Upload sketch error #29

Closed pbravoz2 closed 3 years ago

pbravoz2 commented 3 years ago

Hi there, can anybody help me for this issue??: uploading the sketch to T-Beam throws me the classic ESP32 error: Failed to connect to ESP32: Timed out waiting for packet header. The solution for the other ESP32 boards is to place a 10uF capacitor between the EN PIN and GND. But T-Beam doesn't have the EN pin! How can I solve it?. My T-Beam version is 1.0

I am very thankfull for your help. Greetings, Pedro

You can try it like this, IO0 is shorted to GND, then press reset, then click upload

Hi lewisxhe, it works perfect. The order is:

-IO0 shorted to GND -reset (it boots in a special mode waiting for upload) -upload the sketch -disconnect IO0 from GND -reset to normal boot

Thank you!!
