From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx> The code was stopping at first time it detected an unknown TLV type when it could continue: > HCI Event: Vendor (0xff) plen 82 Vendor Prefix (0x8780) Intel Extended Telemetry (0x03) Extended event type (0x01): Audio Link Quality Report Type (0x05) Unknown extended subevent 0x81 01 01 05 81 04 88 13 00 00 82 10 6a e6 6c 00 00 ...........j.l.. 00 00 00 4b 45 53 00 00 00 00 00 83 04 00 00 00 ...KES.......... 00 84 04 01 03 07 19 85 04 3f 08 00 00 86 08 00 .........?...... 00 00 00 00 00 00 00 87 04 00 00 00 00 88 04 00 ................ 00 00 00 89 04 00 00 00 00 8a 04 b9 49 0c 00 ............I..
