R2026b

Set microservice retry count

Since R2026b

Syntax

setRetry(microservice,retryCount)

Description

setRetry(microservice,retryCount) sets the retry count of the microservice object. The retry count controls how many times the microservice resends a message after a timeout before declaring the operation failed.

Examples

Specify Timeout and Retry Values of Mission Microservice

Create a mavlinkdialect object using the common.xml file.

dialect = mavlinkdialect("common.xml");

Create a local MAVLink client by using the mavlinkio object.

gcs = mavlinkio(dialect);

Create a mission microservice object.

mission = mavlinkmicroservice(gcs,"mission");

Set the timeout value of the mission microservice object to 5 seconds.

setTimeout(mission,5)

Set the retry count of the mission microservice object to 7.

setRetry(mission,7)

Input Arguments

microservice — Microservice object

parameterMicroservice object | commandMicroservice object | missionMicroservice object | ftpMicroservice object

Microservice object, specified as one of these microservice objects:

• parameterMicroservice

• commandMicroservice

• missionMicroservice

• ftpMicroservice

retryCount — Retry count of microservice object

nonnegative integer

Retry count of the microservice object, specified as a nonnegative integer. When the microservice sends a message that requires an acknowledgment, the microservice starts a countdown timer. If the expected response does not arrive before the timer expires, the microservice assumes the network lost the original request or the response in transit, and resends the message. This resend cycle repeats up to retryCount times. If the microservice exhausts all retries without receiving a response, the operation fails. A higher retry count increases robustness on unreliable connections.
