Baby Monitor All-in-One Licensing

The most extended model for this kind of apps is "per user".

What does it mean? Very simple: if you have 2 Android devices with the same Google account that you used to buy the app you don't need to buy a second license. If the 2 devices use different Google accounts then yes, you need 2 different licenses.

Some users said that simply adding as a second Google account the one used to by the app on a second device, the app can work with a single license. A small group couldn't... and finally a small part of them needed to reset the terminal after this test (depending on device model).

This license model is also used by Apple at their AppStore.

How can I improve Bluetooth range of my Baby Monitor?

The Bluetooth technology was designed to make wireless connections over short distances between portable devices. The class implemented in our devices by manufacturers has a maximum range of 10-15 meters with no obstacles in between.

From an article published at ehow.com we can consider the following points to improve our Bluetooth connection:

• Minimize as many large obstacles as possible between the Bluetooth-connected devices. Range improves if, for example, there are fewer walls between the devices. Range also is affected by large furniture between devices, so move the electronics or rearrange furniture to improve performance.
  
• Turn off or move away from competing wireless signals, such as Wi-Fi connections. Wi-Fi works like Bluetooth, but is much stronger. The signals can disrupt Bluetooth connections, shortening the Bluetooth's range.
