Listen for Incoming Peer-to-Peer Connections

What if you want to do Winlink with no internet whatsoever? Now you can accept incoming peer-to-peer connection from other station. [upbeat music] Here we have two radios and two iPhone running Radio Mail, and KH6NS on the right is going to be the listening station. So we tap the antenna, and then we go into the Listen tab. Here we can change various parameter for the session. We can select the frequency, the mode, the baud rate, and in packet we can also have a identification beacon sent as a AX.25 frame to ID your station and let, you know, other people know that we are on the air and can listen. Before we hit Start, let's select the correct radio. In Radio Mail 2.0 you can select multiple device per session, so you just tap the name and you can select it. And then we hit Start, and the radio on the right is switching frequency, and now it's listening for incoming connections. Now let's go ahead and compose a message for our station. And with peer-to-peer you have to make sure the message is addressed to the exact call sign of the station that's listening, in this case KH6NS. And we're gonna go ahead and type a message. And then the important part also is to make sure that we mark the message as peer-to-peer delivery. So you just tap the CC and From, uh, line on the message. It will expand and will reveal the toggle for P2P. So that toggle indicates to Radio Mail that this message should only be delivered when you have a radio connection to the particular recipient, and also will, um, disallow things like internet email address because you can't route it to the internet. So now we go ahead and send this email. If you notice here, the Send Now option is grayed out because that's an internet feature. You're not gonna be able to send it that way. All you can do is Hold For Radio, and this will put the message in the outbox waiting for radio session to be initiated. The message is now in the outbox, and we can look at it. You can see the identification that shows it's radio and P2P only, and that means that that message won't be sent until we connect to a KH6NS station. Before you can connect to a peer-to-peer station, you have to make sure it exists, so you can go into the directory and add a custom station, enter the information, and save it there. Uh, in my case, I did it already, so I will find KH6NS in my favorite already. So I can just go and select it. Now I can initiate a connection, but before I do that, let's select the device that I want to use to connect to my radio, the BB Link in this case. I can just hit Connect, and the radio on the left is going to change frequency to match my destination station, and it's going to start initiating a connection. And on the right-hand side you can see the session as it's being received on the peer-to-peer listening station, and the email is being exchanged. And other than that, it's behaves like a regular session. One end sends, the other one receives, and the session terminates. There you have it, a peer-to-peer session. They are not very different than session you do against a gateway. There are, uh, really only the few limitation are on the type of message you can compose and the type of recipient you can have in the message. So remember, when you compose your message, you want to make sure you flag it as peer-to-peer if you intend to send it that way. This way the application will know to hold it back, and also it can help you validate that you have the right email address that can be delivered. In this case, I'm going to try to add a internet email address that normally would be fine on a Winlink message, but if I'm going to mark this message as peer-to-peer, it's going to tell me that you can't do that and to make sure that you only have recipient that can be, um, um, reached with the, with the session you're going to initiate. Let's now stop our listening station and take a look at the message we just received. So we hit Stop. It will restore the radio and disconnect, and now we can take a look at our inbox, and here's the message that we just sent. No gateway, no internet, just a message between two stations. Mahalo and seventy-three.
