Hello everyone, I have a question about the capability of motorola xir M8668i at TCP/IP connection. Looks like I am going to get several of used radio with the same type as what I mentioned before and I would like to experiment on them by connecting all of these radios through TCP/IP network. As far as I know, smartPTT application is able to send files between radios using DMR signal alone from one computer to another. I know the transfer rate will be very slow since it will use DMR RF signal, but it does not matter since it is for experiment only. However, what I don't understand here is what type of connection is used to connect between the radio and the computer and which port should I used to connect both of them. Furthermore, I would like to implement this kind of connection with smaller linux-based computer by utilizing serial/uart connection between the computer and the radio. Do you know what kind of setup (cables, etc) I need to connect them, which port should I use to do this and and which software can I use to program the radio in order to be able to utilize TCP/IP connection? any reference (links, websites, etc) that you can provide here is really appreciated, thx before.
