Before doing the tests one must define the test sites. From experience each test site takes in average 10 minutes. So, do not
plan more than 30 sites for a day else it becomes unmanageable.
Test procedure:
• Go to first site
• Set the "ID" field to 0 and "Number of packets" field to 15
• Reset the LoRaMote
• The end device led starts to blink fast at first then slower, each blink corresponds to one frame transmitted
• Take a picture of the site and write down in the log book the site position and characteristics. This is compulsory to be
able to repeat accurately the test later on at exactly the same location and also to generate the report.
