Arduino Mega not showing up in "network ports"

[JaspervanKol]

A few months back I had burned the bootloader to a few Arduino Mega's and I could upload a sketch using OTA using ethernet. Now I wanted to update the software and I can't see the Arduino's in the "network ports" section. I can see all my ESP's as shown below but not my Arduino's.

I already tried a new Arduino and burned the bootloader again but also this Arduino is not showing up in the list. Also the example sketch "OTEthernet" does not work, I can see the debug log in the serial that it is connected with an IP address but still not showing up in the "network ports" section.

I am using the following lib's and versions: Arduino IDE 2.2.1 ArduinoOTA 1.0.12 MyBoards https://github.com/jandrassy/my_boards

Does somebody know how to fix this issue?

[JAndrassy]

do you have the IDE 2 updates in my_boards?

I downloaded my_boards back in late september 2023 and it was working with Arduino IDE 2. To check for sure, I downloaded my_boards again (today 11-01-2024) and burned the bootloader to a new Arduino Mega. But still with the OTA example sketch I don't see it appear in the "network ports"

Okay very weird behavior...

I waited for around 5 minutes while doing nothing in the IDE. Then I tried again, and there it was in the "network ports". But after uploading a sketch successfully they were already gone. See picture below of the successful flash but no entries (Arduino Mega) in the "network ports"

While still connected to the port "192.168.2.184" uploads are possible. But I can't connect to another one (Arduino Mega). After that they didn't show again...

I followed the instructions and eddited the "programmers.txt" located in "C:\Users\jaspe\Documents\Arduino\hardware\my_boards\avr" to:

arduinoOTA215.name=Arduino OTA (192.168.2.215)
arduinoOTA215.program.tool=arduinoOTA
arduinoOTA215.ip=192.168.2.215

arduinoOTA218.name=Arduino OTA (192.168.2.218)
arduinoOTA218.program.tool=arduinoOTA
arduinoOTA218.ip=192.168.2.218

arduinoOTA237.name=Arduino OTA (192.168.2.237)
arduinoOTA237.program.tool=arduinoOTA
arduinoOTA237.ip=192.168.2.237

arduinoOTA238.name=Arduino OTA (192.168.2.238)
arduinoOTA238.program.tool=arduinoOTA
arduinoOTA238.ip=192.168.2.238

arduinoOTA239.name=Arduino OTA (192.168.2.239)
arduinoOTA239.program.tool=arduinoOTA
arduinoOTA239.ip=192.168.2.239

But in de IDE at "programmer" I only see the old entry of the file:

Arduino OTA (192.168.1.102)
Arduino OTA (192.168.1.104)

When I remove the whole "my_boards" folder, all the entries in "board" are gone but the entries in "programmer" are still there. Is there another file I need to edit or is the IDE not fully updating?

[JaspervanKol]

I found out that the IDE is caching some files. I deleted the folder "arduino-ide" located in "C:\Users\jaspe\AppData\Roaming". After restarting the IDE all the programmers showed up!

Now I have another problem where it is defaulting to a standard username & password while using "Upload Using Programmer":

"C:\Users\jaspe\Documents\Arduino\hardware\my_boards/tools/arduinoOTA.exe" -address 192.168.2.218 -port 65280 -t 30 -username arduino -password password -sketch "C:\Users\jaspe\AppData\Local\Temp\arduino\sketches\864D53D4FCD5ED644FFD1B948E0F06EC/Control_v4.0.ino.bin" -upload /sketch -b
Connecting to board ...  done
Uploading sketch ...  done
Flashing sketch ...  done
Error flashing the sketch:Unauthorized
Failed programming: uploading error: exit status 1

Normally it will ask for the password, right?

[JAndrassy]

sorry, not for programmer. you have to put the password into platform.txt command. maybe it is possible to put it in programmers.txt

[JaspervanKol]

Ah ok, got it! It works now
