Problems solved by technology
The LORAWANLORAWAN gateway and the network server are connected through standard IP. The more protocols used between the LORAWANLORAWAN gateway and the network server are based on the UDP protocol. Using the UDP protocol can achieve higher file transfer efficiency, but the UDP protocol is in the transmission At the same time, there are problems of poor reliability of the file, such as the loss of transmitted data packets, and the problem of tampered messages. At the same time, it can only be limited to the problem of a single data message transmission and less data retransmission mechanisms.

Embodiment Construction
[0047] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0048] Such as figure 1 As shown, the embodiment of the present invention provides a LORAWAN-based file transfer method, which is applied to the network server and the LORAWAN gateway, and is applied to the network server to upload files to the LORAWAN gateway, including:
[0049] S11: The network server sends a file upload request packet to the LORAWAN gateway;
[0050] S12: After the LORAWAN gateway receives the file upload request packet, it responds to the file upload request packet to the network server; the LORAWAN gateway creates a corresponding file for storing the data packet received from the network server;
[0051] S13: After the network server receives the file upload request packet, it divides the file to b...

The invention relates to the field of communication technology. The embodiment specifically discloses a file transmission method based on LORAWAN, which sends a file upload request packet to the LORAWAN gateway through a network server; after the LORAWAN gateway receives the file upload request packet, it responds to the file upload request packet to the network server ; After the network server receives the file upload request packet, it divides the file to be sent into several data packets that meet the file upload requirements of the LORAWAN gateway; the network server sends data packets to the LORAWAN gateway one by one until the file to be sent is sent. It achieves better reliability when data files are transmitted between the LORAWAN gateway and the network server, and ensures the integrity of the data and the efficiency of the transmission.
Description
technical field [0001] The invention relates to the technical field of communications, in particular to a LORAWAN-based file transfer method. Background technique [0002] LoRa technology is an ultra-long-distance, low-power IoT solution provided by Semtech. LORAWAN The LORAWAN gateway is the core of the LORA network, a bridge between the terminal and the network server, and also a multi-channel transceiver. The LORAWANLORAWAN gateway and the network server are connected through standard IP. The more protocols used between the LORAWANLORAWAN gateway and the network server are based on the UDP protocol. Using the UDP protocol can achieve higher file transfer efficiency, but the UDP protocol is in the transmission At the same time, the file has poor reliability, such as the loss of transmitted data packets, and the problem of message tampering. At the same time, it can only be limited to the problem of a single data message transmission and few data retransmission mechanisms....
