Re: Problems with promiscuous mode (capture network traffic)

I'll ask around. Regardless of this, you may want to make your callback as minimal as possible. In an application I have (https://github.com/SHA2017-badge/bpp/blob/master/esp32-recv/main/bpp_sniffer.c) I essentially just do some quick filtering, then push it into a ringbuffer. I then have a thread r...

Re: Arduino SDK can not set IIs clock

Have you actually enabled I2S and set the clock output to a GPIO?

Re: Look out,I found so many problems with the d2wd!

Also,
Thank you! I will try it as you say, but i want to ask if we can supply the esp32 d2wd in 2.8V@200ma?


That is not going to work. We recommend at least a 500mA power supply for the ESP32 in our design guidelines.

Re: 40 MHz Crystal mandatory?

To come back to this: It seems that the issue is that our phy code from a while back (=end of 2016) had an issue where some ESP32s failed to lock their PLL when conencted to a 26MHz crystal. The end result would be that you'd have no BL/WiFi connectivity: you would see no WiFi APs and BT communicati...

Re: Problems with promiscuous mode (capture network traffic)

Run a 'make clean'; looks like the hangup of your PC corrupted some ephemeral files that are used to track dependencies. Make clean cleans them up; the next make will re-create them.

Re: Look out,I found so many problems with the d2wd!

I'm sorry that you assumed the D2WD is exactly the same as the D0WD; because the flash is connected to different internal I/O pads, that is just not true, and hence needs an up-to-date ESP-IDF. Also, my apologies for the fact that the flash tool was not updated; most developers use the internal espt...

Re: Audio Output

Yes, there is, unfortunately because of reasons it will take a while. I'm not too up-to-date with Arduino, but from what I know there's no I2S interface there yet. You may want to see if you can use the ESP-IDF driver from Arduino: docs are here http://esp-idf.readthedocs.io/en/latest/api-reference/...

Re: Is brownout detection usable now?

FWIW, the issue with the ESP32 is usually 'weirdness' (often an illegal instruction exception) on WiFi bootup; unrelated to the TCP/IP stack or the drivers itself. It's separate from the ESP8266 issue.

Re: Guru Meditation Error of type IllegalInstruction?

What hardware do you use? Weirdness on WiFi startup is 99% of the time caused by your 3.3V rail not being able to deliver enough current.
