i would like to know How to send sensors data to ios/android app from edison to the app through ble or wifi(mqtt)?
I believe good way for you to start is on Intel® Edison Bluetooth® User Guide or Intel® Edison Wi-Fi User Guide. In those documents you will find not only the information about BLE or MQTT but on different ways the Edison is capable to interact with Wi-Fi and Bluetooth devices. Also, I'd suggest you to take a look at Building and running Mosquitto MQTT on Intel Edison believe that document is exactly what you are looking for.
