I had test with BlueSoleil, and 'Object Push & File Transfer' work well.
However, there is another problem with BS, I think.
Searching my phone device, which was unpaired with my PC, was OK.
After that, I clicked the Finish button then it asked PIN code to me on my phone device.
That was OK.
After I inserted PIN code on my phone device, BTF shows me the 'general failure Error'.
When I used Mircrosoft driver, the driver also asked me the PIN code on my PC after having inserted PIN code on my phone device, and Connection & Pair were complete.
But BS driver did not, and Connection & Pair were failed. General failure Error.
After I paired with my phone device by hand, File Transfer worked well.
Could you test it?
