E2ES States

E2ES may be in one of three states:

Idle Started Silenced

In the Idle state, no data is being logged and there is no radio activity. The only way to remove

the E2ES from Idle is to manually push the button.

In the Started state, data is being logged in the circular buﬀer and the Radio is functioning. The

only way to stop the E2ES from logging is to issue the Halt command.

In the Silenced state, data is being logged in the circular buﬀer and there is no radio activity.

The only way to go back to Started state is to manually push the button OR the E2ES will revert

to the logging state after X seconds (set when entering Silenced state).
