4.3.1 Get Status

Table 4-3 lists the Get Status command.

Table 4-3 Get Status
Description
BriefThis command returns the status of the last command executed.
Typically, this command must be invoked after every command sent to ensure that the previous command was successful or, if unsuccessful, to properly respond upon failure.
The bootloader responds by sending a 1-byte packet containing the current status code.
