## Field Documentation

## ◆ [struct]

struct { ... } MQTTAsync_connectData::binarypwd

The password parameter of the MQTT authentication.

Set data to NULL to remove. To change, allocate new storage with ::MQTTAsync_allocate - this will then be free later by the library.

## ◆ struct_id

char MQTTAsync_connectData::struct_id[4]

The eyecatcher for this structure.

Will be MQCD.

## ◆ struct_version

int MQTTAsync_connectData::struct_version

The version number of this structure.

Will be 0

## ◆ username

const char* MQTTAsync_connectData::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.
