Unable to sync with device

[grafoteka]

Hello, I'm trying to use this ESPROS package. Before I could use successfully the oficial rosserial with an Arduino Leonardo. But with this package I'm having the following error:

[ERROR] [1593536893.001784]: Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino

I'm using ROS Kinetic with Ubuntu 16.04. The port is not blocked.

crwxrwxrwx 1 root dialout 188, 1 jun 30 19:11 /dev/ttyUSB1

I'm trying to use the chatter example, but I'm stack at this point.

Kinds regards, Jorge
