I have a custom design with ESP32. My GPIO0 is held LOW, my EN pin is connected to 3.3v. When I boot, I get the “waiting for download” prompt. However, I always get the famous “Timed out waiting for packet header” error. Any help is appreciated Reply Sara Santos November 24,...

I added a 100µf cap to the 5v power plane, next to the 5v pin of the ESP32. The system now boots. I believe this will solve the issue. Adding a cap next to the EN pin, just in case. Laying out the new PCB at this moment. Many thanks, Davidepsilon...

其次就是它的ble也挺有趣的，可以自己做鼠标或者键盘。这是前段时间自己做的，题主可以参考一下。
Thanks for this code works fine in my ESP 32 Dev Module. However I tried using the code in an RGB using “ledcAttachChannel(ledPin, freq, resolution, 0);” controlled by a PS3 controller. However compiler does’nt agree with it, getting an error message below, C:\Users\Admin\Documents...
