What are the working modes of common LoRa ad hoc network gateways

Working mode 1: Node active reporting mode
Node active reporting mode: After the concentrator sets this mode, the network access node module will enter the active reporting mode. At this time, the concentrator will automatically return a response after receiving the node data, and upload the valid data to the server.
Function description:
1. In this mode, the concentrator is in the monitoring state after it is powered on. When the supporting node module is powered on, the node module will actively send network access information to the concentrator. Assigned to each communication channel, and immediately return to the node network setting data, and finally save the node information in the database of the networked device. SPI-модуль
2. The node that receives the network access information will automatically change the channel, rate and other information according to the configuration of the network access information, automatically match the data channel (channel 2, 3, 4), and report the data periodically according to the set parameters.
Working mode two: Polling wake-up mode
Passive wake-up mode: After the concentrator sets this mode, the network access node module will enter the passive wake-up state. At this time, the concentrator will issue a preamble according to the web setting (the preamble duration is consistent with the wake-up period) to wake up all nodes on the channel on the network. And transmit the data to the node; after the data is sent, if the concentrator receives the data replied by the module, it will immediately send the next piece of data, otherwise it will wait until the receiving time expires to send the next piece of data.
Function description:
1. Before using this mode, the customer needs to set the relevant parameters of the concentrator first. After the setting is completed, the concentrator will be in the monitoring state. When the node enters the network, the concentrator will reply the network access information and save the node information. When the node is connected, the concentrator will periodically send wake-up data to wake up the node according to the set wake-up cycle, polling cycle, and polling timeout, and send the wake-up data set by the user to the node.
2. After the node receives the data, it takes corresponding actions and replies with relevant data to complete a data interaction; after that, the node enters sleep mode, and the concentrator waits for the second wake-up data to be sent in the next cycle. In this mode, a maximum of 16 wake-up data can be set. When a wake-up data poll completes all nodes (connected nodes stored in the database), the second polling data will be replaced, and the above steps will be repeated until the next polling cycle. When all polling data polling is completed, After waiting for the polling cycle to end, it will start polling again and wake up from the first data saved in the database. Модуль 4G
Polling data setting: It consists of the number of issued clocks and polling data, and takes effect in passive wake-up mode;
Number of sent messages: Determine the number of polling data below. For example, if the number of sent messages is 4, then only the data in data 1~4 will be polled; a maximum of 16 command data is supported, and the data format is "hexadecimal", please Fill in strictly according to the data format.
Polling data: The user needs to poll the data or instructions issued, input in "hexadecimal", up to 64 bytes, please be sure to input in hexadecimal format.
