Sending and receiving email
Each message you compose can be sent over the internet or wait for a radio session. There is no separate Telnet mode. Delivery over Wi-Fi or cellular is part of normal messaging.
Send Now
When you compose a message, choose Send Now. RadioMail delivers it over Wi-Fi or cellular when a connection is available. If you are offline, the message stays in the Outbox until you are online or you start a radio session.
Hold for Radio
Choose Hold for Radio to keep the message in the Outbox until you start a radio session. Use this when you want to operate over the air, or when you expect to be offline.
Peer-to-peer
Peer-to-peer is a special way you can identify message that you intend to deliver to another operator directly, bypassing the Winlink systems.
A peer-to-peer message is limited to the To recipient. It is held for radio automatically, and it is delivered only when you connect directly to a station whose callsign matches that recipient.
While composing, tap Cc, From: and turn on Deliver only when peer-to-peer.
Fetching mail
Fetch New Messages Automatically is on by default in Settings → Messages. RadioMail checks for new mail periodically while it is open. Background fetch uses Wi-Fi or cellular and follows iOS scheduling, so it can lag depending on battery and other system conditions.
Pull down on Mailboxes or the Inbox list to fetch now.
Outbox
Held-for-radio messages show a radio icon. Peer-to-peer messages show a radio icon plus P2P.
If you want to force send messages in your Outbox when you are online, tap the paper airplane to send queued mail.
Peer-to-peer messages always stay in the Outbox until you connect to the recipient station over radio.
