kandi X-RAY | connectivity-samples Summary

connectivity-samples is a Java library typically used in Networking applications. connectivity-samples has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. However connectivity-samples build file is not available. You can download it from GitHub.

This repository contains a set of individual Android Studio projects to help you get started writing Connectivity apps in Android. If you find an issue or bug in one of the projects, feel free to file an issue on this repository with the following information: - The specific project that pertains to the issue (for example: the BluetoothLeGatt project) - Steps to repro the issue, including the API version and Android device model. Example of a good issue: In the BluetoothLeGatt sample, I am unable to see any BLE devices after the initial scan. I ran the sample on a Pixel 2 running API version 28. Examples of bad issues: 1. Bluetooth scanning doesn’t work. 2. My app is crashing when I try to send a large file. 3. How can I support BLE in my app?. Requests for samples related to Android connectivity are also welcome.

Android-BLE - Problems writing data to Characteristic

QUESTION

How do I get the raw bytes received in from BLE in the android BLE sample program?

Asked 2021-Jun-15 at 04:38

I am using the BluetoothLeGatt example from here: https://github.com/android/connectivity-samples/tree/master/BluetoothLeGatt

Assume BLE connection, service and characteristic detection have all happened properly. The following data being sent is value of a characteristic.

From a custom BLE device, I am sending an array of bytes to the smartphone, for example, something line {0x00, 0x01, 0x02, 0x03, 0x04}. In the android program this is received inside the onReceive() function inside BroadcastReceiver mGattUpdateReceiver in DeviceControlActivity.java

The line

The example you are using receives the data as a byte array already, but it appends hex representation to the data as string. This is why you get your data in both representations.

You will need to change the example in the file BluetoothLeService.java on line 149. It is currently reading
intent.putExtra(EXTRA_DATA, new String(data) + "\n" + stringBuilder.toString());

and you would need to change it to
intent.putExtra(EXTRA_DATA, new String(data) + "\n");

if you want to receive only the string representation.

QUESTION

Why Google Nearby Connections needs ACCESS_COARSE_LOCATION and/or ACCESS_FINE_LOCATION permissions?

Asked 2020-Sep-30 at 17:38

I googled very hard and still no explanations "why?" these permissions are needed to establish offline(no internet) connection between devices. I have simple app that requires only p2p-star strategy to exchange data between devices in master-slave pattern and I have troubles explaining to my users why my app needs them. "Just because lib said so. That's why".

Official documentation also said nothing to me.

"A primary goal of this API is to provide a platform that is simple, reliable, and performant. Under the hood, the API uses a combination of Bluetooth, BLE, and Wifi hotspots, leveraging the strengths of each while circumventing their respective weaknesses. This effectively abstracts the vagaries of Bluetooth and Wifi across a range of Android OS versions and hardware, allowing developers to focus on the features that matter to their users."

PS: as I know ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION are about GPS

Because Bluetooth and WiFi scans can reveal the user's location, either as an approximation ("Family Room TV" was discovered, so you must be home) or in detail (Device A, B, and C were last seen at lat/lng X, so we think you're probably at X).

Android-BLE - Problems writing data to Characteristic

Asked 2020-Apr-09 at 07:22

I'm trying to write data to a BLE-characteristic, but I got the status 130 in my callback what means GATT_WRONG_STATE. Unfortunately, I have no idea, what state is wrong and how I can change this.

I'm using the BLE-App from the Android-connectivity samples (https://github.com/android/connectivity-samples/tree/master/BluetoothLeGatt) with minor changes so far.

Here's my DeviceControlActivity:

To use reliable writes, the characteristic properties must include the reliable writes bit. Your characteristic doesn't, so simply use "normal" writes instead.
