I bought Yuntab Bluetooth Smart Jogging Watch U8 from Amazon. The printed directions say to download an APK from an IP address with FTP:
thufir@doge:~/.bluetooth$
thufir@doge:~/.bluetooth$ ftp 120.24.66.245
Connected to 120.24.66.245.
220 (vsFTPd 3.0.2)
Name (120.24.66.245:thufir): anonymous
331 Please specify the password.
Password:
530 Login incorrect.
Login failed.
ftp> exit
221 Goodbye.
thufir@doge:~/.bluetooth$
The directions don't specify a user or password.
How do I get the app?
