#69950 I am using esp8266-01 connect to arduino uno. I try the example WiFiScan of Esp8266WiFi.
I connect like this:
ESP 8266 Arduino
RX -> RX
TX -> TX
VCC, CH_PD -> 3.3V
GND, GPIO 0 -> GND
It work perfectly. However i read in some posts that say connect Rx of esp8266 to Tx of Arduino and Tx of esp8266 to Rx of Arduino, I try it but got the error like that error: espcomm_open failed, espcomm_upload_mem failed. Then i put the voltage divider between Rx of esp8266 and Tx of arduino(i wire as the image dht11.jpg below). I still got the same error. Can you help me to fix that problem. Thank in advance!!
