LoRa P2P (Peer-to-Peer) Mode
LoRa P2P communication mode and direct edge gateway integrations (such as HARDWARIO FIBER) are introduced in upcoming platform firmware releases.
LoRa P2P (Peer-to-Peer) allows STICKER devices to transmit proprietary, unmanaged radio frames directly to other nodes or edge receivers without connecting to a LoRaWAN Network Server (LNS).
Key Advantages
- Zero Network Server Infrastructure: Operates without requiring cloud or local LoRaWAN Network Servers (ChirpStack, TTS).
- Low Latency & Custom Schedules: Direct transmission without network join negotiations or LNS duty-cycle overhead.
- Standalone Edge Gateways: Ideal for pairing directly with HARDWARIO FIBER or custom edge receivers in remote or air-gapped deployments.
- Power Efficiency: Eliminates downlink listening windows and join request retries when out of network coverage.
Architecture & Topology
In LoRa P2P mode, STICKER bypasses the LoRaWAN MAC layer while utilizing the underlying Semtech SX1262 / STM32WL LoRa PHY modulation layer.

Radio Parameters
When operating in P2P mode, both the transmitter and receiver must be configured with matching physical RF parameters:
| Parameter | Default Value | Description |
|---|---|---|
| Frequency | 868.100 MHz (EU868) / 915.000 MHz (US915) | Center RF frequency channel. |
| Bandwidth (BW) | 125 kHz | Channel bandwidth. |
| Spreading Factor (SF) | SF7 | Trade-off between link budget/range and airtime (SF7 to SF12). |
| Coding Rate (CR) | 4/5 | Forward error correction scheme. |
| Preamble Length | 8 symbols | Radio frame synchronization preamble. |
| Sync Word | 0x12 (Private) | PHY sync word used to isolate private P2P traffic. |
| Tx Power | +14 dBm | Output RF transmission power. |
Configuration & Management
P2P parameters and radio modes can be set locally over NFC using HARDWARIO Manager or via the developer RTT shell:
config radio-mode p2p
config p2p-frequency 868100000
config p2p-sf 7
config p2p-bandwidth 125
