Hello, My name is Scott and am new to the list. I am currently
attempting to use obexftp (and hopefully later obexfs) to move files
between an Android device (Android 7.1.1) and a device using
openembedded Linux (Ettus E312). I am attempting to use USB Bluetooth
Dongles (have tried both Broadcom BCM2072A0 chips and CSR chips) with
the same results. I am currently able to push a file from the Linux
device to the Android device, but cannot move anything from the Android
device to the Linux device (either pulling from Linux device or pushing
from Android device). Any help/advice is much appreciated!
