Hi @matty_t We recently ran in the exact same issue with a custom PCB with an ESP32 and custom Antenna. Hi @memory_stick! Glad to see I'm not the only one with this issue, but not glad that we are both having this issue x) long story short: With our design it was the crystal Oscillator, more precis...

Looks like some issue impacting WiFi reception/transmission... from what I experienced, every step in the WiFi association has a timeout for the other party to respond. If the packet gets lost somehow/somewhere, no response comes, and the association will restart from scratch. Aha! It does seem to ...

Have you tested for shorts on the antenna trace to all power planes and surrounding pins? If nothing obvious is wrong the best option is probably to assemble another board. I have, no shorts RIP. I do have some interesting new evidence though, and thorough dives into the code haven't given me much,...

Yeah, 9V batteries generally have a very poor internal resistance; it would certainly not be my first choice to run an ESP32 off. However, if that were an actual issue, I'd expect the ESP32 to brown out. Still, connecting something else to it (lab PSU? USB power bank?) could give some insight. Few ...

Yeah I haven't been able to get my hands on a good power supply until tomorrow so will give a go. But yeah, I agree that I would have expected the ESP32 to brownout if the power supply was the problem... we shall see tomorrow! - Have you tried connecting to an existing (non-ESP32) access point? Yes,...

Share your schematic. Often suspect the power supply with wifi issues, it is the highest power draw function. power_supply.PNG Above is the power supply I used for the board. Its the MAX17243ETPB. It has a 3A limit, so should be well within the specs of my board, since the ESP while TXing is the la...

Crystal oscillator circuit, check frequency stability

Thanks for the idea. Checked the crystal in a scope at its sitting nicely at 39.998MHz, so seems good

Hello everyone, I have a custom PCB I've designed that makes use of an ESP32 as both the MCU and a WiFi chip. Am currently trying to get it to connect to an ESP32 WROOM dev kit via WiFi, and I've tried a lot of different configurations with no luck. I'm asking for a rubber ducky to bounce my tests o...
