[0084] Step A1: Device A carries a token, initializes the OTA client, establishes an MQTT connection with the OTA server, and subscribes to the v1 / devices / me / attributes, v1 / devices / me / attributes / response / +, and v2 / fw / response / + / chunk / + queues;

[0085] Step A2: Device A sends a firmware upgrade package information query request to the OTA server through the v1 / devices / me / attributes / request / ${requestId} queue (step A2.1), so that after receiving the firmware upgrade package information query request, the OTA server queries the upgrade status of other devices in the same local area network as device A (step A2.2), and when it is determined that there is no upgraded device in the same local area network, the OTA server obtains the firmware upgrade package from the console (step A2.3), and the OTA server feeds back the firmware upgrade package information stored in the OTA server to device A;
