Release Notes - 2.0.0

New + Improved

Transceiver capabilities for use in bi-directional applications.
- Transmits and receives simultaneously on different non-overlapping frequencies.
- Options for the transceiver type (combination of transmitting and receiving tone profiles) are as follows:
  - Transmit PKAB2 tones while receiving Standard2_Wideband transmissions.
  - Transmit PKAB2 tones on a higher frequency while receiving PKAB2 transmissions from a lower frequency.
  - Transmit PKAB2 tones on a lower frequency while receiving PKAB2 transmissions from a higher frequency.
  - Transmit Standard2_Wideband tones while receiving PKAB2 transmissions.
Audio mixing disabled by default for iOS.
SNR/EVM values have been adjusted to return the raw values instead of strings indicating quality.
New interface functions:
- validateToken - verifies if the SDK token provided is approved (see docs for more information).
- getExpirationDate - gets the expiration date of the sdk token provided (see docs for more information).
Adjusted how our Docs look!

Transceiver screen in sample apps to match our new Transceiver option for bi-directional communication (iOS & Android).
Radius sample app updates:
- Feedback UI showing the change in SNR/EVM values represented by a microphone symbol with a colored circle (iOS & Android).
- Themes and color (iOS & Android).
- Adjusted layout of Transmit and Receive screen (iOS & Android).

Updated dependent Armadillo library to 10.8.0
Callbacks added for improved error handling
Improved tone completion reporting
- transmitComplete callback is now issued when a tone has played out of the device speaker
Interface function for adjusting the SDK error logging at runtime
Clarified error information when an improper SDK token is provided
Removed support for 44.1kHz sampling rate
- Modern devices are all capable of handling 48kHz, removing this reduces our code complexity increasing overall productivity.
Removed compression tone profile from documentation and SDK usage
Increased default output volume to 80% (iOS)
- This will result in overall default range increase and is still configurable by the developer.
Refactored documentation to remove all references to creating a bridging header (iOS)
- This header is no longer necessary with the current framework
Updated underlying PortAudio dependency (Desktop)
No longer distributing Win32 or MacOS SDKs, but available upon request (Desktop)
No longer distributing the python interface, but available upon request (Desktop)
Added documentation for recommended audio test hardware (Desktop)
Added new constructor for Radius object which does not require the Lifecycle object (Android)
Added clarifying information on which exceptions are fatal or non-fatal (Android & iOS)
React Native wrapper SDK and sample application available upon request (iOS & Android)

Removed use of -ffast-math compiler optimization, causing bad performance issues with Xcode 12.5 (iOS)
Disabled using NEON at compile time (Android)
- An incompatibility of NEON with our FFT library was causing crashes on certain armv7 devices

Added tone profile strings to sample applications for ease of use (Desktop)
Informative message displayed when trying to send a large payload using standard2 or standard2_wideband (iOS & Android)
- In these situations it is recommended to use pkab2 or pkab2_wideband for better performance unless longer range is required

Sendpayload/startbeacon buttons disabled when trying to send an empty tone (iOS & Android)
Payload text editor and size buttons re-enable when the SDK goes from disabled to idle (Android)

New standard2 and standard2_wideband profiles added
- These profiles are ideal for use cases with long range requirements and reliability

Added optional recording functionality to the sample application
- This feature is intended to be used for debugging purposes when having issues receiving tones
