Page 5: Rak7431 Networking Applications
RAK7431 RAK7431 Networking Applications RAK7431 can convert the data of RS485 devices into LoRaWAN™ that can be sent to the cloud via a standard LoRaWAN™ Gateway. Cloud servers can also actively send data to RS485 terminals to achieve two-way data transmission. Using RAK7431, what used to be a costly and time-consuming cable line network deployment can be transformed into a rapid and cost-efficient wireless network deployment. - Page 6 RAK7431 RAK7431 can work in polling mode in order to send query instructions to RS485 nodes, and convert the data returned into LoRa® frames to be relayed to the application server via a LoRaWAN™ Gateway. Figure 2 | RAK7431 polling mode RAK7431 can store a maximum of 32 query instructions in polling mode, each of which has a maximum length of 128 bytes.
