@holgerlembke If the WiFi get disconnected from the AP the contexts that are used to handle TCP/UDP get invalidated and you need to .begin() them

@sdrsdr that's what I assumed. again, I think the examples should reflect and teach about those situations.

The point was that you can handle the situation in wifi callback and avoid the failed request altogether :)

the WiFi event callback has currently no public API for access, only a override is possible.

anybody familiar with reset timing differences between esptool.py and esptool-ck 0.4.5 ? I'm setting up a custom board (10k pullups on ch_pd & reset, 10k pulldown on gpio0), and esptool.py works great, but esptool-ck always fail. I hooked up logic analyser, there are some notable differences, but sequence of reset/rts and gpio0/dtr seem to be acceptable for both.

gpio0 needs a pullup and gpio 15 the pulldown
basically it shut look like this:

may the speed of the Serial is different, the bootloader auto detects the baud so you can simply try to lower it.
sometimes high speed serial download make problems
