About I3C ENTDAA ,How to do End DAA procedure waveform?

[CLHUANG]

hi

I do the ENTDAA protocol use this code

if (HAL_I3C_Ctrl_DynAddrAssign_IT(&hi3c1, 0) != HAL_OK)

{

/* Error_Handler() function is called when error occurs. */

Error_Handler();

}

In below picture , I get the ENTDAA Protocol, but After protocol there should be repect start and do End DAA procedure waveform. It always keep  ,pull up high after a few seconds.(ref three pic.

How can I do it?End DAA procedure waveform

Below picture is all protocol , no End DAA procedure waveform

YES , it work

I change one sensor ,   it solved

I change jumpper on X-NUCLEO-IKS01A3 board

after ,it protocol is the same .

thank you very much.

Why can't multiple devices generate this protocol?

The ENTDAA  not supported with the LPS22HH ( see datasheet ).
You need to use another way using SETDASA .
