v3.0 to v3.1 migration guide? WiFi not working...

[meowsqueak]

FWIW, I've seen no issues whatsoever with Wifi. I'm always working against the tip of master so I've seen all the versions on my device and I do many, many, soft-resets while developing against my Wrover module.

Are you all sure that it is not something external affecting your wifi-connection?

Well, if I switch back to v3.0, make clean and recompile, it behaves fine. But when I compile against 3.1 and hit reset a few times, the WiFi becomes unreliable to the point of complete failure, and only a power cycle brings it back. I'm not changing anything else, certainly nothing external.

I've also noticed a third state - one where the WIFi connects, but the throughput is very slow - maybe a tenth of what it normally should be.

As mentioned above, I'll gather more info and put together a proper GitHub issue.

Please update IDF branch release/v3.1. The commit ID of the bugfix is ef2bf2386255514ff0d2bc1b30b638251fd769dd. Please check whether it works for you.

I've rebuilt and flashed my app using espressif/esp-idf commit 57118e2f10a79af0627ed56d42d24584cd4033d8 (which includes that one) and it has not resolved my WiFi problem. In fact now it won't even connect after a power cycle, so it seems even more broken than before - i.e. completely broken as far as WiFi goes.

This is why I'm wondering if there is a code change I need to make since upgrading from v3.0 - perhaps I'm missing something? My code is here (may need to disable a bunch of peripheral-specific functions in the main function to get it to run without crashing).

An odd observation - I am powering my ESP32 devkit (DOIT) via an external 5V power supply, and I am also using a USB cable to view the monitor console. I've discovered that when the USB cable is connected, the WiFi RSL reports as zero and the device is unable to connect via WiFi. But if I disconnect the USB cable the WiFi RSL shows about -91 (viewed on an LCD display) and WiFi connects successfully. I'm not sure what the explanation is for this, but I'll try alternative boards and cables in case it's a hardware issue.

I'm going to create a GitHub issue for this, but as a final comment for now:

I've tried a couple of ESP32 boards (DOIT boards) and both show the exact same behaviour. With v3.0 of the ESP-IDF, I can happily flash and reset the boards multiple times, and the WiFi comes up very quickly and without error or fault, with or without a USB cable attached.

With v3.1, I can only get reliable WiFi if the USB cable is left unattached. Sometimes, if attached, it will come up after a power cycle, but it will not connect after a reset, and if left for a few minutes it drops out and tries to reconnect. About the only thing I can do to get a persistent connection is to leave the USB cable entirely disconnected, which makes it very difficult to develop on.

I have tried different USB cables too.

So it seems to be the change from v3.0 to v3.1 that has broken WiFi for me on these boards.

new adventure. When connected to the iPhone code hangs on meditation guru. With Android clients everything works. I did not expect such instability from ESP in terms of WiFi connection. Little by little my project will be to change to another chip, but I think the strawberry Pi. I think to try whether IDF 3.1.3 or still something will fall off in this poor processor

I will remind you I did not receive the ip address of the device with Android and I installed commit . After that, everything worked with Android, but IOS a tested only now. At the same time when you connect with Android still works, there is no meditation guru. The watchdog is set for 10 seconds and can not work for 1 second, but something goes wrong.What other surprises are coming to life?

No offense brp80000 but you've already hijacked this thread once - please don't do it again.

Can you please create another thread for your own issue? Your symptoms are unrelated to mine and it's just confusing the issue I'm trying to pin down.

[littlesky]

Please create a GitHub issue for this. Someone else will help you.
