to measure rssi received by the smartphone. I am confuse about the wiring
between esp 8266 module 01 and arduino.
I found there is source of wiring diagram
Esp8266. Arduino
Vcc. 3.3V
GND. GND
EN. 3.3V
TX. RX
RX. TX
But I failed to get rssi.
There is not compilation error but warning of
Espcomm_sync failed and error of espcomm_open fail , espcomm_upload fail.
Wish some body can give me a guideline.
