1. use send_c_store to send CT Image Storage
2. dicom file is stored successfully, but the cstore scu did not receive successful response
3. the package I captured use wireshark show the P-DATA Command has mistake as above

Can you post your code and the output from debug_logger(), please?

from pynetdicom import debug_logger

debug_logger()

# ... your code

Can you also attach the dataset you're trying to send, or if that's not possible can you confirm that it's readable using pydicom:

from pydicom import dcmread

ds = dcmread("path/to/dataset")
print(ds)

I resolved it . default transfer_syntax is DeflatedExplicitVRLittleEndian, but scp dose not support it, I use transfer_syntax=[ImplicitVRLittleEndian, ExplicitVRLittleEndian] ,then it work. Thanks for you!
