请问每次使用完RF_runCmd函数后，是否需要关闭RF驱动

没有要求每次都要关闭

区别查看下面的注释说明

/**
 *  @brief  Signal that radio client is not going to issue more commands in a while. <br>
 *
 *  Hint to RF driver that, irrespective of inactivity timeout, no new further
 *  commands will be issued for a while and thus the radio can be powered down at
 *  the earliest convenience. In case the RF_yield() is called within a callback,
 *  the callback will need to finish and return before the power down sequence is
 *  initiated. Posting new commands to the queue will cancel any pending RF_yield()
 *  request. <br>
 *
 *  @note Calling context : Task
 *
 *  @param h       Handle previously returned by RF_open()

/**
 *  @brief  Close client connection to RF driver
 *
 *  Allows a RF client (high-level driver or application) to close its connection
 *  to the RF driver.
 *  RF_close pends on all commands in the command queue before closing the connection.
 *  If a client has access to the radio by using RF_RequestAccess API, and the same client calls RF_close,
 *  then the connection to the RF driver is closed immediately without waiting for the access duration to be over.

**
 *  @brief  Abort/stop/cancel single command in command queue.
 *
 *  If command is running, aborts/stops it and posts callback for the
 *  aborted/stopped command. <br>
 *  If command has not yet run, cancels it it and posts callback for the
 *  canceled command. <br>
 *  If command has already run or been aborted/stopped/canceled, has no effect.<br>
 *  If RF_cancelCmd is called from a Swi context with same or higher priority
 *  than RF Driver Swi, when the RF core is powered OFF -> the cancel callback will be delayed
