Hey Guys, Obviously in that last post there was much going on that I have no idea was occuring. For one thing when I installed the ElegantOTA library (I didn’t notice until I was shutting down) that 3 different Libraries were added for ESPAsyncTCP. So I scrapped it all and started over. It looks much better, however I still have one error in the main.ccp:

argument of type “AsyncWebServer *” is incompatible with parameter of type “ESP8266WebServer *” (aka “esp8266webserver::ESP8266WebServerTemplate *”)
That error has been persistant. Any Clues?

Guys, I finally found the updated ElegantOTA library. Through much searching I found the one listed in this tutorial is deprecated. The author points to a web page that gives a similar identification of ayushsharma82/ElegantOTA@^3.1.6, but when I put that in the ini file, platformio reports parsing errors, and won’t allow it. I then found that it is in the PIO repository listed under ElegantOTA. Installing from there places the proper ID in the ini file. But the problems don’t end there. There are then several errors generated one refering to a line in the AsyncTCP library they are as follows:
1. cannot convert ‘AsyncWebServer‘ to ‘ESP8266WebServer‘ {aka ‘esp8266webserver::ESP8266WebServerTemplate*’}
2. argument of type “AsyncWebServer *” is incompatible with parameter of type “ESP8266WebServer *” (aka “esp8266webserver::ESP8266WebServerTemplate *”)
4. #error For RASPBERRY_PI_PICO_W board using CYW43439 WiFi only.
I’m not sure where to go with all this, and with my limited experience, I’ve never seen PIO generate errors from libraries before. Any Help greatly appreciated.

Hi Rui/Sara. I have been working for a few days trying to get OTA to work on the arduino IDE with some success. In searching for solutions to my problems (mainly that the port is dropped randomly) it was pointed out that PlatformIO worked much better than the IDE; which brought me here. However, when I followed the instructions here, before trying to upload I ran a check compile and got the error:
UnknownPackageError: Could not find the package with ‘ayushsharma82/AsyncElegantOTA @ ^2.2.5’ requirements for your system ‘windows_amd64’
If I look for the library in PIO, it’s not there, so I don’t know where to get it. Can you steer me in the right direction? Thanks

Sara/Rui,
read
Thank you for this tutorial. I need to read the instructions more carefully and realize that reading and reading again will help me keep from getting frustrated. I had a hard time compiling the program at first but after rereading the instructions it was clear that some of your instructions were a preview of more detailed instructions later on.

Hi.
This example is for ESP8266, not for ESP32.
For the ESP32, check this tutorial instead: https://randomnerdtutorials.com/esp32-ota-over-the-air-vs-code/

For the littlefs example to work, do I need to create the partition on the ESP32 first before this example can run properly? Is the process missing from the code examples above?
At the moment I get:-

.pio\libdeps\esp32dev\LittleFS_esp32\src\lfs.c:1076:error: Corrupted dir pair at {0x0, 0x1}
E (34) esp_littlefs: mount failed, (-84)
E (34) esp_littlefs: Failed to initialize LittleFS
[E][LittleFS.cpp:90] begin(): Mounting LITTLEFS failed! Error: -1

Hi Sara,

I just purchased a new Dell laptop and installed VSCode/PlatformIO, creating a new project, added the three libraries and the provided sample code. I get the same panic.

Regards,
Mark

Hi again.
Taking that into account, it seems there must be some issue with your base code.

In reply to Sara Santos. Sara/Rui, I made a bad assumption that the WiFiManager or another library was causing the panic. I created a new PlatformIO project, including AsyncElegantOTA, me-no-dev/ESPAsyncWebServer, me-no-dev/ESPAsyncTCP, and your example in this tutorial and get the same panic when the .bin completes uploading.

Hi.
Yes, I think it should work, but I haven’t tested it in that scenario.
