#include "BS_API.h"
int BS2_GetSlaveDevice(void* context, uint32_t deviceId, BS2Rs485SlaveDevice** slaveDeviceObj, uint32_t* slaveDeviceCount);


  • [In] context : Context
  • [In] deviceId : Device ID
  • [Out] slaveDeviceObj : Slave device list pointer

The slaveDeviceObj variable needs to return the memory to the system by the BS2_ReleaseObject function after being used.
