RIL

XDA Developers,
Years ago I downloaded the RIL .dll and API from this site. Then it was only half complete and I had to patch it my self.
I am sure development has been completed since then.
Can anybody tell me if RIL is still maintained by this site? In which case, where can I get it?
Specifically I need signal quality on XDA II upwards. If anybody can help me?
Kind Regards,
Ben

After posting, my text RIL was shown with a link to most of the information.
There is one think I can't understand. The stucture returned as as follows:
int nMinSignalStrength; // @field TBD
int nMaxSignalStrength; // @field TBD
int nLowSignalStrength; // @field TBD
int nHighSignalStrength; // @field TBD
Which have the values (On XDA IIs) of -113, -51, -110, -60
Would any member know what the meaning of these values is?
I have then tried to convert the quality to a percentage. But the percentage always reads way to high, or zero.
My guess is that these are DB and therefore logarithmic. Would any member know how to convert to a linar scale?
My guess is something like: log10(n / 3) where n is any of the above or retuned figure.
Any ideas would be very useful!
Regards, Ben.

Hi,
Code:
HRESULT RIL_GetSignalQuality(
HRIL hRil // @parm handle to RIL instance returned by <f RIL_Initialize>
);
returns the following structure:
Code:
typedef struct rilsignalquality_tag {
DWORD cbSize; // @field structure size in bytes
DWORD dwParams; // @field indicates valid parameters
int nSignalStrength; // @field TBD
int nMinSignalStrength; // @field TBD
int nMaxSignalStrength; // @field TBD
DWORD dwBitErrorRate; // @field bit error rate in 1/100 of a percent
int nLowSignalStrength; // @field TBD
int nHighSignalStrength; // @field TBD
} RILSIGNALQUALITY, *LPRILSIGNALQUALITY;
Why don't you just use nSignalStrength? Sounds pretty simple and linear to me? Nothing to calculate...

In trying to make my posting simple. I think I forgot to clarify my problem
First is the problem that the nSignalStrength falls between two values.
But there are two fields it can fall between:
nMinSignalStrength <= nSignalStrength <= nMaxSignalStrength
nLowSignalStrength <= nSignalStrength <= nHighSignalStrength
Which one should be used? Why are there two?
Secondly, I want to show a percentage result between one of the above. But these figures are, I belive, Decibels (BD). Each 3 DB = a doubling of the value. So 1 = 10%, 4 = 20%, 7 = 40% etc...
Therefore a liniar percent placement of nSignalStrengh tells me nothing. Most values are close to Max, and then suddenly zero.
My math is a little rusty I was hoping somebody may have a nice function for returning the linear range from the logarithmic rage….
Thanks again to any members who can offer some help
Ben

Hmm... but what if min and max are just values currently encountered in your local cell? When you move to another cell you may receive different min/max values. Or maybe these are the values of the farest and nearest cell? I don't know either, but your explanation of min/max sounds worse to me than does mine...

This could be correct. The values I have are on my XDA IIs using O2 are:
Min -113
Low -110
High -60
Max -51
Therefore:
Min < Low < nSignalStrength < High < Max
So I am using Low = 0% and High = 100%. But this returnes figures of above 50% when signal is quite low.
I think the linear conversion is exp(value / 3)
Therefore percent is:
percent = (exp(nSignalStrength / 3) - exp(Low / 3)) / (exp(high / 3) - exp(Low / 3)) * 100;
Which seems to give better figures. But I am not sure how accurate it is..
Any experts on signal quality out there, I'd love to hear from them!
Ben

If anybody is following this thread, this *seems* to return a good percentage for signal quality. I am not sure of the quality or accuracy. But it works
static double dValue, dMax;
dValue = (int)data->nSignalStrength; // (int) to convert twos complement signed integer correctly.
dMax = (int)data->nHighSignalStrength; // (int) to convert twos complement signed integer correctly.
dValue -= (int)data->nLowSignalStrength;
dMax -= (int)data->nLowSignalStrength;
dValue = pow(dValue / -3.0, 2);
dMax = pow(dMax / -3.0, 2);
dValue /= dMax;
dValue *= 100;
if (dValue > 100) dValue = 100; // never
if (dValue < 0) dValue = 0; // never

Ben

Hi there, i've been following this thread with interest I have a very limited knowlege of C++ but not even on the PPC.
Would you mind attaching or even PMing your cpp so i could possibly learn more ?
I find i learn more by examples, and am quite interested in making an application that can disable the radio then re-enable it after a set ammount of time (so i can swap between sims, i have a dual sim adapter)

