intervals to all of the Consumer Tags.)
The RPI may change every time a connection is established.
Example: When connections are established in the order of 1)
shown below
Consumer Tag (RPI = 100ms)
Consumer Tag (RPI = 150ms)
Consumer Tag (RPI = 50ms)
Consumer Tag (RPI = 100ms)
Consumer Tag (RPI = 150ms)
Consumer Tag (RPI = 50ms)
Consumer Tag (RPI = 100ms)
Consumer Tag (RPI = 150ms)
Consumer Tag (RPI = 50ms)
