Re: Unicast / Multicast as Unicast

Hmm, that is a valid point. Perhaps we should add at least a hint to this to the docs.

Re: Debugging Issue on WROVER and Eclipse

Error: JTAG scan chain interrogation failed: all ones FWIW: This means a physical problem in the communication between the JTAG adapter you have and the ESP32. As Kostas already said, checking your connections (as well as Vtar, if your JTAG board needs it) and seeing if your ESP32 program reconfigu...

Re: Unicast / Multicast as Unicast

You don't specify a protocol, I assume you mean USP uni/multicast? If so, ESP-IDF implements the largest part of the BSD socket specification, and unicast works perfectly through that. Just throw 'C UDP server example' into Google and chances are very high that the code you find works on the ESP32 w...

Re: EVK-NINA-W10 JTAG Debugger issue

Code: Select all

Error: JTAG scan chain interrogation failed: all ones


This usually indicates a connection problem between the jtag-interface and the ESP32. It can also occur if you reconfigure the GPIOs used for JTAG for something else in your program.

Re: How many volts can feed esp32s

I'd say none of the above. 5.4V most certainly is too much for the ESP32 that is directly connected to the 3.3V line of the ESP32. From what I remember, boards like these usually use the AMS1117-3.3, which has a dropout voltage of 1.1V, so it needs 4.4V at minimum to regulate its output voltage. If ...

Re: New wrover module (8MB psram)

There will be an option to use part of the 4MiB mappable address range to bank-switch the remaining memory in. Afaik it hasn't made it into esp-idf yet, though.

Re: ESP32 Sound output to Amplifier?

So, do you want to have a headphone output, a speaker output or both? If you want the first, just add a linear headphone amp, e.g. based on the LM386. If you want speaker outputs, just take any random class-D chip and add it on. If you want both... as you said, class-D amps usually are bridged, and ...

Re: Quickest possible digital output

Sorry, all useful peripherals for this are tied to the 80MHz APB bus speed. I highly doubt it's possible to get higher speeds than that with the ESP32 alone.

Re: aws cert storage location

For an easy solution: you can make a FAT or SPIFFS partition in internal flash and store the cert there.

Re: Which is the Best Operating System for ESP 32

FWIW: Someone can probably fill in this table, but as it takes a lot of research to figure this out for every OS out there, I'm not sure someone is just going to do this work for you. How about reading up on some of these SDKs and trying to fill in some details yourself? Also, I'm not sure how usefu...
