Re: I2S MCLK_PIN signal error?

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...

Re: I2S Slave mode with external MCLK

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...

Re: I2S Slave mode with external MCLK

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...

Re: httpd_queue_work() - memory leak when client fails

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...

Re: httpd_queue_work() - memory leak when client fails

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

httpd_queue_work() - memory leak when client fails

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...

The problem is simple: -> Flashing the unchanged hello_world example to a custom ESP32 PICO V3 board w...
