[http_transport]: Waiting for authentication token. E (17198) [dspg_utility]: Trigger Acoustic model was not successfully uploaded 0 E (17228) [dspg_utility]: No Clock in TDM0 pin - Try number 0其中 可以發現 dspg_utility 的報錯日志

2. Audio ES8311 無法正常工作

• I2S 工作正常
• I2C Read Data NO ACK 情況　i2c信號的ACK與NACK

3. ESP32 AWS IOT Connect Fail

4. ESP32 燒錄工具的使用

• 使用的燒錄工具為V3.6.6

• Also there seems to be a <new_line> at the end of your client ID. Can you remove that and try?
• This current client ID might be too long.

由于device.info 中多了一行導致的異常，正常如下 :

修改這種配置文件，用vim打開保存之后會修改之前的格式，建議用VS Code修改

• GPIO 異常
