Kodda hiçbir değişiklik yapılmadan Android SDK 4.2 örnek paketindeki Bluetooth Sohbet örneğini çalıştırıyorum. Hedefim Android 4.2.2 çalıştıran bir Nexus 7. Eşleştirilmiş bir cihaza Güvenli Bağlanmayı denediğimde bu hataları alıyorum. Connect Insecure da başarısız olur ve benzer hatalara neden olur. Bazen BT'yi yeniden başlattıktan sonra bağlantı başarılı olacaktır.Bluetooth Secureaccept() Başarısız, Nexus 7, Android 4.2.2
Bunu araştırdım ve Android 4'teki BT probs'larına çok sayıda referans gördüm, ancak bunların daha sonraki 4.2 sürümlerinde sabitlenmeleri gerektiğini düşündüm. Nexus 7 benim tek cihazım bu yüzden başka cihazlarda bunun olup olmadığını merak ediyorum.
Bu sorun için bir çözüm var mı? Herhangi bir rehberlik için şimdiden teşekkür ederiz!
GÜNCELLEME: Daha fazla araştırma yaptıktan sonra BT kaynak kümesinde hala 4.2.2'de bulunan ve BT'nin manuel olarak durdurulması/yeniden başlatılmasıyla çözülebilen bir sızıntı olduğunu gösteren this link'u buldum. Programatik bir çözüm bulmuş olan var mı?
