## ◆ struct_id

char struct_id[4]

The eyecatcher for this structure. Will be MQCD.

## ◆ struct_version

## ◆ username

const char* username

MQTT servers that support the MQTT v3.1 protocol provide authentication and authorisation by user name and password. This is the user name parameter. Set data to NULL to remove. To change, allocate new storage with ::MQTTAsync_allocate - this will then be free later by the library.
