I am appreciate for your advices.en-USTelligent Community 13Mon, 19 Dec 2016 03:10:37 GMThttps://devzone.nordicsemi.com/thread/70731?ContentTypeID=1Mon, 19 Dec 2016 03:10:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2a51d811-aee6-4fec-ba3e-27850de3688dsnowstone<p>Let me have a test.

I set TXLAT value is 0x06, AND I use IIC interface to w/r NRF2460, Can you give me any advice more?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/70728?ContentTypeID=1Mon, 12 Dec 2016 09:46:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:19461767-1524-4253-b7dc-3608661623ddKenneth<p>The nRF2460 will automatically mute if the audio buffer is about to underrun. It is recommended to use the maximum TXLAT setting 0x06.</p> <p>If mute occurs in specific when host MCU write/read data to the nRF2460, then make sure that you meet the serial timing requirements. For instance for SPI there should be a minimum of 500us delay after CSN go low, between SPI bytes, and after CSN go high again.</p><div style="clear:both;"></div>
