Limits the maximum stat group name length in mcumgr requests, in bytes. A buffer of this size gets allocated on the stack during handling of all stat read commands. If a stat group’s name exceeds this limit, it will be impossible to retrieve its values with a stat show command.

Direct dependencies¶

MCUMGR_CMD_STAT_MGMT && MCUMGR

(Includes any dependencies from if’s and menus.)
