- Fri Jun 05, 2015 6:59 am #19552 Hi,

just checking... Have you :

- Do you have a good 3.3V input to VCC?
- CH_PD pin to VCC.
- GPIO15 to GND .
- GPIO2 to VCC .
- GPIO0 to GND.

After pulling down GPIO0 you should either reset the module or pull down CH_PD to enter bootloading mode.

Also check RX-TX connections to make sure they´re right: RX from ESP -> TX of PC, and vice versa.
Have you grounded the serial port as well?

Let me know if this helps.

greetings
