I wanted to parse a btsnoop log file and extract the l2cap data from it Is there any way to parse a btsnoop log capture file and extract data from it by filtering using python or any other way?. I am able to convert the .cfa file into a txt file which contains hex data. I am getting extra data with the raw data.I am able to convert the .cfa file into a txt file which contains hex data.

I am having 4010 (Paper/Proprietary) file in X12 format. Now i have to convert this X12 file to 5010 X12 file.
Please let me know a way to do it. Is there some tool or website which can help me achieving it.
Thanks,

I have a service in Windows that returns a PDF data, which it's in the database in a varbinary field. This service returns the PDF data as a Byte Array in JSON format
How can I read this data and convert it to PDF again, in my app in Xcode?
Which is the correct structure data to retrieve this byte array? NSArray? NSMutableArray?
I want to store this data, and I'm using a NSData structure...
Thanks
An NSArray would be for arrays of objects, you want an array of bytes, which an NSData is.
To get the data out of JSON, you would use the NSJSONSerialization class to extract the data from your JSON object -- the deserializer will probably return your literal data as an NSString, which you then would convert into an NSData by decoding it.
Presumably your raw data is in the JSON as Base64 or some such.
In Rails 3, I want to post the bitmap image data in JSON format to server, so I do the following steps.
1. In client, translate the bitmap image to string.
2. Encode the string in JSON format and post to the server.
3. Decode the bitmap image data of JSON format.
Now the problem is: In bitmap image, there are many 0 bytes or other unreadable bytes, after encoding in JSON format, 0 byte will be translated to /u0000, space byte will to /u000a.
In the server end, I use ActiveResource::Formats::JsonFormat.decode to decode the JSON string, but the method will stop when it meets /u0000, for example,
JSON string "\u0066\u0066\u0000\u0066\u0066" will be decoded to be "ff", and the rest three bytes will be discarded silently.
So how to resolve this problem? should I write a function to decode the JSON string myself?
You should really be POSTing that data as binary in a multipart form.
If you must encode it into a string, use base64.
I've read XML or CSV before, but I've never seen anything like EDI.
How do I read this file and get the data that I need? I see things like ~, REF, N1, N2, N4 but have no idea what any of this stuff means.
I've seen somethings about x12 but don't know if thats what I have or not, how can I tell?
-- update
Thanks guys for the quick responses. Does anyone know of a parser that I can use in .Net? In the long run, I'm going to be converting this EDI file to a CSV file...
EDI messages are defined by the X12 standard.
If you look for X12 parsers, you can find helpful information.
For example, http://code.activestate.com/recipes/299485/
Those are ANSI X12 Files the standard is managed here http://www.wpc-edi.com/
Brief tutorial on structure
Hierarchy = Loops-> Segments -> Elements -> Sub Elements.
Loops are bounded either by control segments or logically based on the standard.
Segments are separated by the segment terminator, by default ~
Elements are separated by the element separator, by default *
Sub Elements are separated by sub element separator, by default :
EDI is a delimited file format. You have to know both the line delimiter and the column delimiter (for lack of a better answer). You might, for example, see an EDI file with the following format (from http://www.slik.co.nz/HTML_help/edi_file_format.htm):
HDR|6||||
DTL|1|ABC|xyz|123|1
DTL|13|ABC|animal|334|1
DTL|11|ABC|sfdk|432|2
DTL|12|ABC|wewdc|3|1
DTL|14|ABC|qwdx|416|4
The first line is the header and tells you there are six records. The other lines are detail lines.
X12 is one standard used by EDI. You will see X12 used commonly in healthcare. If you have X12, you can examine the X12 standard to figure out how to parse.
EDI stands for Electronic Data Interchange...
It's not a specific format per-se. Generally speaking it's a flat text file of data that usually has an associated published specification. For example: "Position 23-34 is the original price as a monetary value"
You really won't be able to do anything useful with an EDI file if you don't have the defined specification that goes along with it.
Once you get the specification, I believe how to read the file will be quite clear.
Generally the process is:
1. Read/Parse the EDI file.
2. Perform any processing/transformation on that data that you need to.
3. Persist it into your local system format (tables, other flat files, whatever).
Sorry there's not much more we could tell you unfortunately.
EDI stands for “Electronic Data Interchange.” The practice involves using computer technology to exchange information – or data – electronically between two organizations, called “Trading Partners.” Technically, EDI is a set of standards that define common formats for the information so it can be exchanged in this way.

EDI is just a flat file that contain some type of hierarchy. Usually companies buy EDI translator software to parse those files and extract data and then integrate with other systems. You can also use some type of service and they will do that for you. You can try to use Amosoft EDI Serices (www.amosoft.com) and they can help you with that.
