+ *
+ * This command is used by a Central or a Peripheral to request a change to

+ * procedure (see [Vol 6] Part B, Section 5.1.32) or the Connection Rate Request
+ * procedure (see [Vol 6] Part B, Section 5.1.33).
+ *
+ * The Connection_Interval_Min and Connection_Interval_Max parameters are used to
+ * define the minimum and maximum allowed connection interval.
+ *
+ * The Subrate_Min and Subrate_Max parameters specify the range of acceptable
+ * subrating factors being requested.
+ *
+ * The Max_Latency parameter specifies the maximum allowed Peripheral latency in units
+ * of subrated connection events. The same maximum shall apply irrespective of the
+ * subrating factor actually chosen.
+ *
+ * The Continuation_Number parameter specifies the number of underlying connection
+ * intervals to remain active after a packet other than an empty packet is transmitted or
+ * received.
+ *
+ * The Supervision_Timeout parameter specifies the link supervision timeout for the
+ * connection.
+ *
+ * If this command is issued on the Central, then it also sets the acceptable
+ * parameters for requests from the Peripheral (see [Vol 6] Part B, Section 5.1.33).
+ * The acceptable parameters set by this command override those provided via the
+ * HCI_LE_Set_Default_Rate_Parameters command or any values set by previous uses
+ * of this command on the same connection.
+ * The Min_CE_Length and Max_CE_Length parameters provide the Controller with the
+ * expected minimum and maximum length of the connection events. The Controller is not
+ * required to use these values.
+ *
+ * If this command is issued on the Central before the devices have performed the Feature
+ * Exchange procedure, then the Controller shall complete that procedure before initiating
+ * the Connection Rate Request procedure.

+ *
+ * The description below is extracted from Core_v6.2,

+ *
+ * This command is used by the Host to determine the minimum supported connection
+ * interval and which other connection intervals (see [Vol 6] Part B, Section 4.5.1) the
+ * Controller supports.
+ *
+ * Each group shall represent a set of supported connection intervals forming an
+ * arithmetic sequence starting at Group_Min[i], ending at Group_Max[i], and in steps of
+ * Group_Stride[i]. For example, if Group_Min[i] = 0x0005, Group_Max[i] = 0x003C, and
+ * Group_Strides[i] = 0x000B, then this group indicates that the Controller supports the
+ * intervals 0.625 ms, 2.000 ms, 3.375 ms, 4.750 ms, 6.125 ms, and 7.500 ms.
+ *
+ * The returned groups should include between them every supported value that is in ECV
+ * and not in RCV but may include values in RCV. A supported value may be in more
+ * than one group. The Controller shall not include any group that only contains values
+ * from RCV or the minimum supported. If it would require too many groups to represent
+ * all supported values, then the Controller should represent as many supported values as
+ * possible.
+ *
+ * For example, if the Controller returns Num_Groups = 2, Group_Min[0] = 0x0005,
+ * Group_Max[0] = 0x0050, Group_Strides[0] = 0x0005, Group_Min[1] = 0x0050,
+ * Group_Max[1] = 0x0320, and Group_Strides[1] = 0x0008, then the Controller supports
+ * all connection interval values in RCV, all values up to 10 ms that are multiples of 625 μs,
+ * and all values between 10 ms and 100 ms that are multiples of 1 ms. If the Controller
+ * supports any other values, it should have included more groups.
+ *
+ * If the Controller only supports values from RCV, then it shall set Num_Groups to zero.
