Is there a way to send data from one seeeduino to another one so it can be used by its program?
There are many ways to connect two Arduinos. You can try the I2C communiction. Connect with a grove cable the I2C ports and use the scripts.
Serial or I2C are the normal ways to do it. There are others ways but these are easiest.
Serial is easier to code and is faster as it is duplex communication.
Wiring example with code can be found here: http://www.martyncurrey.com/arduino-serial-part-3-getting-started-with-serial-communication/
The example uses an Arduino Nano but just hook up the same pins. Tx on one Arduino to RX on the other Arduino.
Also note that if the TX/RX pins are wired up you CANNOT UPLOAD CODE as it uses those pins to do so. Disconnect the wires before uploading code.