Best thing to do is follow the sample code supplied by these nice gues from xda-developers, by clicking on this RIL link.
BUT replace the ril.h in the .zip archive with the ril.h you will find from the link.
(nb: if the author of this .zip archive is reading, it's way out of date to the ril.h on this site. ps, hows the ril development going?)
If you get the sample code working, this will give you some idea of what is possible. Your options may not be possible. But look at the ril.h and the functions listed. If one of them does what you want, give it a go.
Regards,
Ben

volume setting

I am trying to set the volume to my needs then put it back after. I have use the code from ppc developer network and when that did not set the correct volume I also did the registry as well. Don't worry about "reg", its my registry class and it works fine.
DWORD oldReg=0;
oldReg=reg->readDWORDfromReg(name,path);
reg->saveDWORDtoRegistry(name,path,0xffffffff);
WAVEFORMATEX wf;
wf.wFormatTag = WAVE_FORMAT_PCM;
wf.nChannels = 1;
wf.nSamplesPerSec = 8000 * 1000;
wf.wBitsPerSample = 8;
wf.nBlockAlign = wf.nChannels * wf.wBitsPerSample / 8;
wf.nAvgBytesPerSec = wf.nSamplesPerSec * wf.nBlockAlign;
wf.cbSize = 0;
HWAVEOUT hwo;
DWORD dwVolume=0xffffffff;
DWORD oldVolume=0;
int waveDevice=-1;
UINT numberOfDevices=waveOutGetNumDevs();
for(UINT id=0;id<numberOfDevices;id++)
{
if (waveOutOpen(&hwo,id,&wf,0,0,CALLBACK_NULL)==MMSYSERR_NOERROR)
{
waveDevice=id;
waveOutGetVolume(hwo,&oldVolume);
waveOutSetVolume(hwo,dwVolume);
waveOutClose(hwo);
break;
}
}
.........playing sound here all ok....
//put the volume back
if(waveDevice!=-1)
{
if (waveOutOpen(&hwo, waveDevice, &wf, 0, 0, CALLBACK_NULL) == MMSYSERR_NOERROR)
{
waveOutSetVolume(hwo, oldVolume);
waveOutClose(hwo);
}
}
reg->saveDWORDtoRegistry(name,path,oldReg);
I can set the volume to any value below the origional volume but any attempt to set a volume higher just dose nothing. There are no errors (checking left out here), just the same level. I did not seriously expect the registry part to work as I guess there is some event to trigger that change, but others seem to get results from waveOutSetVolume.

Well, I never tried changing volume by code, but I know TCPMP player does it well and it's open source so might be worth taking a look at.

Thanks levenum, I will give it a look.

Before I got a chance to look at that code I got a result. I have been using PlaySound to play a resource with no volume change working. When I use waveOutWrite to play a buffer containing the same data I can get the volume change I am after. There is still something wrong with my code because the sound gets garbled but I think I will figure that part out. I also want to next test playsound with a file instead of a resource.
<edit>
using playsound with the same file plays clear sound but the volume change is not working. Its a pity because to get the waveoutwrite to work properly i had to fill in the WAVEFORMATEX with the CORRECT values. This means that if I am allowing the user to specify files to play I will have to find out the samples per second and bits per sample info before I can use the file.

HTC - 6 Tab Home PlugIn & Customization

Again the idea was to have all the registry setting ready after a Hard-Reset or a ROM-Flash. The last two months I have made my Cruise a ROM lab testing every ROM I found to this FANTASTIC Forum.
And I'm very happy that I have a PDA that can be customizable.
So here is the cab ...
http://www.turboupload.com/download/00pEcIE03vrj/HTC_6TabHomePlugIn.cab
It contains:

Removed "HKLM\Software\OEM\MASD\Quickdial"

