Ketika saya menjalankan hcitool scan
shell show Scanning...
selama ~ 10 detik tetapi tidak menunjukkan hasil apa pun.
Sama untuk sudo hcitool scan
(Saya memiliki ponsel Android dan PC terdekat dengan bluetooth diaktifkan dan diatur ke terlihat)
(Itu berhasil pertama kali; saya tidak mengubah apa pun sejak itu)
Spesifikasi Sistem

Saya berlari hcidump --raw
dan alat pindai menemukan semua perangkat bluetooth terdekat. Ini dumpnya (saya memindai dua kali):
