I am new to both raspberry pi and Simulink and also networking generally. I am interested in deploying Matlab functionality to the pi and have set up the Simulink support package to facilitate this. One of the things I am interested in doing is having the pi running independently on a network and intermittently reporting on its activity. I am not sure of the most sensible protocol to employ for achieving this. I don’t particularly want to have a computer always listening for pi activity on the network, however, if this is necessary then I can do this. One option I thought would be to utilise the Simulink block ‘to file’ to write various data to a file on the pi. I can then retrieve this file via the getFile java method of the raspberrypi object that I can instantiate when I want to check on the pi activity. However, one problem with this approach is that I need to stop the simulink model running to move the file. When I restart the simulink model the existing file is overwritten. In practice I don’t really want to have to stop and start models running I simply want them to make available any data they have accumulated. If the pi could simply send this file to another computer on the network this would be ideal. However, I did notice various blocks in the support package, such as UDP send and TCP/IP that could potentially be more appropriate ways of achieving this type of communication. Any advice on whether these might offer a more appropriate implementation would be welcome.
