ESP8266 Community Forum

- Thu Mar 19, 2015 3:00 pm #12276 Hi, I have a problem with my esp8266.
I have flashed it to v0.9.5.2.
It is connect to a USB-Serial converter with 3,3V (TX and RX have also 3,3V)

wiring:
USB to Serial => ESP8266
GND => GND
UTXD => URXD
URXD => UTXD
3,3V+ => Vcc
3,3V+ => CH_PD

Connected on COM6 / 115200Baud

When I start the connection I always get the same message in a loop. Commands like AT show only sometimes a "OK".
What can I do?

....And sorry for my bad english
