Also, is there any way to show bssid the ESP32 is connected to? Thanks.

I have this really weird issue that if I have multiple APs sharing the same SSID and password to expand my WiFi coverage, then connect() will always prefer a certain AP even if the reception is horrible. I wonder if there is any default settings when multiple devices broadcast the same SSID, which t...

According to ESP32-wrover-e doc, GPIO2 is a strapping pin with a default pull-down resistor. And if its value is LOW together with a LOW GPIO0, then program download commences. Is this correct? From my design experience with ESP32, I only have to connect GPIO0 and RESET to CP2102 in an XOR-style tra...

I am pretty experienced with ESP-IDF at least between 2019 and 2022 and then moved on to micropython development on ESP32. I know what I'm doing but not with this symptom: It's a board I designed and personally populated and tested previously to success. After sending it to a user and getting it bac...

I'm looking at the esp32-pico-D4/V3 system on a chip solution as an alternative to the ESP32-WROVER modules. I know picos don't have SPIRAM but I can add that easily. What I've found so far is that WROVER integrates both QSPI FLASH and QSPI RAM so the bandwidth would be the highest. I'm reading pico...

I still see a 'Download PDF' link at the bottom right of the document at the URL you linked, and that link seems to work.

Thank you! I wasn't aware the link was at the bottom of the page! I thought they were on the left side.

Now it seems I can't find .pdf download of the ESP-IDF API guide anymore:

https://docs.espressif.com/projects/esp ... index.html

It's quite inconvenient to read this long document in a browser. I'd prefer .pdf file. Is there still any way to download?

Thanks for sharing. I didn't check stock of LAN8720A. I guess that's another reason to not use it, besides having to rig some mechanism on GPIO0 for uploading. I'm using micropython so my support is very limited, either the LAN8720A (and a few other PHY chips I can look for stock) or wiznet W5500, w...

OK thanks. GPIO0 has CLK_OUT1 feature. I'll do some tests once I have WROOM+LAN8720A dev boards in hand. Does the trace have to have some impedance matching due to 50MHz frequency?

I'm trying to put together a design with WROVER and LAN8720A. Based on existing designs such as the one with WROOM and LAN8720A, GPIO17 is used as EMAC_CLK_OUT. I wonder if there are any alternative pins for EMAC_CLK_OUT. Since WROVER uses GPIO17 for SPIRAM, if I can't use a different pin, then I'm ...
