ParamRequestRead class

Request to read the onboard parameter with the param_id string id. Onboard parameters are stored as keyconst char* -> valuefloat. This allows to send a parameter to any other component (such as the GCS) without the need of previous knowledge of possible parameter names. Thus the same GCS can store different parameters for different autopilots. See also https://mavlink.io/en/services/parameter.html for a full documentation of QGroundControl and IMU code.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

mavlinkCrcExtra → int

no setter, override

mavlinkMessageId → int

no setter, override

paramId → List<char>

Onboard parameter id, terminated by NULL if the length is less than 16 human-readable chars and WITHOUT null termination (NULL) byte if the length is exactly 16 chars - applications have to provide 16+1 bytes storage if the ID is stored as string

final

paramIndex → int16_t

Parameter index. Send -1 to use the param ID field as identifier (else the param id will be ignored)

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

targetComponent → uint8_t

Component ID

final

targetSystem → uint8_t

System ID

final

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

serialize() → ByteData

override

toString() → String

A string representation of this object.
