My library already has this patch.
Observing the logs in real time, I noticed lags. It happens that the transfer stops for a few - several seconds. Besides, it is not liquid, it stops for a few seconds every second or so.
Perhaps the reason lies in a completely different layer, the physical layer of the Ethernet driver. Were there such cases? How to track it?
How can I extend the OTA timeout? I think it could help temporarily.
