Has anyone tried using RadioMail on ipad or Iphone on an Ipad connected to IC-705 connected via Bluetooth?
IC-705 does no have a packet TNC, so that setup is not currently supported.
From what I understand BLE in IC-705 will connect to audio accessories like a headset but can't connect to an iPhone in that way, only for serial CAT control. The WiFi interface would have to be used to expose the sound-card in the IC-705.
So for such configuration to work for packet, an AFSK modem, and support for the audio streaming and cat control of the IC-705 over WiFi need to be implemented in RadioMail. It's doable, but a sizable development effort. Perhaps if the Venn diagram of RadioMail user and IC-705 owner is large enough, that may be worth contemplating.
