@fly135 that's what I notice on the other plants, only few ms of ping. Regarding the WiFi environment: most of the (identical software and hardware) devices are installed in shielded distribution boxes alongside with the WiFi router. This is also why the RSSI is very strong. There are now other WiFi...

As this is still an issue for us I'd love if anyone could shed some light on how we can resolve this issue. I've set up on more crude test: I've connected the ESP32 to the WiFi-AP and a Raspberry PI to the same router via LAN. On the raspberry I have reasonable good connection and use it to establis...

Hello! We are working on a product (custom PCB, plain ESP32 IC) which does data logging in some remote electrical cabinets. At some facilities we noticed very poor connection quality (ESP32 takes long to obtain IP, HTTP(S) requests timeout etc., sometimes connection fails altogether) despite having ...

Thank you for your replies so far! Root CA validation has not been an issue so far for us performance-wise. The problem is: for some of our services we cannot guarantee that server or root CA might change. (such as you don't do that also when you browse normal web pages) One additional thought: when...

Use case: when I access a HTTPS site from my browser on my windows machine, I have a selection of trusted root certs and the remotes cert is validated automatically against these trusted certs. However in the ESP32 HTTPS examples it works differently: I have to provide upfront the correct server cer...

Angus, thanks for the information so far! We implemented now the 40 MHz TCXO on our prototype. It is always on (since it's not a battery powered application). For 32k we still use a simple 10 ppm external crystal. Everything is running fine so far. One additional question though: With the ECS-TXO-25...

This concerns a topic we have been discussing internally for a while. Imagine you have hundreds of devices deployed in a remote place that can only be accessed by a technician about once per year. A few devices are available for local testing, some are installed in facilities that can be accessed wi...

Since we are right now evaluating different options for our production. Basically we are looking for 8MB, 80MHz, 3.3V and QIO support. But we found that the market and the flash-support by ESP32 is a little bit non-obvious. Many chips are shown as EOL on Mouser or Digikey. It would really help if th...

I have seen something similar when I share a project between Windows and Linux. Some things are compiled/linked differently. The solution in my case is to delete the build directory every time I switch the system. Could you maybe try that?

FYI, since this bug looks quite serious to us (it prevents unattended operation of the device basically) I've created an issue on github:
