I connected all the pins as in datasheet, except ch_pd. But when I connect ch_pd to 3.3 V , the red light on esp8266 goes dim. I used 3.3 V, 250 mA power supply. What is the reason for this?

  • Link to datasheet? Link to ESP8266 device used? Image of how you have wired it up? Commented Sep 24, 2016 at 14:34
  • Recommended power supply sourcing capabilities are about 1A. In the firmware upgrading mode WiFi is possibly disabled, so it needs much less power. Commented Sep 25, 2016 at 6:17
