Guys, I am trying to build a wifi weighing scale, which will transmit data to an android app and a web client.
Currently, I use a HX711 to read data from the load cell to arduino.Transmit the weight from arduino to LCD. Also, Now I need to transfer the data to the ESP8266, to initiate a transmission to the app and the web client. I am using ESP-12
I tried I2C initially with arduino master and esp8266 slave. But seems, ESP8266 doesnt support slave mode as now. In my case, its the arduino which will talk more and Hence, I need it to initiate data transmission to esp.
So, my questions are: 1) What is the best way to transfer the data from arduino whenever necessary to the esp? Will both being masters help?
2)Or is it possible for me to completely eliminate arduino, use ESP8266 alone to control the lcd, read data from HX711, also transmitt data to the android and web client?
All suggestions all welcome! Thanks in advance :)
