Overview

This section shows you how to schedule messages on the Myriota Module, so they can be sent to your Destination. More examples of how you might schedule messages for different types of applications can be found in the examples directory.

In a production environment, the Myriota Module requires its location and the current time in order to operate correctly. The Module will obtain this information from GNSS satellites at start up. Within the lab environment, you may not have access to a GPS signal, and so we have provided some alternatives that allow you to progress with your development.

The following scenarios provide guidance on the appropriate tutorial section for you, depending on the nature of your lab setup:

  1. You are able to situate your Developer Toolkit outside, giving you access to both the real satellite and a GPS signal
    • You can run the Send with the Real Satellite section
    • Note that when using a satellite, you will experience normal message latency. The module will queue scheduled messages and wait for the satellite to be overhead before transmitting. Depending on the time and on your location, this latency may be up to 16 hours.
    • This can be annoying during development, and so you may want to use one of the following two options to get started quickly, before moving onto using a real satellite
  2. Your Developer Toolkit is situated inside, but you have access to a GPS signal via a GPS repeater, or by positioning your Toolkit close enough to a window with an open view
    • You can run the Send with the Satellite Simulator section
    • The Satellite Simulator requires the Myriota Module to have access to a GPS fix, but allows you to send messages without access to a real satellite.
    • Using the Satellite Simulator has the added advantage of avoiding the message latency associated with a real satellite, which is useful in development and testing
  3. Your Developer Toolkit is situated inside, and you do not have access to a GPS signal
    • You can run the Send in Lab Mode section
    • Using Lab Mode, the Myriota Module will operate without needing a GPS fix
    • Lab Mode has the added advantage of avoiding the message latency associated with a real satellite, which is useful in development and testing
