Research direction
Start by examining the bleno source code for secure write implementation, particularly in the Characteristic class. Test the scenario on a physical iOS device with Xcode debugging to capture more detailed error logs. Check if the issue persists with the latest version of bleno and iOS. Consider asking the maintainer for clarification on expected behavior.
