Update A0.86: - Added simple waterfall, accessible via menu for the time being. Does not yet check screen size so may crash the application if there is not enough space. Does central frequency +/-400 hertz. Will be the basis for a more comprehensive modem screen. - Added automatic restart of modem on change of modem modes or audio frequency. - Fixed a number of bugs: new mail keyboard not appearing automatically, application crash on modem off/modem on, status bar changed on orientation change, TX overlap on pressing Abort while client TXing, display freeze on large display buffers) - Added an About screen (accessible via menu). The Bluetooth interface is complete. More testing required to ascertain the impact on the quality of the audio as the internal DSP kicks in (normally to reduce ambient noise in the car while talking on the phone). I'll be putting out the pictures and circuit diagrams for the Bluetooth interface soon. Regards, John
