Hello everyone, it's been two weeks with hard work, searching the net, trying, head scratching, retrying, fraustration...ETC.
Probably you know how it feels whith ESP8266 bare bones (esp-01/esp-06...etc)
The problem: Cannot upload sketch, flash, nor update firmware to ESP-01; not with arduino (uno), nor with usb to ttl (pl2303 YP-01).
note: It worked once, I was able to update AI Thinker firmware, and uploaded a simple LED blink sketch to GPIO2 with Arduino Uno. never been able to upload since.
PS: I aslo changed the ESP-01 baudrate to (9600), because I read somewhere that the UNO cannot handle the Baudrate Speed of ESP, and it may have an overflow, so I did it with (AT+UART_DEF =9600 ,8,1,0,) command throug serial monitor and Arduino Uno, since I didn't have an FTDI at that time.
I tried the same procedures again, but nothing, so i decided to buy an FTDI(PL2303 YP-01)
After installing the driver and wiring everything, the Serial monitor shows only gibberish with every baude rate I try
I aslo noticed that the Baude rate 74880 does show the Flashing mode when, nor the error, but again gibberish, but when I plug the ESP with Arduino Uno, it shows the flash mode if GPIO0 is pulled LOW, and error if not attached, which is the normal.
Soooo, What's the deal here, is something wrong with my ESP? or is it the FTDI? or maybe I broke it when I changed the default baudrate of the ESP?
PS: I used voltage regulator with ESP
I also used voltage regulator with RX pin by using to resistors( 1K and 2,2K)
I pushbuttons with both GPIO0 and RESET, and 10K resisors with CH_PD, Reset,GPIO0.
PS: My LED blink sketch is still working with GPIO2 , and the network WIFI is showing the ESP acces point
HELP PLEASE,,, I don't care about the ESP,,, I just wanna solve the problem,,,you know how it feels when u can't solve a puzzle! So itchy
