Unable to connect to WiFi

[steveh]

Running on a Tulip CC with unmodified tulip-firmware-TULIP4_R11.bin.

Attempting to connect to a random neighbours network (with the wrong password) returns an empty prompt after a second or two.

>>> tulip.wifi('neighbours-wifi', 'wrong-password')

Connecting to my wifi, with the right password or the wrong password, crashes the system.

My guess is that something about my WiFi is not implemented in TulipCC. WPA3 perhaps. I worked around it by resetting my network settings back to their automatic values. FWIW it works with an ESP8266 on ESPHome.

For reference, here's how my Unifi UDM-SE and AP was configured:

Hi! I checked out these errors and i'm afraid i don't know how i can help just yet. I haven't seen Failed to allocate AES interrupt reported anywhere else online and am not sure where it's coming from. We do support WPA3, I believe (it's turned on in the chip support settings). I'd love to help figure this out, so will try to investigate a bit more in the esp-idf source to see what that error can mean.

[steveh]

I think it's coming from here: https://github.com/espressif/esp-idf/blob/d3be7bda056dfcb7edbac4cf8757ec1ac7d0a1ea/components/mbedtls/port/aes/dma/esp_aes.c#L187

But it looks like there's been a lot of activity in that repo since, that line was rewritten in https://github.com/espressif/esp-idf/commit/2abb656ba2d14720ca7c22c636244cd9351b4643#diff-83729b211ef1fb0aad2272032878f600a9990a2288f9d83f470141990db88bdc

[bwhitman]

OK, I think the next step is to wait for #315 , and hope they've made some bug fixes to support your wifi setup .

I ran into the same problem and played around a bit - WPA3 and WPA2/WPA3 networks don't seem to work. Trying to connect to them with a correct password will crash the device. Changed to WPA2 and it did work without problems.

[bwhitman]

OK, thanks for the update. Let's hope that the later ESP-IDFs fix this issue, we'll be upgrading those soon.

[bwhitman]

We think we've added WPA3 support in the latest Tulip firmware. If you can connect to something to get it to do tulip.upgrade(), or flash it manually, let me know how it goes!
