Since Bluetooth communication is short-range, this locational relationship makes it difficult for the soil moisture sensor to communicate with the gateway, which can easily lead to network anomalies or failure to form a network. In addition, if there are many devices, all Bluetooth irrigators and soil moisture sensors are connected to the gateway, resulting in high load on the gateway and system instability.
