@ESP_Sprite, the changes to the 3.2 release tree were an ability to hook into the panic handler, so you could fetch info about the crash (backtrace, crash reason) in user app code. Essentially, add a function to provide a callback, and invoke that callback in the panic handler in components/esp32/pa...

Many thanks, ESP_Jack ! My ESP-IDF version is 3.2, thus esp_wifi_config_11b_rate() is not available. I am a bit hesitant to change the ESP-IDF, since I have some private patches on top of v3.2, which enable more detailed crash reporting. But if you think that v3.2 is too old and a newer version will...

Wow, this seems exactly like the tweeky type of API I'll need. Many thanks, WiFive, will try and report my findings.
I'll need to disable AMPDU first, right?

Any ideas?

ESP32-WROVER-32E based data logger is collects data during the day and uploads it via WiFi during the night. Strangely, the bulk transfer speed starts out great, but reduces greatly after a few minutes (sometimes 1 minute, sometimes 5 minutes, with 2 minutes being typical). Sample1: https://i.imgur....

Any ideas? At least why the transfer speed dropped without any interaction from my side?

I'm not a specialist, but I've used an ESP32 for audio recording (voice, stereo, 24 kHz). But I'm using an internal chip that is I2S compliant. Have you looked into ESP ADF ? It has a lot of examples and links to development boards which have all the needed hardware. You may be able to answer your q...

Hi, I'm having issues with slow and inconsistent transfer speed, transmitting from an ESP32-WROVER-32D to a PC through a WiFi AP. The changes in speed are somewhat random, and while initially it starts as not-so-bad (1.6-2MBit or 200-250kbytes/sec), it works like this for a minute or two, then drops...

Any ideas?

Sorry, I guess I'm not helping much here (answering a 9-month old question). The root cause was never found out, but my best guess is that the high EMI noise near the ICE was the culprit and it was causing the flash chips (Winbond W25Qxxx) to execute something stupid, like to partly erase a block of...
