My whole ESP experience is ( we assembled a lot more than 5000pcs of this module up to now), that this kind of problems are mostly related to improper PCB Layout (Pullups, Powersupply, decoupling ...) or due to some specific pins, that are not that fine for this high speed signals (like the GPIO0 on...

From reading this topic, no: Your problem is that the ESP does not generate a valid MCLK signal itself. But in my case the ESP32 was not capable to synchronize to an EXTERNAL provide MCLK Signal. And it seems that the S3 Version now can. I wanted to double check this from an espresso Hardware guy to...

Long time ago. We realized this issue with a (in fact expensive) sample rate converter IC due to the fact that there was no solution to that issue. But what I discovered now is that with the SOC_I2S_HW_VERSION_2 Capability it seems that the ESP is able to sync to external MCLK. This seems to be poss...

Yes, thanks, I try to optimize this workaround. What I do not understand is, that the httpd_queue_work() function is nearly always returning ESP_OK even if there is no remote available any more. My assumption was that the callback will be called somewhen even if the remote is lost on this socket.(th...

The problem ist that this function (httpd_ws_send_frame_async) is never called any longer because it is inside the callback function ws_async_send() that is never called any longer once the connection is broken

Hello, We have an ethernet device based on ESP32. So no Wifi, but I do not think it is related to Ethernet or Wifi frontend. Using ADF2.5 (and IDF4.4.4) I am struggling with a problem concerning open WebSocket connections. We have a listener that holds open Websocket connections to control the ESP v...

Yes, everything fixed, thanks a lot

Thanks for this quick reply. I knew that it must be a stupid issue, but that stupid...
I will fix this and check if it is working then.

Hello, I am up to now using more than a few thousand WROOM32 and WROVER32 modules so far and now I am struggling with a simple problem, but I can not find the issue up to now in my hardware design. The problem is simple: -> Flashing the unchanged hello_world example to a custom ESP32 PICO V3 board w...

I have the similar issue, still nobody an idea?
