Bluetooth LE Property 0x09 - Desired Maximum Connection Interval
Property ID: 0x09
Get Property: Yes
Set Property: Yes
Non-Volatile: Yes. Changes made to this property persist even if the device is powered off or reset. This
property should only be changed once during device configuration. Modifying this property too many
times wears out flash memory.
Default value: 0x000C (15.0 milliseconds)
This two-byte property, in least significant byte order, contains the Interval Max value in 1.25 millisecond
units that the device sends to a Bluetooth LE host in a CONNECTION PARAMETER UPDATE
REQUEST. See the Core Bluetooth Specification for more details. Only values between 6 and 3200 are
valid.
After the host changes this property, the device must be reset before the changes will take effect.
Example Get Property:
Request message (hex): 00 00 09

Example Set Property:
Request message (hex): 00 01 09 0A 00 (10 (0x0A) (12.5 milliseconds))
