मैं इसे दोनों विंडोज 732 बिट & 64 बिट पर है की कोशिश की है। मैं एचटीसी डिजायर एंड्रॉइड v2.3.3 का उपयोग कर रहा हूं।
जब मैं सर्वर से कनेक्ट करने का प्रयास ग्राहक और OutputStream
का उपयोग कर किसी भी पाठ लिखने की कोशिश, मैं त्रुटि मिलती है:
Check that the SPP UUID 00001101-0000-1000-8000-00805F9B34FB exists on server
इसके अलावा मैं अपने पीसी पर एक नया ब्लूटूथ डिवाइस जोड़ने।

मुझे पता है अगर कोई एक विचार है करते हैं!
क्या आपने इसे हल किया? – benoffi7
@ benoffi7 हां, जवाब ने मेरी समस्या हल की। – csharpbd
