[FEATURE REQUEST]ESP32 support

[luc-github]

I know it may need some esp32 core update but any chance for ESP32 support ?

[d-a-v]

There are little updates done in esp8266 arduino core to enable web hooks.
Unfortunately the PR is mixed with other internal changes.
Functionality main changes are:

• WEBSERVER_HAS_HOOK
• definitions
• declaration
• addHook()
• hook call
• example

I guess the hook call in ESP 32 arduino would have to happen there.

Do you think you could make a PR of it ?

[luc-github]

So if I implement each steps - in theory it should be ok ?
I give a try and report to you ^_^ thank you

[d-a-v]

It will be OK, no reason against it.

I forgot to mention the return type in

bool WebServer::_parseRequest(WiFiClient& client)

that must be changed to ClientFuture.

• return false => return CLIENT_MUST_STOP
• return true => return CLIENT_REQUEST_CAN_CONTINUE
• update the caller of this function to manage the return value (4 choices).

[luc-github]

ok noted - thank you 👍

[luc-github]

@d-a-v I did first part luc-github/arduino-esp32@b523379
seems working - I have followed your instructions even I have no idea of what I am doing ^_^

Testing with HelloServer.ino

/ and I got hello from esp32! in browser=>ok
/dump and no answer in browser =>ok
/yes and got proper answer

Telling server to forget this connection

Now checking WebDav code but I have realized that FS of ESP32 is different from ESP8266 so cannot be drop as it is , as well as all call related to ESP8266WebServer - I will check that part first before pushing PR to ESP32 core

[d-a-v]

The "hooked" way of using espwebdav imposes that the files on the filesystem are stored in /theHookedDirectory/.
I understand that it is currently a limitation.
Until this is improved, can you try to store files in the FS's directory /yes/ and check if you can see them in a webdav browser ?

[luc-github]

Sorry you misunderstood my test
/ is to check root
/dump is the hook
/yes was to go to not found handler so it is working as expect

So it is ok with Helloserver.ino, I have clarified my report

[luc-github]

hi here the POC luc-github@d949d6f

I have some refresh problem - but not sure how to address it

[luc-github]

OK I have followed your advice and indeed debug was part of issue
the other part was the File system difference SPIFFS esp32 is different to SPIFFS

• the file/dir detection - I use exists instead of open
• the mkdir feature - it does not work

Helloserver.ino => Ok
Simple_esp32.ino =>Ok
Hooked_esp32.ino => WebDav Not working - under investigation

[d-a-v]

the mkdir feature - it does not work

spiffs has no support for directories, but sdfs has. What FS did you try with ?
Does esp32/arduino have littlefs (it has support for directories too).

[luc-github]

yes I know, I am trying with SPIFFS - ESP32 has SPIFFS/FAT /SD not yet LITTLEFS , it is planned in 2.0 but currently it can be used as external FS - I will try it later

I also suspect the pb with the hooked is also related with directory pb, a nice to have would be to separate the url from the real directory name
for example use http://192.168.1.61/dav but map the / of the FS or /www/dav of FS not /dav

for example use http://192.168.1.61/dav but map the / of the FS or /www/dav of FS not /dav

That is a fair request

[luc-github]

still working on difference of FS
here as example the output between the 2 littleFS

The simple_esp32.ino is ok
The hooked_esp32.ino is still failing
esp8266.log
esp32.log
Esp32 do not have HTTP_HEAD neither keepAlive connection - so I think I have added them but I may still miss one part to make the connection to succeed
here the esp32 webserver modified https://github.com/luc-github/arduino-esp32/commits/webserver-hook/libraries/WebServer

I do not know what is missing 😭

[agoy507]

How wiring sdcard to esp32 ?
how configuration pin on sourcecode?
can you describe ?

[d-a-v]

SD cards have mmc emulation. It's on the SPI bus.
You need one of the SPI buses (MISO, MOSI, CLK) and another unused GPIO for CS.

thanks :D
