New Version 2.4.0 of SmartSDR for iOS available

ThisUserDoesNotExist Company Adviser ✭✭
edited August 2020 in New Ideas
I have just released a new Version of SmartSDR for iOS that contains the following changes and bug-fixes:

■ Aligned with the latest FlexRadio SmartSDR Version 2.x
■ Improved slice touch / moving capabilities
■ Optional display of the S-Meter or dBm value in slice flag
■ Split mode now back working again
■ Wrong Antenna selection fixed
■ Now ATU is only available if the Radio has an antenna Tuner included
■ Bandmap IARU changes are now regarded without App restart
■ Further improvements for the iPhone X
■ Parts of the App have been rewritten and the App was ported to Swift 4 which results in additional speed and stability improvements

Also, a new Feature (Tool) has been added:

■ Voice Macro to record and playback recoded voice (e.g. for calling CQ or responding with 599)

This App is still backward compatible to Version 1 of SmartSDR or can run with the latest SmartSDR version, including SmartLink.

The next update is already under development.

    Marcus -- Great work. I really love the app and am extremely impressed by how it offers the clever design of SmartSDR in a way that works so well on a small screen. 

    I have one small feature request.  I would like to be able to choose speaker vs headphones without having to go into the menu and scroll. I think a toggle button to select speaker vs headphones should be right near the mute audio button.  

    Please take this suggestion with an appropriate grain of salt.

    V.2.3 is the current version visible here in the US as of 15 min ago. Sometimes I understand versions of software originating in other countries take time to migrate to other Apple App stores in other regions. We will try again tomorrow . I searched for both the App and tried checking updates, version 2.3 only. Thanks for the encouragement that it must be it’s in route.

    Thank you for your ongoing work on your app. Would like to report a critical bug - Bluetooth headset no longer works with SmartSDR for IOS. V2.4. I have tried two different headsets and both are no longer available for selection when running SmartSDR for IOS even though device tethered correctly to the device and works with other applications.

    When I ran the old version it automatically asked if I wanted to upgrade. I did not have to use the Apple store.

    Thanks for reporting this Bluetooth issue. I found the cause and just sent an update 2.4.1 to Apple.

    I did introduce a new larger receiving buffer which increased audio quality while using the internal speakers but they seem to be too large for the smaller Bluetooth packets. This can now be disabled and is disabled per default.

    Hope they will release it soon.

    Thanks Marcus for the great work. Can the app still keep radio on while needed to logg into web browser for other tasks? I use iPad Pro and this is a little tiresome as it works today. Or am I misstaken myself?

    Hi Kari,

    yes, there are two solutions for that:

    1.) In the App Settings set "Disconnect on close" to OFF. This way, you can leave the App, it continues in the Background and the Radio connection will not be closed.


    2.) Use multitasking / split view so you can have SmartSDR for iOS and your Browser Safari side by side and use both even simultaneously

    Below is an Image where I showed Mike, VA3MW how this would look when using my App and Safari side by side with his Remote Control unit.

    Thanks everybody!

    Ok, version 2.4.1. has been released yesterday, a few hours after I sent it to Apple. That was quick.

    I have tested that version with the Parrot BT Headset, with a Logitech 800 and Apples EarPods. All seem to be working well now. Also Voice Macros can be recorded with all of them.

    To solve the BT problem, I added a new switch in the settings called "Large Buffer" which needs to be turned off for some of the Headsets.

    In other cases, where the headset works with it or if you use the speaker, you may want to switch "Large Buffer" on because this will reduce the possibility of audio dropouts. That was my intention why I increased the internal iOS Audio buffer size, not expecting that this may cause these BT problems.

    Please, all of you who had these problems, please try again with 2.4.1. and let us know if it works.

    Thank you all,
