Disclaimer: still using the HTTPS example, this is the first time I get this far so I might be doing something wrong.

Issue: using version 0.2.7 when executing esp32FOTA.execOTA(); (updatedNeeded is True) I get the following message:

Opening item http://192.168.1.100/ota/test_1-version-1_0_1.bin

I am using an ESP-CAM and have done no previous partition work or anything else than compiling & uploading binaries using arduino/platformIO.

Is the above command supposed to work in my case ?

If not, could I be pointed out to a resource describing the necessary preparatory work on the ESP, step by step ?

Many thanks!

FYI the file used as .bin is firmware.bin found on "C:\PlatformIO\Projects\Espressif ESP32 Dev Module.pio\build\esp32cam"

What is the Tools-> Partition Scheme you are using for this module? Is it one that includes OTA?

[milkywade]

This is the partition scheme being used: https://github.com/espressif/arduino-esp32/blob/master/tools/partitions/default.csv

Also: here is the list of pre-configured partition tables: https://github.com/espressif/arduino-esp32/tree/master/tools/partitions

P.S. Using platform.io on VSCode so particion scheme is in a different place.

[Humancell]

Yep. Ok. I was just curious if it could be the partition wasn't set-up for OTA. And you can hit the URL "http://192.168.1.100/ota/test_1-version-1_0_1.bin" and download the file in your browser?

What options did you set for the config?

P.S. I'm just asking as I got it working on my ESP32 devices and it just worked.

[milkywade]

Hey, thanks. Yes, the URL hits OK using the browser and the file downloads.

Re config, this is what I have:

printConfig()

Name: test_1
Manifest URL:http://192.168.1.100/ota/fota.json
Semantic Version: 1.0.1
Check Sig: false
Unsafe: false
Use Device ID: false
RootCA: false
PubKey: false

fota.json (note I manually change in this file the version to 1.0.2 whenever I want to test the OTA)

[
{
"type": "test_1",
"version": "1.0.1",
"url": "http://192.168.1.100/ota/test_1-version-1_0_2.bin"
}
]

Last, the board is a espcam.

Just compiled using a different IDE: arduino v1.8.19. Uploaded a new version to the ESP32-CAM, compiled again and uploaded "OTA_test_3.ino.bin" to the HTTP server (renamed as test_1-version-1_0_3.bin).

When adjusting the fota.json file to force the OTA process, the ESP32-CAM crashes with error:

What am I doing wrong ? Am I uploading the wrong BIN file ?

[milkywade]

OK. I found it.

As explained here: https://www.esp32.com/viewtopic.php?t=14700 boards.txt describes the esp32-cam as needing a huge_app partition.

esp32cam.build.partitions=huge_app

When I change boards.txt to change it to default (unfortunately, for the ESP32-CAM board, this can _not be done withing the GUI of the IDE), OTA works.

esp32cam.build.partitions=default

My eyes watered a little seeing the first OTA & the version numbers change :-)

Thank you @Humancell for putting me on the track !

P.S. To make it work in VS Code using PlatformIO, I found that you have to add the parameter board_build.partitions to force the partition table in platformio.ini :

[env:esp32cam]
board_build.partitions = default.csv

This is awesome news! It really is amazing to see it work! I travel back and forth between the east and west coasts of the US and I love seeing my test devices reboot and report in with the new firmware version when I'm on the other side of the country!
