====== FMStoIP ======

In this example enable ITxPT on Netmodule NG800 and receive specific CAN Data of the router via ITxPT implementation. As a client, we use a pc with linux-debian 10. 

Requirements: 
  * ITxPT and FMStoIP license 
  * A client, in our case linux debian 10

=== 1. Step ===
SERVICES -> ITxPT -> Configuration -> ITxPT Administratio enable.
Choose your LAN Interface, your client is connected to. In our case this is LAN1.

=== 2. Step ===
Go to FMStoIP Tab, and configure as followed:

{{:app-notes:enable_fms.png?600|}}

=== 3. Step ===
To get any FMS data from the database on the webserver, once we need to enable all possible PGN IDs on the fmstoip service. Therefore we will use a simple http request sdk script.
Please configure a [[configuration:sdk-job|sdk job]] with eventbased trigger set to "sdk-startup".
Then add the following script into the script section:

<code c fms-add-all-pgn.are>
/*DESC: This script add all avaliable PGNs fmsv4.json to the FMStoIP database.

*/

url = 'http://192.168.1.1:8085/fmstoip/addpgn';
usr = "";
pwd = "";
path = "";
pp = "";
resp = "";
//define headers
header = "content-type: text/xml";

// ALL POSSIBLE PGN VALUES [HEX]     
pgn= mkarray("F000", "F001", "F002", "F003", "F004", "F005", "F009", "FD09", "FD7D", "FDA4", "FDA5", "FDD1", "FE4E", "FE56", "FE6B", "FE6C", "FE70", "FEAE", "FEBF", "FEC0", "FEC1", "FED5", "FEE5", "FEE9", "FEEA", "FEEC", "FEEE", "FEEF", "FEF1", "FEF2", "FEF5", "FEF6", "FEF8", "FEF8", "FEFB", "FEFC");

for(i=0; i<length(pgn); i++) {
     // POST request
     f = fopen("content", "w");
     fwrite(f, '<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n');
     fwrite(f, sprintf("<PGNReq>%s</PGNReq>", pgn[i]));
     fclose(f);
     req = nb_transfer_post(usr ,pwd ,url ,path ,pp ,resp ,header);
     printf("added PGN:%s\n\n", pgn[i]);
}

Don't forget to edit your router IP in the url! It is set to default 192.168.1.1

=== 4. Step ===

* [[app-notes:avahi-on-LXC|How to set up the discovery tool avahi under an LXC container]]

Almost done, now we need to discover the services offered by netmodule ITxPT service.
As discovery tool, we use avahi-discover.
Once, started, we can click on a service to get detail information.

{{:app-notes:avahi-fmstopip.png?600|}}

Now we have the multicast address for the fmstoip service discovered, we can join the multicast group and recvice the udp messages. 
<WRAP center round tip 100%>
Note: If you are connected to other networks too, make sure to add a **route 239.0.0.0/8 via 192.168.1.1** for the multicast address.

=== 5. Step ===
Please clone https://github.com/troglobit/mtools and build the mtools:

<konsole>
timm@debian:~/git$ git clone https://github.com/troglobit/mtools
Cloning into 'mtools'...

Resolving deltas: 100% (53/53), done.         
timm@debian:~/git$ cd mtools/
timm@debian:~/git/mtools$ make

  LINK    msend
  CC      mreceive.o
  LINK    mreceive
timm@debian:~/git/mtools$ 
</konsole>

=== 6. Step ===
Now we can start mrecevie, with multiacast IP and port:
./mreceive -g 239.255.42.21  -p 15015

<code sh output.txt>
timm@debian:~/git/mtools$ ./mreceive -g 239.255.42.21 -p 15015
Now receiving from multicast group: 239.255.42.21
