Any utility payload exceeding this restrict should be fragmented by the machine utility and transmitted over a number of messages. WiFi location payloads with just one or two MAC addresses can slot in a single Sidewalk message. Nevertheless, payloads with GNSS NAV messages (roughly 50-70 bytes) or a bigger variety of WiFi MAC addresses require fragmentation and de-fragmentation. The Decode Lambda operate shops decoded fragments in a cache carried out in an Amazon DynamoDB desk if the machine sends a fragmented payload. The de-fragmentation Lambda operate screens the DynamoDB stream for finish fragments after which reassembles these bigger payloads.
3. Resolve Geo-Location – As soon as a whole location payload is decoded and de-fragmented, the Lambda operate resolves the Geo-location (Latitude/Longitude) of the machine utilizing the AWS IoT Core System Location resolver (GNSS, Wi-Fi, Web Protocol, or Mobile) API. The resolved Geo-location of the machine is then printed by the Lambda operate to a MQTT matter utilized by the Amazon Location Service structure. Moreover, the Lambda operate can retailer the resolved location in Amazon DynamoDB or Amazon Easy Storage Service (S3) together with the timestamp.
4. Observe – Monitoring of the units is achieved utilizing Amazon Location Service and the structure sample offered within the AWS Options Library.  This sample makes use of a MQTT matter to obtain the resolved Geo-location in a normalized vogue that’s then handed to a tracker useful resource in Amazon Location Service by way of a Lambda operate and Amazon EventBridge. This strategy permits location monitoring to be achieved for a heterogeneous fleet of trackers by means of totally different knowledge transport and site sorts: IP primarily based, Amazon Sidewalk, LoRaWAN, and extra. As soon as the placement knowledge is offered to the tracker in Amazon Location Service, superior capabilities, comparable to Geo-fencing and asset proximity can be utilized together with reside and historic monitoring.
5. Visualize – Lastly, visualization of the units is achieved utilizing an online utility hosted with AWS Amplify and Amazon Cloudfront together with maps from companions in Amazon Location Service.
