I2S BCLK will not output continuously without datahttps://devzone.nordicsemi.com/f/nordic-q-a/121970/i2s-bclk-will-not-output-continuously-without-dataThe BCLK_CONT option to i2s_configure() is not being honored anywhere. How do I get BCLK to output continuously without having to do i2s_write() or i2s_read() calls over and over?en-USTelligent Community 13Tue, 17 Jun 2025 02:10:51 GMTRE: I2S BCLK will not output continuously without datahttps://devzone.nordicsemi.com/thread/539462?ContentTypeID=1Tue, 17 Jun 2025 02:10:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:88bae196-2142-4942-af09-e386c484cddcTerence Kim<p>OK - it sounds to me then that I have no choice but to serve up buffers via i2s_read/write repeatedly to keep the MCK signal outputting.
