Page 37/49
0x35 – SET_UPDATE_MODE
Description:
This command enables or disables the different types of update modes. All update modes
can be enabled simultaneously.
This command is a general enable for all PIDs configured for a particular update mode.
For example, if a SET_UPDATE_MODE command is sent to enable time based
updating, all parameters configured for time based updating will be enabled and data will
start to be transmitted at the user selected intervals.
This configuration data will NOT be saved to non-volatile memory and must be set in
order to receive update messages. “As Requested” update mode does not require the
SET_UPDATE_MODE message to be sent before parameters can be requested.
