Wireless nRF24L01+ sniffer for MySensors
-
Everything works now.
Did not see any packets coming in though but I remember having an issue with a couple of Uno's and I am not sure if this was one of them.
Anyway, I will do some more testing tomorrow.
Very exited :) -

In the meantime, please have a look at the last part I wrote, detailing the use of Wireshark and the sniffer: http://yveaux.blogspot.nl/2014/07/nrf24l01-sniffer-part-3.htmlFor tonight I'm totally done with this sniffer -- Aaaarghhh! ;-)
Btw. Could you also post stuff you had to do to get it working (just a wrapup) to my blog, to keep stuff together? Thanks!

@Yveaux Not a problem, I like being a pioneer and I greatly appreciate the efforts you put into this :)
I thought I had everything in order this afternoon.
Installed Visual C++ Redistributable Packages for Visual Studio 2012 SP 4 but forgot to test...Right now, whatever I use 'Visual C++ Redistributable Packages for Visual Studio 2012 SP 4' or (for testing purposes) 'Visual C++ Redistributable Packages for Visual Studio 2013' both x64 I still see the error message 'The program can't start because MSVCR110.dll is missing...'.
A restart should not be necessary but even a restart did not help.Uninstalling all packages and reinstalling did not help either.
Any idea?

The console application is 32bits. I don't know if the 32 bits versions are included in the 64 bits installers...

That was not the issue...
Below is the wrap-up that I also posted on your blog:
There are 3 things that I bumped into though that I would like to share with you and those that decide to use the sniffer.
-
Immediately after starting** 'Nrf24Sniff.exe -P6'** (the rest is default in my case) I got this error message 'The program can't start because MSVCR110.dll is missing...'. It basically complains that 'Visual C++ Redistributable Packages for Visual Studio 2012 SP 4' is not installed but that is not true. After doing a bit of searching I found that I needed to** install or repair 'Microsoft Essentials'**.
Once this was done the program works as expected (don't ask me why, this must be pure MS genius). -
Once Wireshark was started like described I noticed that the Nrf24Sniff console window displayed a *'Wait for sniffer to restart' *message. The author mentions that this will only take a few seconds but in my case I actually needed to reset the Arduino for it to go away. No exception.
-
After creating the correct setup in Wireshark I expected data to show up but it did not. I wondered why and ran a complete test to see that the Ardiuno was ok, radio sufficiently powered etc. but that was all ok. I then re-read the article and found that the author says 'when monitoring MySensors 1.4beta traffic (at non-default 1Mb/s)'. I completely missed this and that caused the issue.The MySensors 1.4beta is set to 250b/s by default. Once I started the sniffer like 'Nrf24Sniff.exe -P6 -r2' everything works as expected.
Now I have to find some time to read the third article so that I understand what happens on my screen :)
Anyway, good stuff and a big thank you goes to @Yveaux ...

@Yveaux can you do me a favour ? colord blind people cannot read red on black... they represent 10% of the population...
Also, does your software runs under nano ;-)

@Yveaux ah a vb programmer... you need to install the msvcr110.dll msvcr110.dll t to make it start with wine. (does not work with mono...)
then I have wireshark but I don't understand what to do next...
"Connect Wireshark to \.\pipe\wireshark to continue..." -

I can't think of a reason why it would not work.
Just try (once you can read the blog :) ).@marceltrapman yes but for the reason just above I can't... had to select all the text to read...
mono Nrf24Sniff.exe Cannot open assembly 'Nrf24Sniff.exe': File does not contain a valid CIL image. -

I was really... Joking with you :)
BTW I can imagine that trying to make this work with wine will give you all sorts of issues that are hard to comment on for those that don't use it.

What is red on black? Some coloring in Wireshark?
If so, I don't choose the colors, Wireshark does! I just mark it as 'warning'.
Have a look at Edit->Preferences->User Interface->Font and colors to see if you can change it to your likings.AH, now I see what you mean! The text on my blog :-)

I didn't test it, but don't see why it shouldn't!

It is your blog.
Mostly white on black but, when highlighted, also red on black... -

"Connect Wireshark to \.\pipe\wireshark to continue..." -
@epierre It's not written in vb! Shame on your! It's pure hardcore C!
If you get it to run on Linux (?) using Wine then let us know please! -
@Yveaux yes I did... but I stopped here not knowing how to do it:
Connect Wireshark to \.\pipe\wireshark to continue...@epierre It's in the blog: start a new command window and navigate to the wiresrak directory (c:\program files\wireshark)
Then run:wireshark -k -i \\.\pipe\wiresharkAnd it should automatically connect to the named pipe (which is written to from the nrf24sniff.exe tool) and start capturing.

-
@Yveaux yes but through wine are they POSIX compliant so my linux wireshark can connect to it ?
@epierre I guess not, as Linux uses files as named pipes and \.\pipe\wireshark is not a regular Linux file path...
Furthermore the Wireshark dissectors should compile on Linux, but I didn't test it.
You could try to also run windows Wireshark through Wine, maybe the named pipes will pass the data along just fine... -

I changed the nrf24snif.exe to explicitly reset the Arduino (works for Uno) by lowering DTR/RTS lines. Should work for (most?) other Arduino's too, but I don't have any other to test one.
For me it seems to work now. Could you test if this works stable for you too?Oh yeah, I added support for some status leds to the Sniffer, connected to A0..A4 and via resistors to GND:
- A0 sniffer monitoring (LED turns off during reset)
- A1 sniffer receiving a packet
- A2 sniffer transmitting (serially) a packet
- A3 new configuration received
- A4 buffer overflow
