Bluetooth LE Property 0x0D - Minimum Advertising Interval (PCI Bluetooth LE Only)
Property ID: 0x0D
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: 160 (100 milliseconds)
This two property, in most significant byte order, contains the device’s minimum Bluetooth LE
advertising interval in 625 microsecond increments. This property, combined with
Property 0x0E - Maximum Advertising Interval (PCI Bluetooth LE Only)
, specifies the Bluetooth
LE advertising interval the device uses. Smaller advertising intervals cause the device to consume more
power when advertising, which may be a concern when running on battery power.
Only values between 32 (20ms) and 65535 (40.96s) are valid. The host may need to adjust the maximum
advertising interval property when changing this property; if the maximum advertising interval is less
than the minimum, the device may behave unpredictably.
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 0D
Response message (hex): 01 00 06 40 (1000ms / .625ms) = 1600 (0x0640)
Example Set property:
Request message (hex): 00 01 0D 06 40 (1000ms / .625ms) = 1600 (0x0640)
Response message (hex): 01 00
