Hi, I have a AX210, which has BT5.2 features, so I want to play music by le audio cis, but when I register endpoints, it fails. log is like this: root@zz-HP-ProBook-650-G1:/home/zz/project/bluez-5.70# hciconfig hci0: Type: Primary Bus: USB BD Address: F4:7B:09:F8:74:4B ACL MTU: 1021:4 SCO MTU: 96:6 UP RUNNING RX bytes:20036 acl:0 sco:0 events:2934 errors:0 TX bytes:698026 acl:0 sco:0 commands:2912 errors:0 root@zz-HP-ProBook-650-G1:/home/zz/project/bluez-5.70# hciconfig hci0 up root@zz-HP-ProBook-650-G1:/home/zz/project/bluez-5.70# bluetoothctl Agent registered [bluetooth]# power on Changing power on succeeded [bluetooth]# advertise on hci0 advertising_added: instance 1 [CHG] Controller F4:7B:09:F8:74:4B SupportedInstances: 0x07 (7) [CHG] Controller F4:7B:09:F8:74:4B ActiveInstances: 0x01 (1) Advertising object registered Tx Power: off Name: off Appearance: off Discoverable: on RSI: on [bluetooth]# endpoint.register 00002bc9-0000-1000-8000-00805f9b34fb 0x06 [/local/endpoint/ep0] Auto Accept (yes/no): y [/local/endpoint/ep0] Max Transports (auto/value): a [/local/endpoint/ep0] CIG (auto/value): a [/local/endpoint/ep0] CIS (auto/value): a Failed register endpoint Here is my compile method: 1. change main.conf followed https://www.bluez.org/le-audio-support/ 2. ./configure --prefix=/usr --mandir=/usr/share/man --sysconfdir=/etc --localstatedir=/var 3. make && make install So, would you please give me some hints to solve this problem? Thanks. Best regards, Wendy
