Re: ESP32-P4 eval board: Sleep with low power, but keep touch (of screen) active

Thanks chegewara, I didn't know that! I'm still a bit at sea: What happens, when I send the ESP32-p4 to light (or better deep) sleep with the GT911? Does it get a sleep command (i.e. variant d sleep mode) as well and needs to be waken up sperately again before I can use its int-pin to trigger a wake...

ESP32-P4 eval board: Sleep with low power, but keep touch (of screen) active

Hi there, I've managed so far to program an SSE client with lvgl ui, which works fine, but draws ca. 780 mA of current from a 5V source. I'd like to realize a power save mode for this, meaning the screen is dark, all peripherals are powered down _except_ the touch function of the screen, i.e. the in...

Re: Implementation of Server-Sent Events (SSE) in ESP-IDF

@Microcontroller Many thanks a lot for your help! However, I don't get it working (with Arduino IDE I had no problems with SSE). The html site is transferred and executed, the /events URI gets called, and the browser receives an OK 200. But then nothings else works - the ESP32-S3 keeps sending 127 c...

Re: Implementation of Server-Sent Events (SSE) in ESP-IDF

I've tried that now. My html code is this, and I have to stick with this (EventSource). <!DOCTYPE HTML> <html> <header> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <title>Eventserver</title> </header> <body> <hr> <h1> Test Async Event Source</h1> <br> <p>Complete State: <span...

Re: Implementation of Server-Sent Events (SSE) in ESP-IDF

I'd like to second this question! What I've found so far is only this: https://esp32.com/viewtopic.php?p=115818 https://esp32.com/viewtopic.php?t=24445#p87263 And maybe also this could help: https://esp32.com/viewtopic.php?t=24445#p87180 But for me that has been not sufficient to achieve anything fu...
