Hi Behcet and Dan, There is a v2 of the DPP specification. The only difference is that Wi-Fi Alliance has a adopted the program name for the specification rather than DPP. So the reference would be Wi-Fi Easy Connect Specification v2.0.
You can find the document here: https://www.wi-fi.org/download.php?file=/sites/default/files/private/Wi-Fi_Easy_Connect_Specification_v2.0.pdf Cheers, Mike On Fri, Aug 19, 2022 at 11:23 AM Behcet Sarikaya <sarikaya2...@gmail.com> wrote: > Hi Dan, > > > On Thu, Aug 18, 2022 at 9:54 AM Dan Harkins <dhark...@lounge.org> wrote: > >> >> Hi Behcet, >> >> On 8/17/22 2:36 PM, Behcet Sarikaya wrote: >> >> Hi Peter, >> >> I quickly read this short document and have some comments. >> >> In the informative references section, DPP is listed as Device >> Provisioning Profile while it should be Device Provisioning Protocol. >> Actually, in the acronyms section the name is correctly given.
