My ESP is connected to wifi and Internet acces, oll ok.

It sounds like you may be running into an issue with the IDF memory fragmentation (this usually manifests as an issue with SSL buffers).

Which module do you have on the dev kit board? Is it a WROOM or WROVER? (It should be one of the ones from the list at https://docs.espressif.com/projects/esp ... vkitc.html)

To address this, probably my first suggestion is to try using the v1.11 firmware -- esp32-idf3-20190529-v1.11.bin

If your module is a WROVER (not WROOM), then try using the GENERIC-SPIRAM firmware instead (any version).

Hello,

I think I am making a mistake. Picoweb does not seem to work with Micropython. You have to use Pycopy. But the concern is that I don't see a doc explaining how to use pycopy with an IDE, and which IDE? and then how to flash the card and upload a program in python in the ESP32 as is very easily possible with thonny and picropython. If you have an idea.
Thank you.

One way to get Picoweb running is to manually create a picoweb directory on the filesystem (uos.mkdir('picoweb')), copy or use urequests to pull the sources in to that directory. Go to the github repo and pull the latest from master. You may want to upip install micropython-pkg_resources and micropython-ulogging. Or go through the picoweb resources and remove all the code that requires those modules.

Hello,

thanks, but how to copy or use urequests to pull the sources in to that directory. Go to the github repo and pull the latest from master.
could you be very precise and give me the comment to write in repl.
thanks

So upip.install('picoweb') doesn't works?

[julien]

I managed to create the folder and change the directory to picoweb. But how to copy the files into the folder picoweb?
Thanks
