ESP-12F | Arduino IDE | Sometimes works sometimes not

Hi guys,
It's just me or sometimes after uploading a simple sketch (blink led) the code doesn't work (no boot properly) ?
I have to repeat the same procedure a couple times in order to put the code running.
Thank you in advance.
Regards,
Luiz

I don't recognize this behaviour, the only thing that occurs is that I can program one board at a faster rate than the other, but I'm hardly ever having programming or booting errors.

I have read about a lot of people complaining about ESP on breadboards.
I bought
one of this and I'm going to give it a try. I hope to get no more errors.
Thank you.

Luiz

There's no info about what type of ESP-module you use. If it's an ESP01, the breadbord you suggested might work. However, it still requires re-wiring.
If it's a different model, like ESP07, ESP08 or ESP12x, you should keep in mind, the pin-distances are not 2.54 mm, but 2.0 mm. There will be a mismatch in such case, but can be solved by connecting small wires between your module and the breadboard (as for the USB-to-UART converter).
Another thing you might keep in mind : verify if all components are well soldered at your module. On occassion I've seen loose connections at ESP-modules.
