How to decode npdsch.pcap?

[liuwei-network]

Issue Description

Hi! I followed this tutorial (https://docs.srsran.com/projects/4g/en/latest/app_notes/source/nbiot/source/index.html) to set up a NB-IoT testbed. But I cannot decode npdsch.pcap with wireshark. I found this pcap is with DLT 147, but this tutorial(https://docs.srsran.com/projects/4g/en/latest/usermanuals/source/srsue/source/2_ue_getstarted.html?highlight=pcap#observing-results) didn't cover 147. How should I config my wireshark to decode the pcap? This is an example pcap. And I confirmed that it worked well with srsGUI.

Thanks in advance!

Hi @VLiu7,

If you go _Preferences > Protocols > DLTUSER

You can add an entry with the following details for DLT=147 to correctly decode the pcap:
