i've bought an ESP8266 - 01 and something with my "Chip Power Down" doesn't work as I thought it will.
I uploaded a blank sketch on my arduino uno and connected it as I listed here:
Gnd->Gnd
Vcc->3.3V (using the 5V pin from the arduino and a voltage divider; 2 resistors)
TXD->RX (Pin 0)
RXD->TX (Pin 1)
Then the red LED turns on. But if I now plung in the CH_PD to 3.3V the red LED goes off. Can someone please help me. I thought the blue LED should blink one time and the red LED is on for the whole time when it is connected to power.
I'm sorry for my bad english. I would be very thankful for every tip.
