Hi,

The constant BLE_EVT_DATA_LENGTH_CHANGED only exist for SD API v3, thus it fails when referenced for SD API v2. You can fix this by commented out these lines of code: https://github.com/NordicSemiconductor/pc-ble-driver-py/pull/117/commits/62445e12ba60f0ecb609db585c4f36229859d8fc. This fix have also been merged with the pc-ble-driver-py master branch now.
