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?

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?
Is it possible to color the cells in the grid view? If yes..
View 2 Replies View RelatedI 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?

But I cannot seem to remove the spacing between the buttons in the Table.Setting pading to zero for the buttons has no effect.

View 4 Replies View RelatedI 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?
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.
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 ?
I'm trying to determine location via bluetooth beacons and while I can discover and find all of the devices around me, when I try to grab the EXTRA_RSSI that's supposed to come through it doesn't work.

I am having this issue where I am trying to have a single TextView span one to two lines, fill the cell completely (so you can also click edges of the cell and it will trigger) and center-align.
This is the layout for the cell:
CODE:...
However cells seems to be filled correctly ONLY if it happens to wrap around and end up spanning two lines of text. It shows center-aligned and you can click anywhere in the cell to trigger the click. The cells that do not span multiple lines of text are left-aligned and trigger (highlight) only if you click where the text is. There is a "numb" area which does not react to clicks inside the cell if the text is short.

This weekend im going to be installing 2 antennas i ordered from wi-ex one is for 1X signal and the other is for 3G when pointing them im gonna be inside the house looking at the dBm while a friend is on the roof so i can try to get them both peaked i know when i go into test mode ##program and on the HDR Status Screen this is the 3G reception info but my question is which one should i be looking at the HDR RSSI or the Receive Power im thinking its the RSSI but i wanna be sure also the lower that number the better right? and for the 1X signal i goto the Call Processing Status Screen and look at the RSSI.
View 3 Replies View RelatedI'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?

View 4 Replies View RelatedI'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.

I just can't figure this out. All I need to do is be able to make calls to other cells and landline phones over my wifi connection using my incredible ( i don't get cell service at home). No international calls. I have sip set up and fring. I can dial out on my dinc and i will hear ringing but but that is it. No one picks up. I have called my home phone and it doesn't ring.

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.
View 1 Replies View RelatedI'm writing an android application that collects cell signal strengths.I am having trouble getting the "current" cell signal strength, but I don't have any problem getting the "neighboring" cell signal strengths.To get the current cell signal strength, I created a PhoneStateListener and implemented the onSignalStrengthChanged callback.It works, but not very well.It seems like the signal strength hardly ever changes, and resolution jumps to only a few numbers.I would accept the answer that the resolution of the signal strength hardware is coarse, but when I use the TelephonyManager's getNeighboringCellInfo() method, it works much better.The signal strength readings from neighboring cells change frequently, and they have much better resolution.So, how can I get the current cell signal strength in the same way that I am getting the neighboring cell strengths?It seems odd to me that the functionality of the neighboring cells is better than the current cell.

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.
