Android :: How To Get Bluetooth RSSI On Android After Discovery

Jun 8, 2010

I'm trying to write a program that can read the signal strength of a bluetooth device linked to my android 2.0 handset. Doesnt seem like android exposes anyway to get the RSSI unless it is during discovery. Is there any other way to get the signal strength of the device after the device has been detected? I read of a way to do it using NDK to access the underlying BlueZ API, but I dont know how to use that. Any help would be appreciated.

Android : How To Discovery A Bluetooth Headset

Aug 17, 2010

I write a sample code to discovery a Bluetooth headset(jabra BT2035). referece http://developer.android.com/guide/topics/wireless/bluetooth.html#DiscoveringDevices

But it can only discovery my notebook computer. If my notebook computer enables Bluetooth and sets Enabling discoverability.

The SDK document snippet:

android.bluetooth.device.action.FOUND"
public static final String ACTION_FOUND
Since: API Level 5
Broadcast Action: Remote device discovered.
Sent when a remote device is found during discovery. I think the remote device means a remote notebook computer except a Bluetooth headset. Could someone please help with this?

Android :: Get RSSI - To Get Bluetooth Signal Strength

Jan 27, 2010

I am working on Android platform 2.1 and trying to make an app that can get the Bluetooth signal strength from remote devices. It seems i should try to read the 'RSSI'

something like : int rssi = intent.getIntExtra (BluetoothDevice.EXTRA_RSSI, Integer.MIN_VALUE);

But it just keep returning the latter default value.

Did anyone ever manage to get the value of RSSI? Do we need to pair the device before getting the RSSI?

Android :: How Do I Poll RSSI Value Of An Existing Bluetooth Connection?

Jan 27, 2010

I need to know the signal strength of a Bluetooth connection to a remote device that I make with my Android 2.1 phone. From the SDK, I can see that I can determine the RSSI at the time I discover the remote device. But I can't see how to update that RSSI value over time.
Can someone give me a hand?

Android :: Android IRC Office Hours - Android Bluetooth RSSI

Jan 27, 2010

I have a question about bluetooth RSSI functionality on the Android (either 2.0 or 2.1):

It's easy enough to get the RSSI value when a bluetooth connection is created, but how can you repeatedly get the RSSI value of a connection that is already active? It's really important to be able to do this, because this lets you determine if bluetooth devices are close to each other or far away, but I can't find any appropriate function calls in the Android API.

Android : Delete Discovery Channel App?

Jan 20, 2010

Sometime yesterday Discovery Channel announced the availability of their application for Android. Has anyone been able to find it? Following the link provided in their official twitter feed led me to a 404, and Marketplace searches yield nothing for me. I'm on Droid Eris.

Discovery Channel Launches Android App - AppScout

Even the QR code I found here yields nothing:

Android :: WifiManager.calculateSignalLevel - RSSI 5

May 20, 2010

I am trying to use the Wifimanager to calculate the Signal Level of the access points found during a scan.

I am using the following method:

WifiManager.calculateSignalLevel(int, int)

But it appears to always return the same int no matter what the RSSI level is.

Here is my code:.............

The logging outputs 1 for all the test cases for calculateQoS(int).

Am I missing something simple here? Why is the SignalLevel always 1?

Android :: Get RSSI In GSM Cells / Way Or Class Available?

May 7, 2010

I´m trying to get the rssi value from the main cell i´m currently connected to in an application for Android 1.6. I´m using android.telephony.gsm.GsmCellLocation which does not have this value. For Android 2.1 its avaible android.telephony.SignalStrength, but I cannot find anything equivalent for API 4. Is there any other way or class available?

Android :: Cell RSSI - Network Signal Strength - On 1.5

Feb 16, 2010

Is there any way to retrieve the current cellular Signal Strength (RSSI) on Android 1.5?

I know there's a way to listen for signal strength updates through the TelephonyManager, but this seems to only give a "state," not a numeric value.

Is using the RSSI field on a neighboring cell fairly accurate? I'm guessing not, but I'm running out of ideas.

Android :: UMTS Signal Strength - RSCP Or RSSI

Sep 27, 2010

I need some clarification on API docs.

http://developer.android.com/reference/android/telephony/SignalStreng... getSignalStrength() indicates: "Get the GSM Signal Strength, valid values are (0-31, 99) as defined in TS 27.007 8.5"

[url] getRSSI() indicates "received signal strength or UNKNOWN_RSSI if unknown For GSM, it is in "asu" ranging from 0 to 31 (dBm = -113 + 2*asu) 0 means "-113 dBm or less" and 31 means "-51 dBm or greater" For UMTS, it is the Level index of CPICH RSCP defined in TS 25.125"

So, for 3G UMTS networks, does the SignalStrength class not return the same value as the NeighboringCellInfo class ? What are the chances that each RIL implementation is sending something different ?

