Hi,

I found the option to Build -> Show Build Log in Segger emStudio. I'm posting the content of the log below. Is that what you were asking for? Did you also see my update below? Could you provide any hints how to solve this?

RE: Sending I2S data via BLE using queue

user113261 — Mon, 13 Jun 2022 09:07:41 GMT

Hi Kazi, thank you for your reply. I'm quite new to Segger emStudio and programming the nRF - is there a tutorial on how to debug into the preprocessor symbols and where can I access the proprocessor logs? I didn't find any information about that on the internet.

For clarification: the nRF is advertising and I can connect to it. The problem starts when I enable notifications and the code, thereby, enters the if-clause in line 46 in my main function (i2s_transfer becomes true).

Hello,

Could you please debug into the preprocessor symbols and check the log to see where the error is? You can send the log to us.

Thanks.

Best Regards,

Kazi Afroza Sultana
