ESP32C3 WiFi problems

[profjmer]

ESP32 vs ESP32C3 : same samples, different results.
Do we have to do a specific configuratiion for soc esp32c3 ?
ESP32 vs ESP32C3 SMING-IDF-v5.2-beta1.pdf

IDF 5.2 is now out of Beta so you need to update your IDF installation - see #2732.

[mikee47]

For reference, you should see boot: ESP-IDF v5.2.1-sming 2nd stage bootloader and later on phy_init: phy_version 1150,7c3c08f,Jan 24 2024,17:32:21 for the current IDF sming fork release.

ok

Updated to latest, test on c3 for Basic_WiFi compiles and same problem persist. AP activated but not visible in AccessPoint list on PC

[mikee47]

Re-checked and works fine for me. This is the boot log, see how it compares:

Hmm. Looks pretty much identical. Have you tried a make flashinit then make flash ? (In case there's some internal IDF config stored somewhere messing things up.)

[profjmer]

I changed for another C3, and AP is showing OK.
Problem was a bad C3 super mini.
Thanks for your help
