Problem Description

This is a problem related to the popular Robotdyn D1R2 boards.

Using the standard BasicOTA from the examples, the Robotdyn D1R2 stops OTA uploading after 25-50% when the AP is three meters away. Upload does not even start on APs that are farther away. All other wifi functions work just fine.Tested it on seven of these boards.

The same code on e.g., a Robotdyn D1 mini or LOLIN ESP32 (of course with different libraries) just works.

I also installed the esp8266 library from the Board manager (after uninstalling the github tree) and exactly the same thing happens.

What surprises me is that I can not find references to this problem on the internet, although the Robotdyn D1R2 is a very popular board.

From your description of the same code working on other boards, this doesn't seem to be a core issue. Your best bet would be to use esp8266.com or https://gitter.im/esp8266/Arduino, or the manufacturer. Good luck!

As said in #5990 (comment) and if the issue is easily repeatable, a tcpdump trace could be helpful for #4054 and #6369. It can be done with the integrated netdump library.

Yesterday I tried to contact support@robotdyn.com, but the mailaddress does not exist (!).

I never used tcpdump and would not know what to look for. I started "tcpdump host 192.168.178.50" on the commandline while uploading the sketch both for the failing D1R2 and the working D1-mini and captured the output, but I don't know what I am looking at. I am a bit reluctant to copy the output here, but here it is...

Thanks for this dump @paai.
What we can see is that at the end ESP is asking for retransmission from 30529, that is honoured by PC but never acknowledged by esp then PC shuts down the connection. It'll hopefully help to understand while reading between the lines of espota.py and the ArduinoOTA library.

Thank you. But I am rapidly getting out of my depth here and I don't speak python (the curly braces on the keyboard are there for a good reason!).
The bottom line seems to be that something is broken in Robotdyn D1R2 boards that cannot be easily remedied. But it is a popular board and has been around or at least four years, so it is peculiar that nobody stumbled over it before. Ah well... Thank you all for helping me.
