Preceeding the IETF there will be a hackathon from 2021-11-01 to -05 (Monday to Friday).
Projects during the hackathon are typically organized along IETF protocols and not along operating systems, but I still think it’d be nice to see where RIOT winds up there.
Myself I’ll join the Group OSCORE and EDHOC projects (starting Wednesday); my stuff won’t be based on RIOT, but I’m happy to give a hand here or there.
Do you participate in hackathon projects where RIOT is used?
