Bluetooth LE Property 0x0C - Desired Minimum Connection Interval
Bluetooth LE Property ID:
0x0C
Get Property: Yes
Set Property: Yes
Non-Volatile: Yes
Default value: 10 (12.5 milliseconds)
This property is a two byte integer in least significant byte order, in 1.25 millisecond increments, that
contains the
Interval Min
value the device sends to the Bluetooth LE host in a CONNECTION
PARAMETER UPDATE REQUEST (see the core Bluetooth specification for details). Only values
between 6 and 3200 are valid.
This property is stored in non-volatile memory, so it persists when the device is power cycled. This
property would typically only be changed once during device configuration if needed. Modifying this
property too many times wears out flash memory.
When this property is changed, the device must be reset (see
) or powered
off for at least 30 seconds, then powered on, before the changes will take effect.
