Added the concept of wide band. Currently not used but state is
properly tracked in accordance with data rate selection.
Default channel is changed to 64 in begin method. That needs to move
anyways.
Automatic ACKs can now be adjusted on a per pipeline bases.
Its now possible to both get and set the current PA level. LNA is obsolete in P variant.
CD is obsoleted in P variant. Can now check both CD and RDP levels. Will follow through in the future to determine if there is any real difference. Aside from dBm floor and slight changes in internal behavior, they appear identical in interface and function.
Fixes a bug in openReadingPipe which was excluding the 5th pipline. We have 6-pipelines, 0-5, so excluding the 5th (<5) would only allow for four active pipelines.
