Re: Esp32 and wifi laboratory test.

Are you using the esp-idf or the Arduino IDE? If I understand correctly, seems like you should be able to slightly modify the standard Arduino IDE example such as https://github.com/espressif/arduino-esp32/blob/master/libraries/WiFi/examples/WiFiClientBasic/WiFiClientBasic.ino to output whatever seq...

WiFi disconnect before getting IP address

I have 2 systems running the same code - one works well, the other doesn't. In the working system, WiFi connectivity is no problem - In my logs I see: [2020-04-02T00:07:24.360] W (25242325) WIFI: waiting for Wifi connection to SolSense [sys 0] status=1 - try 21 [2020-04-02T00:07:25.346] I (25243317)...

It seems that the 3.3 firmware does something that causes the problem when I reload programs created with 3.0 firmware. erase_flash fixes the issue but obviously not a vi...

Unfortunately don't have anything definitive from the customer yet but I have now also seen this w/o the mess in a test fixture. What causes these resets?

Re: TG0WDT_SYS_RESET and TG1WDT_SYS_RESET

Thanks - I enabled brownout detection yesterday and noticed a few instances where it triggered. I've asked customer to instrument supply quality to check. Will post results if that was the issue.

TG0WDT_SYS_RESET and TG1WDT_SYS_RESET

Hi, I am running freertos on 2 cpus - at one customer site I see occasional errors such as the following, sometimes with TG0 and sometimes with TG1, and every so often the board even locks up (but that's w/o any errors whatsoever). The stack pointer printed often points to a "Double Exception". I wa...