[GUIDE] How to change speaker or microphone gain manually

WARNING
i'm not responsible for any damage to your speakerphone, headset, or anything else. try this method with your own risk.
Click to expand...
Click to collapse
hello, this is my first thread on XDA and i will explain how to change audio input/output configuration on galaxy note 2 (based on my experience, and it works perfectly!)
YOU ONLY NEED:
1. a rooted note2
2. root explorer
Let's get started!
1. open root explorer
2. search 'default_gain.conf' at root /system/etc/ (if you can't find this file, sorry, i don't know anymore )
3. mount R/W
4. hold the file until there's an option 'open in Text Editor', click
5. here you will see a tons of audio configuration
TO HEAR THE DIFFERENCE, YOU'LL NEED TO REBOOT YOUR PHONE! (not soft reboot)
#Output Modifier Stage
output i mean speaker, headphone, etc
There's 4 mode configuration for output audio gain
Normal, Incall, Ringtone, Incommunication
Incall is audio config while you in call
Ringtone is audio config for ringtones
Normal is all media sounds that plays on your device (except above)
Incommunication --> dunno
this is audio config for earpiece in normal mode
Code:
#Output Modifier Stage
#Normal, Incall, Ringtone, Incommunication
#Modifier: Normal
Modifier "Normal" {
SupportedDevice {
"Earpiece"
}
Enable {
"Earpiece" for Earpiece
"Speaker" for Loudspeaker
"Headset Out" for Headphone
if you wan't to increase or decrease the gain volume, just change the "..... Volume", ... },
Example, i want to increase my speaker volume, change that number (followed with blue color):
Code:
Modifier "Normal" {
SupportedDevice {
"Speaker"
}
Enable {
{ "AIF1DAC1 Volume", 96 },
{ "AIF1 Boost Volume", 0 },
{ "DAC1 Volume", 96 },
{ "SPKL DAC1 Volume", 1 },
{ "SPKR DAC1 Volume", 1 },
{ "Speaker Mixer Volume", 3 },
{ "Speaker Boost Volume", 4 },
{ "Speaker Volume", [B][SIZE="5"][COLOR="Blue"]58[/COLOR][/SIZE][/B]},
}
if you want to increase your headset volume, just find "Headphone Volume" and change it.
if you want to increase your earpiece volume, just find "Earpiece Volume" and change it.
#Input Modifier Stage
input i mean microphone
you need to scroll down almost half of the page to find the microphone configuration until you find this:
Code:
#INPUT Modifier Stage
#Voice, Camcorder, Recognition, Communication,
Modifier "Voice" {
SupportedDevice {
"Builtin Mic"
}
Enable {
There's 4 mode for input modifier stage
Voice is for recording voice
Camcorder is for recording videos
Recognition is for voice recognition like google now, voice search, etc
Communication is config while you in call
"Builtin Mic" is microphone that located on the bottom of the phone
"Back Mic" is microphone that located on the top of the phone
"Headset In" is microphone from your headset
What is this?
Code:
{ "AIF1ADC1 HPF Mode", 2 },
{ "AIF1ADC1 HPF Switch", 1 },
HPF is High Pass Filter that will filter your audio
HPF Switch
0 = disable (and of course it will no differences if you change the mode)
1 = enable
HPF Mode
change this mode between 0-2, you will notice the different.
as my experience changing this mode,
0 = low frequency strong, high frequency poor
1 = low frequency and high frequency balanced
2 = low frequency poor, high frequency strong
now, to change the gain, you only need to change this:
"IN2L Volume" or "IN2R Volume"
example, i want to decrease the audio gain of my builtin microphone for recording audio, change the number that follows with blue color:
Code:
Modifier "Voice" {
SupportedDevice {
"Builtin Mic"
}
Enable {
{ "AIF1ADC1 HPF Mode", 2 },
{ "AIF1ADC1 HPF Switch", 1 },
{ "IN2L Volume", [SIZE="5"][COLOR="Blue"][B]16[/B][/COLOR][/SIZE] },
{ "MIXINL IN2L Volume", 0 },
{ "AIF1ADC1 Volume", 96 },
}
if you want to change the audio gain for recording videos, scroll down again until you find the "#Camcorder" section. It's same method with the "Voice".
after you finished editing, press back and 'YES' to save it. it will automaticaly backup the older 'default_gain.conf' with ".bak" file.
so if you accidentialy forget the default configuration, just delete the 'default_gain.conf' and rename the 'default_gain.conf.bak' to 'default_gain.conf'
don't forget to reboot your phone to notice the different! (not soft reboot)
good luck!

another possibility is to use a kernel with boeffla sound, agni kernel for example

yeah i've tested agni kernel but some tweaks can't be changed with agni. example they say "microphone sensitivity" and it only change the headset input gain.
so i edit the 'default_gain.conf' and trying to change the builtin mic gain, and it perfectly works

File missing
Hi,
My GN2 runs latest PA with stock PA kernel and I cannot find the default_gain.conf file. Do I have to use some specific kernel or what could be the problem?
Thanks
Leo

Hi
Do you know how to make 'privacy mode' so when you plug in your headset the speakers are off (ringtone/notifications etc) without flashing Agni kernel?
Thanks

Simple Hacks for Lollipop-Sense Based ROMs

Want BoomSound? What about Harman/Kardon?
These hacks are very simple to do. Just simple changes to files.
>>insert non-responsibility disclaimer here...<<

I have tested most of them, but not all, hence you will see that some of them are questions (in red). I didn't bother changing those ones as to me personally either not necessary or didn't want to mess. But I included them anyways.
Tried and tested that the hacks will be implemented upon factory reset. Have not tested if restarting will work.
Just restart the phone for the changes to be applied.
Requirements:
Root (obviously)

As you can see, upon opening the file/s, there are a lot of things that can be changed. Thread accordingly when changing things.
The reason above for the "your_file" is that depending on what base ROM you've got (eu, asia, wwe, etc) plus the combination of the sim card that you've got, the phone will try to find the corresponding xml file. I will let you figure this one out. But it is very easy to do. This could also be the reason why that you might need to factory reset your phone before these hacks will work.
I would recommend, as much as you can, to use the right file. In any case, remove the unnecessary xml files but keep the "default" one. Your phone will use it then.
Upon changing the values on the files, you must make sure that the permissions of them are set back to normal. Too lazy to say.
I bet these hacks can also easily be implemented by the Xposed Modules, avoiding the need for factory reset.

For the telephony 5G I'm pretty sure that may enable the use of 5GHz for the wifi hotspot/tethering, as it currently only uses the 2.4GHz wifi. Might be best to not fiddle with quick boot as I heard that's incompatible with Lollipop.

I've thought the same. But I think it is already enabled even though the file is saying not. Don't have a 5ghz wifi to test.
