Issues with ESP 8266 ESP-01
Posted: Tue Jan 05, 2016 1:46 am1. I have ESP8266 esp-01. I tried connecting it using usb to rs232 ttl, pl2303hx.
2. The adapter supports 3.3v , so I powered the esp VCC and CH_PD with it.
3. The TX of ESP was directly connected to the USB adapter and RX of ESP was connected using a voltage divider to TX of USB adapter.
4. As soon as the ESP was powered on the a received a ready prompt on the serial terminal window but couls not send any commands back to ESP.
5. Now the ESP has automatically has gone into AP mode. The AP has no authentication and I can connect to it using my mobile phone. I get a IP address 192.168.1.4 by DHCP. But when I try to connect via serial port I do not get any "ready" prompt on my pc, though the TX led on my ESP and RX led on my USB adapter do light up.
6. How can I reset the esp to its normal working mode and get ready prompt in serial mode.
