I have a prototype board with nRF5340 and the audio amplifier device &quot;https://www.ti.com/product/TAS6584-Q1&quot; that uses i2s for streamingen-USTelligent Community 13Thu, 14 Nov 2024 20:49:54 GMThttps://devzone.nordicsemi.com/thread/510568?ContentTypeID=1Thu, 14 Nov 2024 20:49:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b7f704d3-d863-44e1-ae8d-dccd3c8c53b5Jagadeep Ram<p>I have fixed the problem by creating two tasks, One for BLE, where the BLE is initialized and advertised and other is for i2s streaming. The BLE task is set to higher priority than the stream.</p> <p></p> <p>I&#39;m able to see BLE notifications as well as streaming working together without any issue.</p> <p></p> <p>Thank you.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/507528?ContentTypeID=1Wed, 23 Oct 2024 09:12:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dca20f6c-d02c-4bd8-8371-b3f588ff9ae7Sigurd<p>Hi!</p> [quote user=""]Looks like the BLE characteristics can not be written while the main function is having an infinite loop with no sleep time.
