Using Update Server - AutoConnect for ESP/ESP32

Once I power up after loading my app, will I still be able to update the app over the air? That explains a lot! I installed Python 2. However, I dont see the proper ESP wifi port. What is the role of Python in this tutorial? Or with the Arduino IDE serial monitor. If it does not help, check your firewall and router settings. Itsss Really a good job!

But I have a doubt can we program twice or thrice or as many time times through OTA??? Yes, you can upload unlimited number of times, but the core OTA code should be in all the sketches that you upload. It uploaded OK and showed in the Serial Monitor that it was connected, but there was subsequently no other option showing under ports only the com port in use.

But I need to change it to a new one. How do I add it? You might consider upgrade the Sonoff memory…. Seems like a lot of people are running into password issues when trying to open the serial monitor over the air. Anyone have any ideas? I tried all the obvious passwords, made sure the password line in the sample code is commented out. As before.

My previous post may have been slightly misleading. I get as far as step Press the Upload button … and I get the following error: java. But I have python installed and it is in the path. For example, I can open a CMD window and type python, and it runs. Any ideas? I fixed the Python not found problem. I had to uninstall all previous Python installs.

I should have looked at the Path variable before I did this to see what it had in it, maybe a reference to one of the earlier installs. But now it all works — at least with your test app. Now to try it with my own app. Fantastic, Rui! I was afraid that I would have problems because my app makes the an Access Point with no password, while my network connection is a hotspot running on my phone and it has a different SSID and also a password. But DAMN, it all works. I frequently need to update the software, so being able to do this without taking the enclosure apart and hooking up a USB cable is a really nice thing for me.

Thanks for the tutorial! I am having problems now. I run into two different problems. So that is problem 1. When the network port does appear, the IP address that is part of the port address is always the same: But if the IP addresses match, then the update works fine. So I am assuming that the OTA loader saves the IP address it finds and expects the to always be at that address, which it is not. I guess that is obvious from the fact that it sometimes works. PY file directly, parametering in a.

I am double posting these questions here and on the FB site to get a wider exposure in hopes that I can get this problem solved soon. But from running an IP scanner, I can verify that the port exists and is live. The odd thing is that maybe once in twenty times that I open an instance of the IDE, the port shows up. The rest of the time it does not. Any ideas on this? I posted this problem to the Arduino forum also. I found the solution! I did not find the root problem but I found the solution.

Restarting the Bonjour Service is the solution. I do not know why that works but it does. The ESP appears in the port list! Just thought you would like to know! Too soon! It turns out that restarting the Bonjour Service only worked once — ust like other tries at a solution that I thought were the answer! What the hell is going on with this thing? For some reason, adding blink code 4 lines causes the port not to be found.

It is working for me. Since GPIO1 is also used as serial line. Search for the drivers and install it on your operating system.

First time you need to download this sketch using serial port. However, before downloading first time using serial, you need to make sure to install the board support package for ESP in Arduino. It keeps rebooting after doing what? Make sure you are using a reliable power supply to power your ESP board.

Thanks for asking, Rui. Hi Rick. Yes, if you want to be able to upload code over the air in the future, you need to include OTA code in all your sketches. I had a problem but I found a solution, however crude. There was an error message when I tried to upload code to espxxxxxx.

The loader espota. Search for in upper right search box. One of the choices is esp by ESP community. The version that was already installed was 2. I clicked on the Select Version box and selected version 2.

Then it loaded. Thanks for sharing the solution to your problem. It may be useful for others. Thank you so much. The WeMos board is available here: banggood. The identical RobotDyn board is available here: robotdyn. Hi Ron. If anyone here knows something about this topic, please share. I had a novel problem that might help others.

The same exact code in my program in the same places almost never showed the network port. Background: after setup I run a 5 minute routine and then go into a lower-power mode not Deep-sleep for 30 minutes, and then the main loop starts again with turning the WiFi on since it just came out of low-power mode. I tried simply moving the ArduinoOTA.

Chapters below provide additional information regarding security and safety of OTA process. Module has to be exposed wirelessly to get it updated with a new sketch. That poses chances of module being violently hacked and loaded with some other code. To reduce likelihood of being hacked consider protecting your uploads with a password, selecting certain OTA port, etc. Check functionality provided with ArduinoOTA library that may improve security:. Certain protection functionality is already built in and do not require any additional coding by developer.

ArduinoOTA and espota. Make your own risk analysis and depending on application decide what library functions to implement. If required consider implementation of other means of protection from being hacked, e. Then module is restarted and a new sketch executed.

Analyse and test how it affects functionality of your existing and new sketch. If ESP is placed in remote location and controlling some equipment, you should put additional attention what happens if operation of this equipment is suddenly interrupted by update process.

Therefore decide how to put this equipment into safe state before starting the update. For instance your module may be controlling a garden watering system in a sequence. If this sequence is not properly shut down and a water valve left open, your garden may be flooded if this valve is not closed after OTA is finished and module restarts.

Uploading modules wirelessly from Arduino IDE is intended for the following typical scenarios: - during firmware development as a quicker alternative to loading over a serial - for updating small quantity of modules - only if modules are available on the same network as the computer with Arduino IDE. This particular configuration is easier to configure in Arduino IDE and therefore suggested for less experienced users.

It soon will be depreciated once implementation below is fully released. This configuration features preliminary build of Arduino IDE and is intended for more experienced users.

Please mid your step. Python 2. Note: This sketch is available only for 1. You can easily set up a Python 2 or 3 environment. If you are using a Mac, you already have the Python 2 environment.

In the case of Windows OS, it is necessary to install the Python environment intentionally. Please refer to the Python official page to install Python in your environment. Deploy the binary sketch files Use the Arduino IDE to output a binary file of sketches and deploy it 3 under the update server.

Esp8266 firmware ota obtain the file navigate to directory used by Arduino IDE to store results of compilation.

You can check the path to this file in compilation log shown in IDE debug window as marked below. This is because module has been loaded again with the same code — first using serial port, and then using OTA. Once you are comfortable with this procedure go ahead and modify WebUpdater. You can also add OTA routines to your own sketch following guidelines in Implementation Overview above. If this is done Esp8266 firmware ota you should Esp8266 firmware ota always able to upload new sketch over the previous one using a web browser.

In case OTA update fails dead after entering modifications in your sketch, you Esp8266 firmware ota always recover module by loading it over a serial port. Then diagnose the issue with sketch using Serial Monitor. Once the issue is fixed try OTA again. It is Esp8266 firmware ota to download updates from every IP or domain address on the network or Internet.

Its possible to point update function to a script at the server. If version string argument is given, it will be sent to the server. Server side script can use this to check if update should be performed. Server side script can respond as follows: - response codeand send the firmware image, - or response code to notify ESP that no update is required.

For advanced update management a script needs to run at the server side, for example a PHP script. With this information the script now can check if a update is needed. It is also possible to deliver different binaries based on the MAC address for example. Updater is in the Core and deals with writing the firmware to the flash, checking its integrity and telling the bootloader to load the new firmware on the next boot.
