The maximum size of the response to the info command, will use a stack buffer of this
|
||||
size to store the data in. If the output response is too big then the output will not be
|

present in the response, which will just contain the result code (rc) of memory error.

Supports adding custom command/character processing to the info command by using

registered callbacks. Data can be appended to the struct provided in the callback.

help
|

Will allow returning the build date and time of the firmware by using the info with
|
||||
format option 'b' (will also be returned with all responses by using 'a').
|
||||
|
||||
Note: This will invalidate reproducible builds of the firmware as it will embed the
|
||||
build date/time in the output firmware image.
