# 1 Reason: could not connected ![](images/1+Reason_+could+not+connected_2f56140c.jpg) 如果测试遇到该问题,麻烦贴一下上面的截图,并且请帮忙指出上图红色框里面对应的信息: 1.Found by EID at xxxxxx, xxxxx对应的地址是什么 2.手机端显示connecting对应的时间点 3.手机端显示Test finished对应的时间点 \ log分析: ![](images/1+Reason_+could+not+connected_fd12c263.jpg) 截图位置1: "Found by AK at 48:48:6A:60:5A:F7" 截图位置2: "Scaning by EID" "Found by EID at 7B:F8:BE:9E:64:E0" 截图位置3: 手机尝试connecting 7B:F8:BE:9E:64:E0 但是此时耳机端因为 48:48:6A:60:5A:F7 这条link还没有断掉 手机再尝试连7B:F8:BE:9E:64:E0的时候 耳机端会认为link已经存在,直接拒绝这次连线 导致手机端测试显示 "Could not connect" 这个问题不是必现的 \ 想请问是不是可以先断开48:48:6A:60:5A:F7这条link,确保手机和耳机的link断开之后, 再尝试执行截图位置2以及之后的操作? 不然的话, 如果在48:48:6A:60:5A:F7这条link 断开之后, 再scan 到7B:F8:BE:9E:64:E0 并且尝试创建BLE link 是没有问题的。 如果在48:48:6A:60:5A:F7这条link 尚未断开之前 ,就scan 到7B:F8:BE:9E:64:E0 并且尝试创建BLE link, 就会遇到上面描述的问题。 \ log: 0006294 03-28#14:18:17.958 199 0034334.679 \[HCI\] hci_if_confirm: buf 0x0020de33\ 0006295 03-28#14:18:17.958 200 0034334.980 \[HCI\] !!!hci_le_conn_cmpl_evt: handle 0x0015, peer_addr 75 F2 05 93 E8 62 connection already exist\ 0006296 03-28#14:18:17.958 201 0034335.049 \[HCI\] !\*\*hci_cmd_disconnect: handle 0x0015, cause 0x13\ 0006297 03-28#14:18:17.958 202 0034335.183 \[HCI\] hci_if_write: buf 0x00407397, len 7\ 0006298 03-28#14:18:17.958 203 0034335.299 File\[011\], Line\[0239\] \[MODULE_LOWERSTACK\] \[clk:0x0001acd2\]--\>HCI_CMD:opcode:0406 len:3, 15001300-00407440-00130011-000d0004-00800000\ 0006299 03-28#14:18:17.958 204 0034335.343 File\[011\], Line\[0789\] \[MODULE_LOWERSTACK\] DISCONNECT OPCODE\ 0006300 03-28#14:18:17.958 205 0034335.390 File\[201\], Line\[2466\] \[MODULE_LOWERSTACK\] \[LL\] Disconnect Cmd: conn_handle 21 entry 10 reason 13 COM3_btsnoop_2023-03-28_14-17-41.cfa COM3_2023-03-28_14-17-31.log air_log_could_not_connect.btt bugreport-taimen-RP1A.201005.004.A1-2023-03-28-14-19-27.zip 这个问题需要咨询google: from google: Thanks for reporting. I found a race condition which can lead to this result. I'll prepare a fix, but since it does not reproduce on devices that we have, and to save some time, I would like to share an APK with the fix with you to verify it resolves the issue. Can you provide a Google account on which I can share the APK once it is ready? google 提供的新的apk: validator_realtek_diag.apk Alice Zhou(周丽) 麻烦用这个apk压测试试看,是否还能复现到这个问题 \
