Interval_Min

Range: 6 to 3200

Default: 6

Set to indicate minimum value of ConnInterval, as defined in Section 4.5.1 of Vol 6 Part B of Core v4.2.

Interval_Max

Range: 6 to 3200

Default: 6

Set to indicate maximum value of ConnInterval, as defined in Section 4.5.1 of Vol 6 Part B of Core v4.2.

Latency

Range: 0 to 500

Default: 0

Set the latency of the Bluetooth low energy wireless technology packet. Latency is connSlaveLatency defined in section 4.5.1 of Vol 6 Part B of Core v4.2, and shall be an integer in the range of 0 to ((ConnSupervisionTimeout / (ConnInterval * 2)) - 1), it shall also be less than 500.

Timeout

Range: 10 to 3200

Default: 10

Set the timeout of the Bluetooth low energy wireless technology packet. connSupervisionTimeout = Timeout * 10 ms.

Preferred Periodicity

Range: 0 to 3200

Default: 0

Set to indicate a value the connInterval is preferred to be multiple of. It is in units of 1.25 ms. A value of zero means not valid. It shall be less than or equal to Interval_Max.

Reference Connection Event Counter

Range: 0 to 65535

Default: 1

Set to indicate the value of connEventCounter relative to which all the valid Offset0 to Offset5 fields have been caculated.

Offset 0

Range: 0 to 3200, 65535

Default: 3

Set to indicate the possible values of the position of the anchor points of the LE connection with the updated connection parameters relative to the ReferenceConnEventCount. Offset0 to Offset5 fields are in units of 1.25 ms and are in decreasing order of preference, that is, Offset0 is the most preferred value followed by Offset1 and so on. Offset0 to Offset5 shall be less than Interval_Max. A value of 0xFFFF(65535) means not valid.Valid Offset0 to Offset5 filds shall contain unique values. Valid fields shall always be before invalid fields.

Offset 1-5

Range: 0 to 3200, 65535

Default: 65535
