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

BLE-Stack

EDIT

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

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows}
\usetikzlibrary{positioning}

\begin{document}
\begin{tikzpicture}[align=center,>=latex',font=\sffamily]
\tikzstyle{Dotted} = [draw=black,dashed,thick,rectangle,minimum width=120mm,minimum height=33mm]
\tikzstyle{Normal} = [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)};
\end{tikzpicture}
\end{document}

This code results in this output

enter image description here

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?

    For the dash pattern \path[](HCI0) -- (HCI1) node[midway,fill=white](aux){Host Controller Interface\\(HCI)}; \draw [dash pattern={on 5mm off 3mm},line width=1.2mm](aux)--(HCI0)(aux)--(HCI1); – AndréC Aug 31 at 20:15

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

  • When I add \draw(current bounding box.south east) rectangle(current bounding box.north west); to the end, I can see about 1 cm white space at the top of the tikz image. How can I reduce this space? – Passe Sep 1 at 6:43
  • You can shift like this \draw(current bounding box.south east) rectangle([shift={(0mm,-8mm)}]current bounding box.north west); – AndréC Sep 1 at 7:05
  • Yes, but this is just a hack isn't it? I found out, that the white space is produced through my label definition label=left:Host,label={[label distance=5.5mm]}. If I activate draw labels I can see a label above the Host. Is there a way just to draw the left label and not the label above? – Passe Sep 1 at 7:09
  • It is the syntax of TikZ coordinates that allows you to specify local options as described on page 133 of the 3.1.4b manual. I quote The general syntax is ([<options>]coordinate specification). This allows coordinates to be adjusted locally. – AndréC Sep 1 at 7:21
  • You can simplify your code by using styles as Mr. Al Jumaily and Zarko did in their answer. It is still heavy, but it is normal that it is for the first time. Using styles makes it easier to understand the code and maintain it over time. – AndréC Sep 1 at 7:35

With use of TikZ libraries fit and positioning, for all positioning distances are used only values defined in node distance. This enables to write clear, concise and consistent code:

Edit: if you like to change distances of nodes' labels from nodes (on consistent way), you only need to add label distance = <desired amount> to tikzpicture options (added now to MWE below.

Also, if you like to change distance between nodes and doted nodes around it, for example have different in horizontal direction from vertical, you only need to add inner xsep and inner ysep in style for node FIT. For example:

FIT/.style = {draw, semithick, dotted, fit=#1,
              inner xsep=4mm, inner ysep=2mm},  % here you can adjust inner distance of node}, 

All aforementioned I now added to my MWE.

\documentclass[tikz, border=3mm]{standalone}
\usetikzlibrary{fit,
                positioning}

\begin{document}
    \begin{tikzpicture}[
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,
                 inner xsep=4mm, inner ysep=2mm},  % here you can adjust inner distance of node
                                                   % this adjust you need to consider at defining the width of the top nodes
label distance = 2mm,
      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[line width=1.2mm, dash pattern=on 5mm off 3mm]  % solve your first question
    (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=106mm, above= of host,
             label=left:Application]        {Application\\(APP)};
\end{tikzpicture}
\end{document}

Result is:

Everything here is placed with respect to the components in the diagram. With the comments, the logic is very easy to follow.

This answer shows the differences between my first try solution in the question and my final solution. The differences are located in the label definitions, please see my comments.

    Please, explain what id in your answer different from others, especial from accept one. From image i can only conclude, that you add borders around labels (what wasn't demand in your question). – Zarko Sep 1 at 8:15
  • Sorry, beside to changed distance of labels Controller, Host and Application I don't see any differences :-). that means that you add new size of label distance only ... you should mentioned this demand at least in comments below received answers ... see my edited answer. BTW, desired changes of received answers in form of last answer is not fer to people who prepare answers according to your question. – Zarko Sep 1 at 9:03
