how to correctly display a list of bluetooth devices

Asked 2019-Jun-19 at 16:14

I have an activity where I would like to show a list of both paired and unpaired bluetooth devices. I don't want a button that just shows the list, but the list is shown directly. I'm following the example of the android guides https://github.com/googlesamples/android-BluetoothChat/blob/master/Application/src/main/java/com/example/android/bluetoothchat/DeviceListActivity.java but I can't understand why the unpaired devices don't appear in the list, while the already paired devices appear correctly in the list.

Transmit data from smartwatch to smartphone over bluetooth

Asked 2018-Jan-26 at 20:28

I need some help for data transmission between Android Wear and Android phone. I found some tutorials and sample code, so I could make a framework. Much of my code is similar to the Android open source sample, https://github.com/googlesamples/android-BluetoothChat. But my question is, if devices are already paired, do I need them all? In other words, my Android Wear watch and Android phone are already paired, can data transfer be much simpler? Or do each application using Bluetooth need everything from above sample code? Anyone who has this kind of experience of knows useful samples, please help me!

Thank you in advance!

If your devices are already paired you don't have to set up the Bluetooth connection yourself. You can simply use the Data Layer API to synchronize and send data between the wearable and the phone.

Android phone and bluetooth device communication error

Asked 2017-Dec-07 at 23:39

I am modifying an Android bluetooth sample program to realise the communication between my android phone and an ELM327 module through Bluetooth.

The application is build from the program using Android studio. The application works very well between two android phones.

However, when I run it in one of my android phone and try to communicate with ELM327 module, the input messages coming from ELM327 are broken and some time has very serious delay. Could you please explain why the different apperances happen? If you can help to rectify the program, it will be really appreciated.

Below is part of the sample code for this application:

I am working on the project on the android dev. the website for BluetoothChat and it seems to be sending messages correctly but not receiving them. In the past, I attempted to create another Bluetooth app and when connecting to a device I was prompted to confirm the connection and presented with a pin code. when working on the current app I am never given a prompt. However, it is not hitting any exceptions and messages seem to be sending. Here is my Thread class for managing a connection:

Get tank volume with ODBII in android

Asked 2017-Oct-10 at 16:04

I want to receive the remaining tank volume and the current mileage of my car by using OBD II.

Therefore I have bought an OBDII Bluetooth Adapter for my car. I am using the AndroidBluetoothChat for connecting to devices and establishing a connection, through I can send and receive information.

But when I try to connect to my OBD2 Adapter, I get: Unable to connect. The OBD2 Adapter is always discoverable and I can pair them normally. Why is that?

The next question is, once i have established a connection, how can I receive Informationen like speed, mileage etc.

I am still a beginner and gratefull for every hint.

ANSWER

Answered 2017-Oct-10 at 16:04

i'm in your same project :D I start with BluetoothChat for understand how use Bluetooth and all works fine.... At the beginning you can chat with your OBD by sending Pids in the EditText from BluetoothChat...

But remember that you need a \r (carriage return) after every commands that you send. For example if you need the RPM, send a string like "010c\r" and you get a response like 10c410cxx where xx is the value that you must divide by 4 for get the real RMP... See every pids and data transformation in this table...

REMEMBER that for work the ELM327 (your obd device) need that the car is ON half turn key or total or you don't get data but only error!

For the pids that you need (if your car support them) you can see all of them in the wikipedia page that i liked.

If you want an automatic dynamic comunication with obd you must change the comunication of the BluetoothChat with some Queue or ArrayList of commands and send them continuosly.....

REMEMBER that the ELM327 can manage one command each time....so send the first command and wait the response... and again send another command an wait response...and so on...

Sending an APK via Bluetooth to another device

Asked 2017-Aug-29 at 09:46

I´m trying to develop an App which can send an .APK file via Bluetooth to another device with an Insecure Rfcomm connection. I´m running self-coded apps on both devices. The apps are not the same but I can still set the UUID, Rfcomm Listener and so on, so the connection should work fine and because of the insecure rfcomm without any alert to accept the transfer. I´ve tried the BluetoothChat example from the Android developer page, but I´ve got problems with changing the code for my purposes. Can anyone give me some snippets of code or any link to an tutorial how to setup Apps for Bluetooth File transfer? Every useful stuff is welcome.

EDIT: You could say I´m trying to develop an app, which can "update" another app on another phone by Bluetooth.

Thanks

When you received the message on on BluetoothChatService, Broadcast the received message using local broadcast , And receive the message on the Activity which you need using Broadcast receiver.
