I'm working on a project that have two separate setups for Arduino, each Arduino read sensors and send data to smartphone. how to connect two Arduino then send all data to smartphone over Bluetooth?

  • Do you really want to use bluetooth, or is that just a idea? Should the two Arduinos connected with each other, or just each one with the phone? If the first, should this also be wireless?

    Yes I want to use Bluetooth to connect Arduino with the smartphone, I want to use nrf24 module to connect two Arduino and send all data to the smartphone with HC-06 Bluetooth module, but I need a guide for connection and code.