Has anyone see negative value for signalStrength on UMTS networks as is possible for RSCP index values ?

Android :: Why Would JmDNS Service Discovery Work On Motorola Droid Running Android 2.1

May 1, 2010

I have successfully gotten JmDNS working on Android 2.1 testing on a Motorola Droid by using MulticastLock, but recently got an HTC Incredible as second test device, and JmDNS discovery doesn't work at all.I should mention that broadcasting a service still works and everything appears to run normally, but serviceAdded never gets called. Does anyone have thoughts on why this might be?

HTC Incredible :: Accidental Discovery Camera

May 11, 2010

I remember reading that you could touch the screen to show the camera where you wished it to focus. I was trying that and in holding the focus spot on the screen after a second or so the camera snapped the shot. No push of track thingy. Replicated. Did I just miss this info? I was really surprised. For me, this makes the shot really steady and clear.

Motorola Droid :: Interesting Discovery About Soft Keyboard

Nov 10, 2009

There has been a lot of discussion on Engadget about whether the soft keyboard has multi-touch. Engadget insists no, and Rob here insists yes.I think I discovered where the problem lies. Josh at Engadget was saying that you had to release one key before pressing another or they would not both register. Rob said in his review that you COULD press them at the same time and both would register. I think I found out that both are right.I did some experimenting and would love to see whether others come to the same conclusion. It seems that when the keys are far enough apart (more than a couple of keys away), then you can, indeed, press the second before the first is released and they both register.BUT, if the keys are close to each other, it will not do this. You have to release one key before pressing the other.I think this must be to avoid accidentally hitting two keys with one finger.So, whether you think this is a good feature or too much babysitting of our typing abilities, it does seem intentional.

RSSI - Application To Read Signal Strength Of 3G / GSM / WiFi

Mar 17, 2009

I'm developing an application to read signal strength of 3G, GSM, Wifi.

Is there any classes that provides us with the RSSI of 3G signal and GSM signal?

The WifiManager Class provides the RSSI for wifi, but I can't find any for 3G and GSM. If there is no classes provided, is it difficult to start from scratch?

Sprint HTC Hero :: Accidently Removed Bluetooth Software That Allows To Connect Stereo Bluetooth Headsets

Mar 13, 2010

I was cleaning all the crap off my phone I don't use anymore and I believe I accidently removed the bluetooth software that allows it to connect to stereo bluetooth headsets. I can control the player with the headset, I can make phone calls from it, but when I try to play music there is no sound.

I was trying to reset the phone using RUU, but it reboots the phone and then says it cannot reconnect after that and the software shuts down. I can still sync with outlook, so my driver is not the issue. I am out of ideas.

Is there anyway possible to reinstall just the bluetooth portion of the rom?

HTC Desire :: Bluetooth - Trying To Send Contacts Over Bluetooth From Old Sony Ericsson

Nov 19, 2010

This is my first android phone and im having some problems with the bluetooth. Im trying to send my contacts over bluetooth from my old sony ericsson but it doesnt seem to be going smoothly, i would say its all down to me! Basically i have got the bluetooth on for both phones, the desire is set to be discoverable and i try to send the contacts via bluetooth on the SE. I get the whole passcode and accept the file which i have done, but then it says again about accepting the file. Ive tried it a few times and i have 3 bluetooth icons at the top of my screen now which i imagine are for transferring files which need accepting. Is there anywhere i can to accept them or close them down?

Android :: How To Run Bluetooth Pen?

Nov 10, 2010

I have a Fascinate. A lot of my colleges are starting to use iPad tablets to take notes in them with a stylus in lieu of paper. I have also seen pens out there that record pen strokes as you write on paper and will show it on your PC once you sync it later. I was hoping that there is a Bluetooth pen that I could connect with my Fascinate and have an application running on the phone that would record the pen strokes in the app whether I'm writing on a piece of paper, or on the desk, or where ever... I know the screen would be too small to actually write on the phone but I would think the technology exists to record pen strokes in an app. It would be nice to have one very portable device that could take notes in and have the ability to email it from the phone or sync it to my PC and print/email from there if needed. We have been moving all of our filing to PDFs to save on paper and this would just be another digital move and a way to back up all of the paper notes that we take in internal meetings, etc.
