Hi,

The spec says that: "Quality measurements in the receiver of one
device can be used to dynamically control the packet type transmitted
from the remote device for optimization of the data throughput."

The question is, is it done automatically or not? May we assume that
LM is smart enough to measure the RF channel and based on it changes
automatically the packet type ?

If not, is there any point in bluez that we can talk with LM?

Regards,
