(Note: This parameter is mainly used to configure the concurrency performance of the module. That is, when various nodes concurrently
transmit data, the maximum number of nodes is supported. The higher the performance, the greater the number of concurrent systems, but the
delay in sending data. The average power consumption of the nodes will increase; the lower the performance, the higher the real-time
performance of the data sent by the nodes, but the data may be lost when the environment has large interference or multiple nodes transmit
simultaneously.)
