You work for a logistics service provider which operates hundreds of trucks.
Most of the trucks are equipped with several sensors for tracking the routes, monitoring the temperature of the shipments, monitoring speed etc.
You have built an IoT solution which organizes all the end devices into a centralized system, making use of IoT Central as the central management platform.
On the IoT Central dashboard you notice that not all the data from your device TempSensor1004 reaches the cloud.
You start debugging on the device and you repetitively receive error code 429
What action should you take?
Click on the arrows to vote for the correct answer
A. B. C. D.Correct Answer: B.
Option A is incorrect because this type of error doesn't necessitate calling the customer support.
Option B is CORRECT because error code 429 shows that the device is affected by throttling, and that's why some messages don't arrive.
Try decreasing the frequency of the send operation under the throttling thresholds.
Option C is incorrect because in case of authentication issues, error code 401 is thrown.
Option D is incorrect because it is the error code 400 that indicates validation or parsing problems.
References:
The error code 429 suggests that the device is being rate-limited by the IoT Central platform. This means that the platform is receiving too many requests from the device within a given time period, which is causing it to throttle the device and reject some of its requests. To resolve this issue, the following actions can be taken:
B. Reduce the send frequency of messages: The device is sending too many messages to the platform, which is causing the rate-limiting. By reducing the frequency of messages sent by the device, the load on the platform can be reduced, and the rate-limiting issue can be resolved. This solution can also help conserve battery life on the device.
C. Check if the device has the right credentials: It is possible that the device is sending requests to the platform with invalid or expired credentials, which is causing the platform to reject the requests. By verifying that the device has the correct credentials, the issue can be resolved.
D. Check if the body of the requests is of valid format: It is possible that the requests being sent by the device are not formatted correctly, which is causing the platform to reject them. By checking that the requests are of valid format, the issue can be resolved.
A. Raising a ticket for customer support is not necessary in this case as it is likely that the issue can be resolved by the actions described above. However, if the issue persists even after taking these actions, it may be necessary to escalate the issue to customer support for further assistance.
