General description

After selecting a remote Bluetooth device this app can perform two tests.

Ping test

This device opens a RFCOMM Bluetooth connection to the server on the other device and sends successive packets to the other device, which echoes the packets back to this device.

This test requires that the other device also has the BtPing installed and that it\'s running.

An alternative is to roll your own ping server listening with the standard RFCOMM UUID 00001101-0000-1000-8000-00805F9B34FB and have it simply echo back everything it receives. The remote device in this case need not be an Android device.

The number of roundtrips and bits transferred per second (the sum of transmit and receive rates) is measured and displayed once per second during the run and the average values after the run has ended.

RSSI measurement

The second test is the measurement of the received signal strength indication (https://en.wikipedia.org/wiki/Received_signal_strength_indication">RSSI). This test can be performed on any Bluetooth device, as long as it\'s discoverable.

If the other device has BtPing installed, you can use it to make the device discoverable.

Privacy and advertising

I am very sensitive to privacy issues in this increasingly intrusive world.

Thus this app only requests permissions that are absolutely necessary for the correct functioning of the app.

The app does not collect any personal information, does not collect any usage statistics and does not send any information anywhere.

The app does not and never will include any form of advertising.

Bug reports and feature suggestions

Please feel free to jan.kalin@gmail.com">report any bugs that you may encounter.

Also feel free to suggest features that you would like to see in a future version of the app.

I will take time to read your mail, but I cannot promise an immediate response, as I have a daytime job, a baby and have developed this app primarily for my own use.
