Hello, I really appreciate this great project. I already got some experimental lights running on a Wemos D1. Now I wanted to upload WLED via the web installer to a ESP8266 07 / 07s due to the possibility to have a langer Wifi range with an external antenna. The flashing work both ways (once over an own build setup, once over an programmer socket) until it reaches nearly 100%. Than the error “Timed out waiting for packet header” is shown. I already searched online, but eg the hint with additional capacitor between EN and GND did not work for me
Hello , You did not mention if you can flash in Ardunio IDE and if so them below might not apply .
I haven’t used that specific programmer nor chip but used others including esp01s and 2m and 4m esp8266s as well as some esp32s . For my own testing you may (or may not) need to keep gpio 0 connected to GND and some of the MCUs only worked by flashing the corresponding bins from this site https://wled-install.github.io/ but did not work from the normal wled web installer here https://install.wled.me .
This is from my own testing on a PC and a mac but with a lot of different units . Cheers
thanks for your message. I am not using Arduino IDE but I tried to flash again with the WLED web installer and added a jumper wire between GPIO0 and GND, but same problem as above.
I am aware you are not using Arduino IDE . However as the question is related to flashing that module in general and not specially WLED I assumed you have tested in Arduino IDE first to see if there is a way to flash then test WLED after .
In my case some of the MCUs behaved differently when flashing and we had to do trial and error but most worked from this web installer https://wled-install.github.io/ . If you have a lot of MCUs then i assume you can also try that route of trial and error . I wish you luck as you may need to google how to flash that module with that burner and hopefully find a way .
Maybe the esp is not making a good connection? That is a weird board. I see that the esp is not soldered but just press fit into a weird socket thing. The only reason I could see using that board in the first place would be to flash a bunch of esp’s to later solder to other projects.
Ah gotcha. Well still try taking the chip out and putting it back in the socket and don’t move it around while it’s trying to flash. Still could be a simple bad connection. Good Luck.
