RIL Library not provided by quectel

sudarshan · July 17, 2020, 1:36pm

Hi,

We Added RIL library provided by the quectel team to our Android 9.0 and we compiled.

Then we checked whether library is loaded or not, with command given in user guide.

It is loaded according to document.

Then we checked version of library loaded, but it is printing nothing.(According to document if nothing prints, then library not given by quectel team)

Can you suggest me how to overcome this problem.

RIL Library loaded

iwg34m_8mm:/ # cat /init*.rc | grep ril-daemon
service ril-daemon /vendor/bin/hw/rild -l /vendor/lib64/libreference-ril.so

Version of RIL library

iwg34m_8mm:/ # getprop gsm.version.ril-impl

iwg34m_8mm:/ #
iwg34m_8mm:/ #

Do you get any reault by using

getprop | grep ril

Did you set:

vendor.rild.libargs 
vendor.rild.libpath

You should have some similar to:

it depends on your Build Structure, you need to add multiple Parameters.
lemme show your my way to do it:

i placed all my stuff in /vendor/quectel/ec25

vendor/quectel/ec25$ cat BoardConfigPartial.mk

BUILD_WITH_EC25 := true

Hi,

Thank you for valuable support.
I did the changes as your instruction, and it is worked for me.

sudarshan · July 23, 2020, 7:00am

Hi,

Thank you for valuable support.
I did the changes as your instruction and it is worked for me.

We tested call feature with quectel 4G module.
We are able to call and able to receive the call but not audible.

Can you suggest me the implementation procedure for voice over a USB.
Also, we are interested to test GPS in android with Quectel 4G module.
Can you please share the GPS related libraries and implementation procedure.

Thank You,
Regards,
Sudarshan

tcandroid291.apk · July 23, 2020, 10:56am

Hi Sudarshan,

for GPS you need to add GNSS HAL to manifest.xml

 <hal format="hidl">
        <name>android.hardware.gnss</name>
        <transport>hwbinder</transport>
        <version>1.0</version>
        <interface>
            <name>IGnss</name>
            <instance>default</instance>
        </interface>
    </hal>

the rest is already attached above and you should be good to go
ifeq ($(BOARD_HAS_GPS),true)
…

make shure gps.default.so in Folder as shown above and in gps_cfg.inf use

NMEA_PORT_PATH=rild-nmea

you should receive GPS Info via cat /dev/ttyUSB1 as defined above and during rild-nmea in GPS Tracker

For USB Audio Routing/Mixing/UAC in Android i´m in the same situation as you are.
i´m still waiting for Feedback from Quectel since to point only to EVB kit Audio HW without sample under Android is kinda useless.

As requested here EC25 LTE Voice Audio | Android 9.x
At least you should check the USB AUDIO UAC Manual to enable Audio Device as Card(N) under

Device ID´s can be different due multiple Audio Devices depending on your Board.

tcandroid291.apk · July 23, 2020, 2:50pm

Wait GNSS service starts twice
‘vendor.gnss_service’
and
‘gnss_service’
So somewhere you have duplicate entry, besides this what did you changed also due gsm was working before.

Hi,

Thank you for your valuable support.
We did the changes as your instruction for testing GPS in android.

In boot log if we enter below command it will show like,

iwg34m_8mm:/ # getprop | grep gps
[persist.sys.gps.lpp]: [0]
[ro.kernel.android.gps]: [ttyUSB1]
[ro.kernel.android.gps.max_rate]: [1]

[ro.boottime.gnss_service]: [11865840875]
[ro.boottime.vendor.gnss_service]: [12452596500]

Whether same result you observed as above.? if not share your above two command prints?
Can you please share me how you test GPS in android.?
For EC25 quectel module which GPS antenna you are connected(part number)?

We tested with google map and GPS TEST v1.5.4.APK file, but we din’t get the expected behavior.

Hi,

Thank you for your valuable support.
We aslo tested GPS, for us it is working.

Now we are testing voice over USB with AT command.
We are able to call and receive the call with AT command, but it is not audible.

Have you tested voice over a USB with AT command.?
If you are tested, Can you please share the changes.?
