In this video, I would like to remind you of a handy ESP32 concept: Over the air or OTA update. A simple and efficient replacement of the Serial cable for devices which are not easily reachable, or for barebone ESP32 modules. And, as usual, I will add a few tricks and helpers.
In this video, we will:
- Learn how to use ESP32 OTA
- Create a basic sketch template for all our new projects
- I will show you some tricks like remote debugging
- If this simple OTA is not enough, I will show you other frameworks
- And, as usual, I included a “one last thing”

The part that stumped me was the way PlatformIO automatically selects the upload connection. Normally that is a good thing but I wanted to test the OTA connection.

Very useful video, sir. I'm happy to see more code taking advantage of the ESP32. Dev boards are close enough to the 8266 in price that it's worth using the 32s even for simple projects.

Instead of putting `ArduinoOTA.handle()` in your main loop, you should be able to set up an independant timer interrupt and have it run from there, as extra insurance in case `loop` (or for that matter, the rest of `setup`) crashes or delays or gets stuck in some way. edit: Actually you do address this briefly with your comment about setting up an RTOS task, which is probably a "more proper" way to do it than a raw interrupt.
Always enjoy your tutorials and your github contributions. Thanks for the time and effort you put into these.

Very interesting. I also have a trick for when you use a battery driven device that sleeps a lot, e.g. a sensor like the bme680. In that case loop is never reached and the device goes to sleep very fast. So, I use a loop in the setup that looks for the bme680 and in that loop I add the OTA handle. All I have to do is disconnect the sensor and the device keeps looping and I can connect via OTA. You could use a switch or button to disconnect the sensor.

Actually there are two versions of OTA: 1. Arduino OTA, where initiator is Arduino IDE, so you should be in the same network; 2. HTTP OTA, where you have to code trigger, but then device downloads image from http server (may be served as a static file, but better to use something that adds checksum headers, like mine esp-ota-server). That method used by Tasmota and TasmoAdmin to update devices.

Hi Andreas, very useful video, as always. You've helped me a lot with my projects! I wanted to mention a correction to your description of OTA. It appears that the ESP32 maintains two areas of memory, OTA1 and OTA2. The Esspressif OTA mechanism always loads the new firmware in the unused portion, and, if successful, switches over the boot pointer to the new area of memory. Thus the previous firmware is not written over as implied in the video, and is available for a rollback. This from docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/ota.html Again, thanks for all your help, and also, Grüezi from Yverdon!

The use of delay() inside a task will cause busy waititng and makes your system less real-time. The task will not yield to lower priority tasks so vTaskDelay() is preferred over delay(). However, your time will delay in increments of 15 ms so you may want to also use millis() to make it tighter
@AndreasSpiess
2 жыл бұрын
You are right. I read somewhere that delay() is replaced with vTaskDelay() by the compiler (which would make sense). All my tests with RTOS showed that the ESP32 is way too fast for all tasks I created and had to wait most of the time anyway.

Just 2 suggestions for improvement: 1- incorporate the ArduinoOTA.setHostname() call into the setupOTA() function (which has then to be called with a hostname parameter), 2- append the lower 3 bytes of the MAC address to the OTA hostname. This will help identifying devices if you happen to have more than one device running the same sketch in your network.

I got the ESP-32 ota running on VSC. Unlike the Arduino IDE the port has to be defined differently. In VNC you can see the ports under platformio, home (bottom left the little house), Devices and then the tab Multicast DNS. Or you can search e.g. in your router for the IP of ESP. To use them you have to change the platformio.ini. Enter the current IP address of the ESP here. Example: upload_port = 192.168.10.119 If you want to use usb again, just put a in front of the upload_port.

This is a great video. Best explanation on how to do it. I know I'm a little late but credit where credit is due. I use the wemos d1 and have never had to reset after an ota update. My only complaint is that espressif should've released a more powerful board by now. They're the best other than a pi zero or whatever the new wifi mini pi is called. Anything pi related in Canada that isn't a Pico is at least 115 dollars where as an esp32 is about 20 now. More program memory and a faster cpu like the teensy has been doing for years but the teensy is 60cad.

@@Retrocomputernerd Hi, You need to manually unzip the file and copy the files to your arduino library folder. BTW - I have just noticed I give the wrong password in the instructions, it should be 12345678 I have just uploaded a newer version of the sketch which asks for a password to access OTA (Not very secure but a lot better than nothing)

Nice, i can use this for the solar weatherstation ( with bme280 and pms50003) which i develop now One Question: how can we OTA the esp32 when we use deepsleep? Yes, RTOS is also very interesting subject , special when to use or not to use? Maybe just use a scheduler?? Maybe you should explain about lockups and not putting watchdog triggers in a seperate task! Thanks for your good work Ron

You could add a switch to manually switch off deepsleep mode, if you have access to the weather station. Otherwise configure 15 min. each day for flashing e.g. 12:00 to 12:15.

DO7H, good suggestion. It makes the program a bit more complicated, need exact time and have no internet connection? The idea is that weatherunit hangs somewhere remote at a pole.
Hi Andreas, great video as always! Do you know if this is also possible with VS Code and platformio? I completely switched over from the Arduino ide (which is great for starters, but not so much when you have large and diverse projects.

Thanks Andreas, your chosen topics are always interesting and very relevant. OTA is simpler than I thought. By the way, at the start of your videos are you saying "Greeting KZreadrs" or "Pretty KZreadrs"? Either is fine 😁

Hello Professor Spiess: How about using MQTT, CoAP or even raw UDP instead of Telnet, so we can debug anywhere on the world? It would be nice to see a video of you comparing the performance and latency between TCP and UDP debugging to some broker or even a remote CoAP server. It will be great for those people who don't want to do port forwarding on their routers to access the Telnet server over the Internet. Congratulations for your great master classes! Best Regards!

There are many issues with this. It's ok if you are learning stuff or playing around. If you want a real device running 24/7 it's good idea to put OTA stuff into separate code flow (e.g. enabled only if jumper/button is active on power up). What this gives you is that you don't litter your main code with ArduinoOTA.handle() and some security (accidental overwrite and/or resistance to malware abusing devices like this).

And here I was, wondering if something like a watchdog timer could be used to call the OTA handler. You beat me to it; I forgot about the RTOS aspect of the ESP32. It seems natural to run that as its own periodic task. I'd be worried about copying the call throughout my code -- later wonder "What's this doing here?" and delete it, in the name of "optimizing." 😁
