        I am testing the range between two iot747 devices,

        I am tryign with LE Unicast UTXV and UTXM,

        At a certain distance the audio stream is down but when I decrease the distance between the two devices the audio stream doesn’t recover,

        I am not receiving any error message on the terminal and if I write STATUS on both devices I get that they are still connected,

        Is there anyway to fix this issue, basically either get a notification so I can close and reopen the connection or an automatic reconnect.

        config on initiator:

        config
        AUDIO=0 0
        AUDIO_ANALOG=9 15 1 OFF
        AUDIO_DIGITAL=0 44100 64 00100100 00000000

          Hi,

          I tested and I do get:

          CLOSE_OK 14 BLE 245DFC021572
          LC3_VOICE_STOP 19
          CLOSE_OK 19 UTXV 245DFC021572

          On both sides when I have a Link Loss.

          Can you recheck that you don’t get this?

              Hi,

              Thank you for your reply,
              I was on an old firmware version, I tested it on v3.1.70, I am getting notifications on link loss,

              But is there a way both devices can reconnect automatically,
              Let me explain more my setup so I am connecting only two devices using Unicast UTXM bidirectional audio stream (I am using gaming mode),
              and I want this to be a reliable robust connection and I need it to reconnect in case of link loss,

              Any suggestion?

              Thank you,
              Abdo

              Hi,
              For now, you would need to reopen the connection from the transmitter when you see a CLOSE notification.
