How do I read the (write) data sent by the "on_write" interrupt from Centoral?
If you have a sample program Please.

The program I created is described below. Please point out any mistakes.
-------------------------------------
if (p_evt_write->handle == p_cus->cus_value_sts_handles.value_handle)
{
cus_Sts.len = p_evt_write ->len;
memcpy(cus_Sts.dat, p_evt_write ->data, cus_Sts.len);
}
-------------------------------------
It seems that you misunderstand the description method, but I'm not sure, so please point it out.
Also, please let me know if there are any parameters to enable in the initial settings.
Thank you

Hello,

I don't see any obvious problems with the code posted. Does the program reach the memcpy() line if you write to this handle?

Best regards,

Currently, there is no central side, so the operation cannot be confirmed.
There was a comment that I thought was a sample program, so I referred to it.
There is no sample program that clearly describes how to read the data "write" by central.
Is it okay to judge that the program described in the previous question is correct?
Thank you

You can use nRF connect on Android/iOS to test your implementation.
