Can anyone give me an example how to draw this BLE-Stack with tikz?

EDIT

Now, I'm very close to my wished result :)

documentclassstandalone
usepackagetikz
usetikzlibraryarrows
usetikzlibrarypositioning

begindocument
begintikzpicture[align=center,>=latex',font=sffamily]
tikzstyleDotted = [draw=black,dashed,thick,rectangle,minimum width=120mm,minimum height=33mm]
tikzstyleNormal = [draw=black,thick,rectangle,minimum width=108mm,minimum height=12mm]
node[label=left:Controller,label=[label distance=5.5mm],Dotted](Controller);
node[above left = 3mm and 6mm of Controller.south east,anchor=south east,Normal](PHY)LE Physical Layer\(PHY);
node[above = 3mm of PHY,Normal](LL)Link Layer\(LL);
node[above = 10mm of Controller.north west,anchor=north west](HCI0);
node[above = 10mm of Controller.north east,anchor=north east](HCI1);
draw[dash pattern=on 5mm off 3mm,line width=1.2mm,](HCI0) -- (HCI1) node[midway,fill=white]Host Controller Interface\(HCI);
node[above = 18mm of Controller,label=left:Host,label=[label distance=5.5mm],Dotted,minimum height=48mm](Host);
node[above left = 3mm and 6mm of Host.south east,anchor=south east,Normal](L2CAP)Logical Link Control and Adaption Protocol\(L2CAP);
node[above =15mm of L2CAP.north east,anchor=north east,Normal,minimum width=51mm](ATT)Attribute Protocol\(ATT);
node[above = 15mm of ATT.east,anchor=east,Normal,minimum width=51mm](GATT)Generic Attribute Profile\(GATT);
node[above = 15mm of L2CAP.north west,anchor=north west,Normal,minimum width=51mm](GAP)Generic Access Profile\(GAP);
node[above = 15mm of GAP.north west,anchor=north west,Normal,minimum width=51mm](SMP)Security Manager Protocol\(SMP);
node[above = 3mm of Host,label=left:Application,label=[label distance=5.5mm],Normal,minimum width=120mm](Application)Application\(APP);
endtikzpicture
enddocument

This code results in this output

There are just two questions:

1. How to start the dashed line from the left border and from the right to get a symmetrical dashed line?


2. How to delete the insertion on the left and right of the dashed line?

1. For the first question, simply name the node where the text is written, then draw the pattern from this node to the edges.

 path[](HCI0) -- (HCI1) node[midway,fill=white](aux)Host Controller Interface\(HCI);%<--- auxiliary node (aux)
 draw [dash pattern=on 5mm off 3mm,line width=1.2mm](aux)--(HCI0)(aux)--(HCI1);% pattern from center to edges

2. The second question is more complex, so I suggest that you make it another question in its own right.

documentclass[border=5mm,tikz]standalone

usetikzlibraryarrows
usetikzlibrarypositioning

node[label=left:Controller,label=[label distance=5.5mm],Dotted](Controller);
node[above left = 3mm and 6mm of Controller.south east,anchor=south east,Normal](PHY)LE Physical Layer\(PHY);
node[above = 3mm of PHY,Normal](LL)Link Layer\(LL);
node[above = 10mm of Controller.north west,anchor=north west](HCI0);
node[above = 10mm of Controller.north east,anchor=north east](HCI1);

node[above = 18mm of Controller,label=left:Host,label=[label distance=5.5mm],Dotted,minimum height=48mm](Host);
node[above left = 3mm and 6mm of Host.south east,anchor=south east,Normal](L2CAP)Logical Link Control and Adaption Protocol\(L2CAP);
node[above =15mm of L2CAP.north east,anchor=north east,Normal,minimum width=51mm](ATT)Attribute Protocol\(ATT);
node[above = 15mm of ATT.east,anchor=east,Normal,minimum width=51mm](GATT)Generic Attribute Profile\(GATT);
node[above = 15mm of L2CAP.north west,anchor=north west,Normal,minimum width=51mm](GAP)Generic Access Profile\(GAP);
node[above = 15mm of GAP.north west,anchor=north west,Normal,minimum width=51mm](SMP)Security Manager Protocol\(SMP);
node[above = 3mm of Host,label=left:Application,label=[label distance=5.5mm],Normal,minimum width=120mm](Application)Application\(APP);
endtikzpicture

With use of TikZ libraries fit and positioning, for all positioning distances are used only values defined in node distance:

documentclass[tikz, border=3mm]standalone
usetikzlibraryfit,
 positioning

begindocument
 begintikzpicture[
node distance = 2mm and 0mm,
 box/.style = draw, text width=#1, inner sep=2mm, align=center,
 box/.default = 98mm,
 FIT/.style = draw, semithick, dotted, fit=#1,
 font = sffamily
 ]
node (phy) [box] LE Physical Layer\(PHY);
node (lll) [box, above = of phy] Link Layer\(LL);
 node (cntrl) [FIT=(phy) (lll), label=left:Control] ;
%
node (hci) [box=12em,draw=none, 
 above=of cntrl] Host Controller Interface\(HCI);
draw[ultra thick, dashed] 
 (lll.west |- hci) -- (hci)
 (lll.east |- hci) -- (hci);
%
node (cap) [box, above=of hci] Logical Link Control and Adaption Protocol\(L2CAP);
node (gap) [box=44mm,
 above right=of cap.north west] Generic Access Profile\(GAP);
node (att) [box=44mm,
 above left=of cap.north east] Attribute Protocol\(ATT);
node (smp) [box=44mm,
 above=of gap] Security Manager Protocol\(SMP);
node (gap) [box=44mm,
 above=of att] Generic Attribute Profile\(GATT);
 node (host) [FIT=(cap) (smp), label=left: Host] ;
%
node (app) [box=102mm, above= of host,
 label=left:Application] Application\(APP);
endtikzpicture
enddocument

Result is:
