i try a step by step to increasing the DMA_RX_BUF_NUM in the MENUCONFIG
10..12..15..18..20 this helps me in first step and i think the 15 would be enough. i will try this procedure for now a longer time and update here for success or any. if you have any other suggestion plz let me know.
best wishes rudi ;-)
edit: no - this helps not. so can someone look into this please? if there have nobody time for it - please inform - so i will look deeper by self or switch toi client mode for now or using other AP src. thank you.

EDIT: temporary solved but please let it open for a while Last Update: 2019-March-12 @projectgus
it is a routing/arp problem in windows systems if you have not right configured your public and privat network adapter - i solved this by test on a fresh windows system and switch only one adapter (rj45) so the LAN8720 get the IP from this windows RJ45 and the routing was done by windows fine. now there is no more stuck again.
i will look deeper in the other windows system cause there must be a wrong routing setup or arp entry or anything. let me check next time. if i find out detailed i will post here all steps i did. there is no leak in the buffering itself, all data flys very fine. thank you for the tip with WireShark - did not use it on sender and receiver, allway only one way :) - but this was a good tip to check on sender and receiver. so the data are fine -
only this windows routing ( tracert it ) is very contaminated by eternal back and forth setups and more frequent setups and has not always resolved cleanly or entries (gtw, routings) were not always deleted cleanly all ok Angus but please let it open for a while - i will update the thing here.
amazing work! best wishes rudi
Hi
the Ethernet to wifi station data forwarding demo works very well with an extern Wifi Hotspot. same doing to use the esp32 as own Wifi Hotspot and the Ethernet to wifi softap data forwarding demo the things works at begin, then after a while of continous stream data 3-5 seconds the stream data becomes a mess.
after a new refresh request the stream begin to work ok and then it work for 3-5 seconds and the mess begins again.
i did not look deeper in the handle of FiFo or ringbuffer, which use the Ethernet to wifi softap data forwarding demo perhabs. but can you please check or say, can we flush the data ringbuffer or can we setup with more buffer that the datastream does not go confuse anymore`?
sry - the wifi things are in a blob bin so i can't do anything on a normal way to check the things
My example Setup:
using the ESP32 and LAN8720 works well with the setup demo, works well with the Station Demo. the hardware setup is not the problem - it works very fine.
just only change from Station to softAP mode works 3-5 seconds that the stream gets a mess.
i use the original demo code without any change
Symbolic Ethernet to wifi station data forwarding demo "wireless adapter"
DEVICE to forward data has LAN -> connected by RJ45 to -> LAN8720 -> ESP32 as Station -> connect to a extern Wifi Hotspot Device sends continous data stream to the connected client at extern Wifi Hotspot there is no problem and all works fine
Ethernet to wifi softap data forwarding demo "WiFi hotspot"
DEVICE to forward data has LAN -> connected by RJ45 to -> LAN8720 -> ESP32 as Wifi Hotspot Device sends continous data stream to the connected client at ESP32(WifiHotspot) first 3-5 seconds all ok, then get a mess in data stream
where can you make a flush or increase or better tune the buffer i think the mistake is in the buffer ( read write forward goes to mess ) in Hotspot Mode.
any suggestion? it is a very good example - i do not want to miss it
thank you best wishes rudi
