Algorithm 1 Network Probe

Input: Datarates and Payloads to be tested

Output: Perceived RSSI (Received signal strength indication) of each message

1:  initialize radio at device

2:  initialize application connected to TTN

3:  for each payload in payloads[] do

4:     for each datarate in datarates[] do

5:       set datarate

6:       send payload

7:       sleep in order to comply with the duty cycle

8:  collect RSSI values from application
