Aranet4 Time Series Export (Part 1): Scan + Pair

Pair and read an Aranet4 on Linux

Unblock Bluetooth (rfkill)

rfkill list
sudo rfkill unblock bluetooth
rfkill list

Proceed only when Bluetooth shows Soft blocked: no and Hard blocked: no.

---

1) Create a dedicated uv project for Aranet4 tools

Use a clean folder so the dependency and lockfile stay isolated.

mkdir -p ~/dev/aranet4
cd ~/dev/aranet4
uv init --python 3.11
uv add aranet4

---

2) Scan with aranetctl (first attempt)

Run the scan from your uv environment:

uv run aranetctl --scan

If the scan finds your device, copy the MAC and read it:

uv run aranetctl AA:BB:CC:DD:EE:FF

---

3) If aranetctl --scan fails, pair/trust with bluetoothctl, then retry aranetctl

1. Start bluetoothctl:

bluetoothctl

2. Enable the adapter and pairing agent:

power on

3. Scan to discover the Aranet4 MAC:

scan on

4. Pair with the device (use the MAC you see in scan output):

pair AA:BB:CC:DD:EE:FF

5. When prompted, read the pairing code shown on the Aranet4 screen and enter it in bluetoothctl.

6. Trust the device:

trust AA:BB:CC:DD:EE:FF

7. Exit:

scan off
quit

8. Retry from the ~/dev/aranet4 folder:

cd ~/dev/aranet4
uv run aranetctl --scan
uv run aranetctl AA:BB:CC:DD:EE:FF
