wireless transfer

I attached a screenshot of a wireshark capture which shows shows a small part of the PTP/IP protocol in action. Due to a limitation in wireshark, it's not possible to dump the decoded packets to a new pcap file. A CSV, TXT, or JSON file is possible though for those interested.

In the complete capture, the DHCP request and offering is also visible. The 192.168.1.2 is the Leica M10 camera which acts as the server.

Brilliant!  So, it's PTP/IP.  That's relatively understood protocol--good news.  The DHCP sequence sounds a little bit more tricky.  Let me get this straight...the camera is acting as a DHCP server and the iPhone gets an IP from it on a 192.168.1/24 subnet, and then, presumably, the app initiates PTP/IP with the phone?

 

I'm impressed that Wireshark has a PTP decoder.

You're correct on the DHCP part. Perhaps the DHCP responds has specific options for the phone (app) for connecting.

Wireshark recognizes the PTP/IP protocol, but not sure if it can also extract transported images. I did do a quick search to find out if there are any (opensource/cross-platform) PTP/IP clients available, but not much luck on that front.
