Bluetooth eMA511-client python application

In my project we are using CA-SDK BOARD MPU9250. To begin, we launched the python application eMA511-client, that worked very well, we could pick up information we needed as quat, gyro and so on. However we would like now to use bluetooh connection, but is it possible to use it with this application? Because a password for the connection is asked while we didn't set any password.. And if we set a password we don't have any possibility to connect the device to the computer.

Thank you for reading and helping ...
