Direct ENET cable connection from the OBD port to your Android device. Your device must run the Android 6.0.1 version minimum to support ethernet connectivity.

...

Newer phones (e.g. Samsung S20) have a USB-C connector at the bottom for charging. In this case, you need an Ethernet to USB-C adapter. BELKIN usbUSB-c to ethernet adapters work works great.

Older phones, provided they have Ethernet connectivity support (Android 6.0.1 and higher), will need an Ethernet to microUSB adapter to connect to the charging port on your phone/tablet. Pluggable brand carries a microUSB to Ethernet adapter that will work in this case.

...

Android OS (all versions) turns off your Internet (mobile data) connection the moment you plug in the ENET cable or connect to the BM3_NET WiFi network. This is unfortunate default Android behaviourbehavior. iOS keeps the internet just like Windows and macOS and even though all computers should behave this way, Android does not (blue star)

...

In case your Android device is older and doesn’t have this setting you will, unfortunately, need to fall back to using Offline Mode instead.

Other options are try upgrading your Android OS or more costly but very convenient, just get an iPhone (smile)

Direct ENET Cable Connection - Ethernet Settings (Android 6.0.1 - Android 10)

Here are the Ethernet settings to configure on your Android 6.0.1 - Android 10 device for proper connectivity. This is a one-time configuration:

ENET cable MUST be connected to your Android device to see the Ethernet menu under settings and configure them.

Info

Ensure that the Ethernet setting shows DISCONNECTED. If showing connected, you won’t be able to update the settings below until you tap the toggle button to disconnect.

  1. Go to Settings → Connections → More connection settings → Ethernet → Configure Ethernet device

  2. Change from DHCP to Static IP (click on Static IP)

  3. Enter the following IP settings:

    1. IP address: 169.254.250.250

    2. Netmask: 255.255.0.0

    3. DNS address: 0.0.0.0

    4. Default gateway: 0.0.0.0

  4. Hit ‘Save’ at the bottom.

  5. When back on the Ethernet screen, toggle the Ethernet button to the right (to connect).

At this point, your Android device is configured for Ethernet with the vehicle. Go back to the bootmod3 app and you should see the vehicle’s VIN showing.

Info

If VIN doesn’t show, double-check the above settings and ensure Ethernet is turned ON.

Note

Some rebranded generic ENET WiFi adapters alter the vehicle’s IP configuration from default. These settings will reset after the vehicle sleeps for at least 20-30 minutes. To avoid waiting that long and have it reset the vehicle’s network configuration, disconnect the ground wire on the vehicle’s battery for 3 minutes and reconnect it.

These settings DO NOT seem work on Android 11 as tested on Samsung S20 Ultra running latest Android update at this time (Feb 2nd 2021). For Android 11 Ethernet-USB connectivity see section above.

Ensure your BM3 WiFi Adapter is running the latest Standard edition firmware on the device’s SD card, instructions here:

...

In case you have an older device that is running an earlier version of Android than 6.0.1, or you’d simply like to use a wireless connection with your BM3 WiFi Adapter, follow these instructions to set up your WiFi settings on your phone. This is a one-time configuration:

  1. Power on the BM3 WiFi Adapter box

  2. Wait for the BM3_NET Wifi network to show up among your available networks, but DO NOT connect to it right away! Click on the ‘gear’ icon on the right and configure its IP settings first.

    1. IP address: 169.254.250.250

    2. Gateway: 0.0.0.0

    4. Subnet (if showing): 255.255.0.0

    5. Network Prefix Length (if showing): 16 <---- CHANGE FROM 24 to 16!

    6. Click on ‘Save’

At this point, your Android device is configured for Ethernet with the vehicle. Go back to the bootmod3 app and you should see the vehicle’s VIN showing.

Info

If VIN doesn’t show, double-check the connection to the BM3_NET WiFi network and IP settings are correct.

Note

Some rebranded generic ENET WiFi adapters alter the vehicle’s IP configuration from default. These settings will reset after the vehicle sleeps for at least 20-30 minutes. To avoid waiting that long and have it reset vehicle’s network configuration, disconnect the ground wire on the vehicle’s battery for 3 minutes and reconnect it.
