i2s residual current consumption after playing a song

[Sébastien Despont]

Hello,

I am using i2s through the driver : "nrf_drv_i2s". After playing a song, I have a residual current consumption about 1mA unless I call nrf_drv_i2s_uninit every times after stopping a song.

Is it a normal behavior?

Thanks

Yes, I can verify that I get the same ~1mA current consumption here as well. The I2S peripheral will continue to consume current if it is not turned off after use. Use NRF_I2S->ENABLE = 0; or the uninit function if you are using the SDK driver.

I am using SDK11. Do you know if this bug is also existing in SDK 12.X?

You still have to do it in SDK 12.
