Hi everyone,
I’m working with three nRF9151 DKs to evaluate DECT NR+, and I’m trying to understand what level of multi‑hop or mesh networking support currently exists in modem firmware mfw‑nr+_nrf91x1_2.0.0 (MAC+PHY).
Point‑to‑point communication is already working using the hello_dect sample (NCS v3.3.0‑preview2).
Setup
- Hardware: 3× nRF9151 DKs
- SDK: nRF Connect SDK v3.3.0‑preview2
- Modem Firmware: mfw‑nr+_nrf91x1_2.0.0 (MAC+PHY)
- Sample Used:
hello_dectPHY sample (point‑to‑point is working)
What I Want to Build
A simple 3‑node chain:
[Leaf 1 (PT)] 
[Relay / Router (FT)] [Leaf 2 (PT)]
The FT node should receive traffic from PT‑1 and forward it to PT‑2.
My Questions
1. Is multi‑hop or mesh supported today?
- Does the current DECT NR+ MAC layer provide relay, forwarding, or multi‑hop capabilities?
- Or is the expectation that all forwarding logic is implemented at the application level?
2. Future support
- Is mesh or multi‑hop routing on the roadmap for DECT NR+ on the nRF91x1 platform?
3. How should addressing and forwarding be handled?
If multi‑hop must be done manually:
- What is the recommended way for the FT to map packets between PT‑1 and PT‑2?
- Should routing be based on:
- Short Addresses?
- Link‑local IPv6 addresses?
- Does the MAC API provide any discovery or routing helpers?
If anyone has experience with DECT NR+ multi‑hop or knows the firmware capabilities/limitations, I’d really appreciate your insights.
Thanks!
