No More Signal Anxiety.
Your Car, Your Control.
PNX (Phone · Near · eXecute) redefines BLE keyless entry: phone proximity auto-verifies identity; near-field range auto-confirms; then you press the micro-switch to unlock. No false triggers, no lockouts — certainty in your hands.
What PNX Brings
We don't dismiss any technology — we offer a more controllable, more reliable choice within the BLE ecosystem
Deterministic Control
Verification completes automatically, execution is triggered by you. No more relying on signal "luck" — every unlock is your active choice, free from waiting and anxiety.
Low-Cost Upgrade
Built on standard BLE 5.x protocol, no special hardware needed — ESP32 is enough to get started. OBD power, ten-minute installation, bringing digital key experience to legacy vehicles.
Open Collaboration
Open technical standard, complete protocol documentation, open-source reference implementation. Developers, solution providers, and automakers are all welcome to shape the future of BLE digital keys together.
PNX Three-Layer Decoupled Architecture
Verification completes automatically, execution triggers manually — signal fluctuations no longer affect the final outcome
Phone Verification
The phone serves as a digital identity token. Once Bluetooth connection is established, the module verifies identity via UUID, confirming "you are an authorized user."
- Completed seamlessly, no need to take out phone
- Supports 8-10 UUID whitelist entries
- Typical duration: 1-3 seconds
Proximity Confirmation
Distance is determined via Bluetooth RSSI signal strength. Only when entering the preset threshold range does the system determine the user is "present."
- Unlock threshold: recommended -65dBm
- Lock threshold: recommended -80dBm
- Hysteresis protection prevents repeated toggling
Manual Execution
With both verification and confirmation complete automatically, execution control is handed to the user. Press the micro-switch, and the system sends the unlock command.
- Typical delay: ≤ 200ms
- Does not rely on sustained RSSI stability
- User retains final control authority

Every legacy vehicle deserves an upgrade. PNX, based on BLE low-power Bluetooth, enables digital key functionality without replacing the vehicle. Through retrofit solutions, give older cars a new experience and reduce premature scrapping due to outdated features.
BLE modules consume ultra-low power — standby current under 10mA, with negligible impact on the vehicle battery. Choosing PNX means choosing a more sustainable way to move.
