Write some Software for raspberry Pi

Task: I have 2 raspberry pi's 1. Pi_1 acts as BLE transmitter, this will contineously transmits/ advertise itself as Beacons. 2. Pi_2 has to detect the Pi_1 automatically, if Pi_1 comes into the proximity / Range of Pi_2. 3. Once Pi_2 Detects Pi_1, Pi_2 has to compare the Beacon (UUID)data of Pi_1 with Pi_2 UUID. 4. here Pi_1 has to send some data over UUID frame, and Pi_2 has to compare it's UUID data with Pi_1. 5. if the data is similar, Pi_2 has to send the instructions to Pi_1 to glow an Green0-LED connected to it. 6. If it is not similar Pi_2 has to send the instruction to Pi_1 to glow Red- here i need 2 scenarios <Matching and Not matching conditions>
