HI,
wireless Sound Meter
This is my sound sensor code. Function of my project is sense the sound value and convert analog to digital , after conversion i send the digital data of sound in dB to android via bluetooth HC-05 and OLED 0.96''. But i need to store sound data in specific location arduino like i want to use only my apk with arduino, Like i want specify where the sensor data available.
for example in Ruuvi sensor , there is multiple parameters are measured and transferred to android via Bluetooth. They specify each parameters in HEX address in both android and microcontroller like for temperature value -127c - 127c from 0x04 to 0x17, like the same i want to allocate specific loaction for my data 0dB to 128dB . PLEASE HEPL ME WITH YOUR IDEA

This is an Arduino forum... Are you using an Arduino?

yes i'm arduino

You need to explain better what you are trying to do. I honestly have no idea.

Hello gajm07
Take some time and describe the desired function of the sketch in simple words and this very simple.
Have a nice day and enjoy coding in C++.

Sorry , i updated details now
