Incompatible Changes and Possible Transition Issues

  • Cross-compiling requirements have changed, due to the updated V8 engine. Specifically, cross-compiling from a 64-bit host to a 32-bit target requires a 32-bit toolchain on the host, and the capability to run 32-bit executables created by that toolchain on the 64-bit host.
  • The BtLE APIs have been changed to use Poco::UUID instead of std::string for UUID parameters.
  • The BtLE PeripheralBrowser interface has changed. However, since this interface was not implemented before, this should not be an issue.
