error I get:

Hi,

I followed this guide

https://github.com/esp8266/Arduino/blob/master/doc/ota_updates/readme.md

to get OTA working on ESP8266. I can flash and re-upload (over WIFI) BasicOTA.ino without issues. Once I upload GatewayESP8266OTA.ino and afterwards try to upload another sketch I receive message «[ERROR]: No Answer».

I am using Arduino IDE 1.6.9, MySensors 2.0.0, ESP Boards 2.3.0.

---

@niccodemi OTA needs to be added to the gateway sketch (and all other sketches where you want OTA capability).

From the instructions you linked to:
Note: To be able to upload your sketch over and over again using OTA, you need to embed OTA routines inside. Please use BasicOTA.ino as an example.

---

@mfalkvidd ok, I’ll try. I thought that’s what GatewayESP8266OTA sketch was supposed to do.

---

@niccodemi yes you are right. Sorry about that. The OTA stuff is already included in GatewayESP8266OTA. Then it should work.

What output do you get on serial when you try updating?
Have you modified GatewayESP8266OTA or are you using the example without modification? (except setting ssid and password)
Does the gateway work (can you ping it, does it forward messages)?

---

@mfalkvidd I reinstalled Arduino IDE and libraries and that seems to fixed the issue.

---

Strange. But great that it got fixed

---

Hello all,

Just to share my experience with OTA for the ESP8266 and VisualMicro for future reference, I think that there is no need to create a new topic as the search button works pretty well

I’ve followed the toturials:
http://esp8266.github.io/Arduino/versions/2.2.0-rc1/doc/ota_updates/readme.html
http://www.visualmicro.com/page/esp8266.aspx

Setting the IP of the ESP8266 works pretty well but I was not able to make the bonjour service to work maybe because of windows 10 ou Kaspersky firewall.

The Issue that I’ve faced was after uploading the sketch, the ESP8266 did just stuck at boot or entered a bootloop and I’ve got this message «rst cause:4, boot mode:(3,6)»

If you’re facing the same or a similar issue I recommend checking your power source, I’ve added a 470uF capacitor between Vin and GND and start using a proper power supply even when connected to USB and the problem is gone.

Source: https://github.com/esp8266/Arduino/issues/1328

---

Hi, is it okay if I ask how can I embed OTA code to my arduino sketch for me to be able to upload over and over again? Im working for Temperature Sensor. Thanks you.

---

@vanjsy Use the sketch here — you can use it as is (change ssid and pwd of course) or add the missing pieces to yours.
