Abstract

The invention discloses a flow control method and device based on BLE GATT and a storage medium, and the method comprises the steps: receiving a first Mqtt message sent by a terminal device, carrying out the classification of the first Mqtt message, and carrying out the duplication removal of a second Mqtt message obtained through classification; regularly requesting and sending a second Mqtt message to a filter, and storing a third Mqtt message obtained by filtering into a GATT channel message pool; and sending the third Mqtt message in the GATT channel message pool to a GATT proxy device, so that the GATT proxy device forwards the third Mqtt message to each Mesh network device. Therefore, aiming at an application scene that a receiver can only process a limited number of PDUs in unit time, a flow control method is adopted, the problems of probabilistic message loss and non-real-time caused by excessive channel messages are solved, and PDU receiving and transmitting events can be received and transmitted reliably in real time.

Description

technical field [0001] The invention relates to the field of BLE Mesh networks, in particular to a BLE GATT-based flow control method, device and computer-readable storage medium. Background technique [0002] There are many reasons why the BLE (Bluetooth Low Energy, Bluetooth Low Energy) Mesh network messages of the GATT (Generic Attribute Profile Specification) channel are unreliable. For example, the BLE device is interfered by other signals, or the number of GATT channel messages is too large. More congestion may cause GATT channel message loss. Although the design of BLE spread spectrum and adaptive frequency hopping has solved most of the signal interference problems, the Mesh message of the GATT channel is not real-time mainly because the receiver can only process a limited number of PDUs (ProtocolData Unit, protocol Data unit), so the number of GATT channel messages will be large, resulting in channel congestion, resulting in unreliable BLEMesh messages. That is to...
