 ====== Using OsmAnd on a motorbike ======
-In this article I write some notes about using and **Android** device (actually a **smartphone**) as a **GPS navigation system on a motorbike**. The choosen software is **[[https://osmand.net/|OsmAnd]]**; a mature and full-featured navigation system based on the **[[https://www.openstreetmap.org/about|OpenStreetMap]]** geographic data. I tested two different smartphones: a **[[..:hardware:zte_blade_a610|ZTE Blade A610]]** and an **[[..:hardware:oukitel_wp12|Oukitel WP12]]**.

The choosen software is **[[https://osmand.net/|OsmAnd]]**; a mature and full-featured navigation system based on the **[[https://www.openstreetmap.org/about|OpenStreetMap]]** geographic data.

+===== Mounting =====
+First of all, it is necessary to make a premise: I usually travel at very low speeds, hardly exceeding **90 km/h**. My bike, despite being a **650 cc twin cylinder**, has few vibrations and I only occasionally drive on dirt roads. Here I tell you what is my setup, which is working well for my needs, but you must adapt the mounting to your specific scenario.
+I provided both the smartphones with a **flexible TPU cover**. The ZTE is quite **thin**, so it is blocked firmly by the holder without any additional precautions. Instead the Oukitel is **thick and heavy** enough that the gaff clips on the phone holder do not tighten it sufficiently.
+FIXME
+===== Waterproof =====
+The **Blade A610** is not waterproof, so it can only be used when the weather is nice.
+Instead the **WP12** is rated as **[[wp>IP_code|IP68]]**, i.e. it should be **dust-proof** and it should resist even to **immersion into water** at 1 meter depth. However, the water resistance of the WP12 is ensured by **a rubber flap protecting the power connector**, so it is not possible to keep the smartphone charging when it rains.

+===== The charging cable =====
+=== 12V power charger ===
+=== Magnetic connector ===
+To keep the ZTE permanently connected to the **charging cable**, I purchased a **micro-USB magnetic adapter** (specifically a **NetDot 10th Gen**). The magnetic adapter is quite convenient to plug/unplug the power connector even wearing gloves and it prevents damages if you inadvertently pull the cable.

+In the photo above you can see two adapters: one fitted into the phone connector and the one that I carry with me as a **spare part**. I used just a bit of silicone adhesive to make the plug more stable and to prevent dust from entering. It turned out that the magnetic coupling is quite **strong and stable** to resist to vibrations and wind. You must pay attention to avoid dust into the electric contacts, which are rather delicate and can actract **ferromagnetic dust**.

 {{.:osmand:osmand-screen-brightness.jpg?400|Screen brightness: ZTE Blade A610 vs Oukitel WP12}}
+The **Oukitel WP12** is advertised for a brightness of **350 cd/m²**, while the BV5300 is advertised for **500 cd/m²**. I think that the Blackview is largerly overstimated; comparing the screen brightness at full white I measured an **increased brightness of a bare 8%**.
