Bluetooth LE Property 0x12 - Connection Parameter Update Request
Control
Bluetooth LE Property ID:
0x12
Get Property: Yes
Set Property: Yes
Non-Volatile: Yes
Default value: 0x01 (send connection parameter update bit is set)
This property is a one byte value whose bits control various connection parameter update features. Bits 7-
1 are reserved for future use and should always be set to 0.
Bit 0 =
Send Connection Parameter Update
bit. When this bit is set to 1, the device sends a connection
parameter update request once after each Bluetooth LE connection.
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.
