NRF2460 is linked，but is mute

[snowstone]

NRF2460 is linked，I can transfer 3 byte data. But sometimes it is mute, not always. Register I2SCNF_OUT bit6 is zero.

I am appreciate for your advices.

The nRF2460 will automatically mute if the audio buffer is about to underrun. It is recommended to use the maximum TXLAT setting 0x06.

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.

hi,Thanks a lot for your reply. I set TXLAT value is 0x06, AND I use IIC interface to w/r NRF2460, Can you give me any advice more?

Can you try to add a 100us delay between I2C bytes (for testing)?

Let me have a test. Thank you very much.
