Standalone
Pressing the button for a few seconds will activate the device. The LED lights blue as
the device turns on. Then the device will execute the sequences described below.
SNT has two main options: monodirectional (uplink only) and bidirectional sequences
(uplink and downlink).
By default, SNT is set to Uplink mode.
These modes can be set by AT commands
(see next chapter).
These sequences are looped 10 times, then device shuts down automatically.
