Bluetooth LE Property 0x0B - Desired Supervision Timeout
Property ID: 0x0B
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: 0x01F4 (5000 milliseconds)
This two-byte property, in least significant byte order, contains the value of the Timeout Multiplier sent in
10 millisecond units that the device sends to a Bluetooth LE host in a CONNECTION PARAMETER
UPDATE REQUEST. See the Core Bluetooth Specification for details. Only values between 10 and
3200 are valid.
After the host changes this property, the device must be reset before the changes will take effect.
