CHIRP

Hi,

When I try to download configuration from radio-walky, more or less at middle of process I get the following message:

"Radio sent incomplete block xxxxxx" (where xxxxxx are a hexadecimal memory address -I suppose-)

If I try to upload a pre-existent configuration to radio, in the same way, more or less at middle of process I get the following message:

"Radio refused to accept block xxxxxx" (where xxxxxx are a hexadecimal memory address -I suppose-)

Environmento:

Radio: Baofeng uv 5r
Radio Firmware (pressing key 3 while switching ON): BFB297
CHIRP Version: Daily-20170627 (periodically and correctly updated from official CHIRP PPA-repository)
GTK: 2.24.30
PyGTK: 2.24.0I'
Pyton: 2.7.12
Computer Operating System: Ubuntu Linux 16.04-1 64Bits
Kernel: 4.4.0-83

Cable used: Standard USB to radio cable.

I'm exclusive linux user, so have not access to windows environment. Anyway, I've tried to send and receive data from radio using different radio software like GNUAis, JWX, JNX... and it works (I use the same exact cable).

Any help or suggestion to help me?.

Thank you in advance.
