The invention is further described with reference to the following figures and detailed description.
As shown in fig. 1, the present invention provides a bluetooth mesh multi-gateway local and remote control coexistence method, which comprises the following steps:
s101, obtaining instruction information and an instruction serial number issued by a local or gateway.
S102, judging whether the connection state of the equipment exists in the local connection and the remote gateway connection.
And S103, if yes, shielding the instruction information issued by the gateway by the equipment according to the issued instruction serial number, and processing the instruction information issued locally.
In the embodiment, whether the issued instruction information is from the local or the gateway is identified through the instruction serial number, and only the locally sent instruction information is received for the connection state existing in both local connection and remote gateway connection, so that when local and remote coexistence is realized, one message instruction device is only executed once; saving communication resources and repairing the risk problem of data disorder.
As shown in fig. 2, another bluetooth mesh multi-gateway local and remote control coexistence method is provided in the present invention. In the method, the step of S101 obtaining the instruction information and the instruction serial number issued by the local or gateway further comprises:
s201, when the client uses MQTT to issue the local instruction message, a random number is randomly generated and used as a local instruction sequence number.
S202, when the server side issues the remote instruction message, a random number is randomly generated to serve as a remote instruction serial number.
Whether the local instruction message sent by the client side through the MQTT or the remote instruction message sent by the server through the gateway far-end gateway is used, a unique random number is randomly generated to serve as a local instruction serial number or a remote instruction serial number and serve as a basis for identifying an instruction information source of the equipment.
In the present embodiment, the instruction sequence number generation is implemented by:
// support multiple gateways, maximum sequence number of newly added 3 byte random number 16777215
if(randonS＝＝0||randonS＝＝16777215){
randonS＝arc4random()％16777215；}
V/now pv =2.1
NSData*publishData＝[TYMQModel getPublishData:[pv tp_toDouble]devId:@""data:data localKey:localKey protocol:protocol time:time publishS:randonS publishR:0]；
randon s + +; // increment
If S103 is yes, the step of checking the obtained command serial number by the device, and receiving the command information with the command serial number consistent with the local serial number further includes:
s203, the device checks the acquired command serial number and judges whether the received command serial number is a local command serial number.
And if so, processing the instruction information corresponding to the instruction serial number.
And S205, if not, shielding the instruction information corresponding to the instruction serial number.
S206, the equipment sets the current unique timestamp mark for detection and filters redundant repeated instruction information.
In this embodiment, the filtering step is implemented by:
void app_mesh_api_cmds(u8len,u8*pData){//get
int sno＝(((u32)pData[MESH_DATA_SNO])<<16)|
(((u32)pData[MESH_DATA_SNO+1])<<8)|((u32)pData[MESH_DATA_SNO+2])；
for (u 8i =1
j＝(mMeshDataFifo.index+MESH_DATA_FIFO_SIZE-i)％MESH_DATA_FIFO_SIZE；
u8*p＝mMeshDataFifo.meshdata[j].data；
int sno2＝(((u32)p[MESH_DATA_SNO])<<16)|
(((u32)p[MESH_DATA_SNO+1])<<8)|((u32)p[MESH_DATA_SNO+2])；
if(sno2＝＝sno)return；}}
Through the steps, the equipment can identify whether the obtained instruction serial number is the local instruction serial number, only process local instruction information with the local instruction serial number, and only execute the repeated instruction once through setting the current unique timestamp for detection.
