Hello everyone,

I have a esp8266-01s that I want to flash.
I have already tried this by following tutorials on sites, but they didn't help.
Only 1 time i was able to flash the module, but after that it wasn't showing any thing on the serial monitor.
Even when i have the right baud rate.

Could someone help me please?

Hi, I have also suffered a lot of issues with flashing that model of ESP. For me following this tutorial solved the problem (besides that i had to connect RX and TX pins without a voltage divider, which is not recommended since the ESP is not 5V tolerant, but it was the only thing that worked for me.) https://www.youtube.com/watch?v=P_ecAFpUADU&t=5s In my case i used arduino uno, but perhaps this could help you.

It is a good idea to buy a USB-TTL adapter instead of using an Arduino Uno.

For the ESP8266, I particularly like the adapters that use the CP2102 chip because it is 3.3V on its TX and RX pins such as this one sold on eBay https://www.ebay.com/itm/CP2102-USB-2-0-to-UART-TTL-5PIN-Module-Serial-Converter-Adapter-Red-Silver-TS/382799096448
