ESP32 OTA password problems
Dec 14th, 2024 at 12:18pm
Print Post  
Hi,
I have a project that uses OTA to update an ESP32.
The password for OTA is set correctly in the Arduino OTA code.
The first time I tried to upload (without a board.txt file) it asked for a password, which I gave but typed incorrectly.
I then created a board.txt file with network.password=<correct password>
Whenever I try to do an upload it continues to use the old incorrect password (as seen in the verbose output)
If I change the password in board.txt it does not change when trying to upload.
I removed the board.txt and it still tries to upload with security.
I did a clean and rebuild, still the same.

It appears the password is being cached somewhere but I have no idea where.
If I remember it was historically always read from the board.txt file in the project.

Any ideas?

More info:
It definitely appears it is cached. 
Closing VS and re opening it with the project and the password is correctly read from board.txt however making any changes in board.txt are not picked up until VS is closed and opened again.

Thanks for the report and noting the workaround of restarting VS.

We will look into this and update when a fix is available.

Have you tried using a ArduinoOTA.setPasswordHash
i never get it to work since some time ....
But it is not visual micro related i think ?

I´m pretty sure it is a VM problem.
When I do an OTA upload I see the password in the command string in the output window. If I change the password in the board.txt the password in the command string stays the same - implies to me that it is cached and not read on each upload.

Only way to reset it is to close/open Visual Studio, it then picks up the new password.

I have no problems using OTA updates, work perfectly for me as long as the passwords are the same Smiley

Thanks for the updates, can you attach the build and upload log from your machine with the below options enabled:
  • vMicro > Compiler > Verbose
  • vMicro > Compiler > Show Build Properties
  • vMicro > Uploader > Verbose

Here it is but I don´t know if it will help much.
Simply do an upload with any password then change the password in board.txt, re do the upload and you will see the password in the espota.exe command string will not have changed to the new password from the board.txt

From board.txt
network.password=j3ss1camEMS2

Thanks for the log and detail, we thought the issue with the board.txt changes had been fixed in a recent release (and tested OK), however this is clearly not the case.

We will update this thread when there is a fix for this issue.

The latest release (25.0120.4) should resolve this issue fully, and can be downloaded from the top of the below board:
https://www.visualmicro.com/forums/YaBB.pl?board=VS_ARDUINO_EXT_RELEASES

Let us know if you have any further issues with the board.txt entries not updating during the session.

..or maybe not. Something strange is going on. It worked a few times but then for no reason it has lost all authentication on code uploads but on spiffs uploads it is ok. Restarting VS has not fixed it.

LITTLEFS Uploading Image...

   Sending invitation to 192.168.0.203
   Authenticating...OK


Output from code upload:

Uploading via Bootloader

\espota.exe -i 192.168.0.203 -p 3232 "--auth=" -f 
Sending invitation to 192.168.0.203 
Authenticating...FAIL
08:31:17 [ERROR]: Authentication Failed
The uploader process failed


For some reason the forum is truncating the commands but the authentication is not there in the code upload.

Thanks for the update.

Can you add the below entry to your local board.txt file:
network.auth_upload=yes

And try the build & upload again?
