    Hi,

    This behavior is most likely due to the connection lost by the passive. The passive device does not really participate to the connection (the passive device only listen the master and the slave - the passive cannot ask the master/slave to re-send the date). As a result, the passive device can easily lost the connection, especially in a noisy environment.

    The work around is not implemented by TI but consists in resetting and re-connecting the passive device when the connection is dropped (Note: to re-connect the passive device, the master device has to re-transmit the connection parameters to the passive).

    I hope this will help,

    Kind regards,

    Hi,

    I still think you are missing some packets due to the normal packet loss. Try to run conductive tests and/or to implement the "reconnection" feature I described in my previous answer. 

    For the rest, you can consult this app-note and this link to get more data about AOA accuracy.

    I hope this will help,

    Best regards,
