Mengirim gambar melalui bluetooth dari PC ke ponsel

Bluetooth API – adalah ide yang bagus
Anda dapat menggunakan langkah selanjutnya:
1. Enum layanan telepon yang tersedia dengan fungsi WSALookupServiceBegin, WSALookupServiceNext
2. Dapatkan alamat layanan Transfer File OBEX
3. Buat soket bluetooth
4. Hubungkan ke alamat layanan yang ditemukan
5. Menerapkan protokol Transfer File OBEX (perintah Hubungkan dan Pasang – http://netwinder.osuosl.org/pub/netwinder/docs/nw/irda/IrOBEX12.pdf[^], http://dotcom.bluetoothsig.org/SiteCollectionDocuments/GOEP_SPEC_V12.pdf[^]) dan mengirim file melalui soket
Saya dapat membagikan proyek pengujian sendiri, tetapi tidak tahu cara melampirkannya ke solusi
