Serial port used: /dev/dongle
Traceback (most recent call last):

raise NordicSemiException('Failed to {}. Error code: {}'.format(wrapped.__name__, err_code))
pc_ble_driver_py.exceptions.NordicSemiException: Failed to open. Error code: 13
Error code 13 means #define EACCES 13 /* Permission denied */ but the device is read/write accessible to all:
Where is the permission problem?
/dev/dongle points to the DK J-Link:
ls -ald /dev/dongle
lrwxrwxrwx 1 root root 7 Jun 29 22:55 /dev/dongle -> ttyACM0
and opens/scans/discovers fine with the C examples.
(I used 115200 baud.)
edit: I just noticed there are two different connectivity firmwares with pc-ble-driver-linux and pc-ble-driver-py package:
nrf51-ble-driver_linux_0.5.0/firmware/connectivity_115k2_with_s130_1.0.0.hex
/usr/local/lib/python2.7/dist-packages/pc_ble_driver_py/hex/connectivity_115k2_with_s130_2.0.1.hex
Does the python driver need 2.0.1 and the Linux/C driver need 1.0.0?
I would like to use C and python applications.
