Can't send data to ESP8266 module
Posted: Sat Apr 02, 2016 4:03 pmHi all,
New in this community and got a a problem : I can't upload arduino sketch to ESP module.
ESP is in flash mode but I got "
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed"errors
My esp module is powered with 3.3v breadboard power supply (not usb/serial module).
Usb/serial and esp8266 have the same ground.
While uploading I see transmit led blinking on converter but not on ESP....
I tried with other wire : no change !
Another pb : I can't use arduino serial monitor to sent AT commands : nothing seems to be received ... ( led blink while sending but no response)
on the other hand I can send AT command using arduino board directly (serial communication).
Do you have any clues ? Do you think I may buy new modules (eg usb to serial converter) to try again? or is there any config I may have missed.
Many thks in advance.
