Detailed Description

Data typically stored in retained memory or EEPROM to avoid having to fetch the name so often.

This structure is currently 44 bytes. It cannot be larger than 255 bytes because the length is stored in a uint8_t. If the structure size is changed, any previously saved data will be discarded and the name fetched again.

Also note that DEVICENAMEHELPER_MAX_NAME_LEN affects the size of this structure.
