Original question:

CC2640R2F: AoA Angle is not fixed in rtls_example.py

CC2640R2F: AoA: rtls_aoa_iq_log.py returned key error

Hi, 

Please see the log below, while running rtls_aoa_iq_log.py, it returned a key error.

The master found the slave and then it exited.

Would you give your comments? Thanks!

    I've found the cause which is that master_node.rtls.connect and set_ble_conn_info have wrong parameters in SDK release.

    Oh, thank you very much. Btw I'v already installed the new version of SDK and it works properly however your solution may be useful for others as I found many unresolved problems with this case.

    Best regards,
