WP7608 Android RIL Integrate Issues(QMI interface.)

IoT Modules WP Series
1

we try to install the RIL for the WP7608 in our Android 7.1 (AndroidRIL_V7.1.6_ARM64_7.1_V1.0_bin).

We have installed the kernel files and the RIL Driver so far. We have integrate the Android modifications also.

After Integration The device is able to emulate as a USB interface and I am able to run the AT commands over UART(minicom interface) and device is responding. But I am facing issues with Android rild.

ttyUSB0
ttyUSB1
ttyUSB2
qcqmi0

For RIL integration I followed steps mentioned in below document
(AirPrime - Android RIL Integration Guide - 4117325 - Rev1.4)

Please help us resolving this critical issue and for your reference please catch the logs as below.

In logcat -b radio we see:

Now I’ll at least be able to get one step further in the Getting Started.

I appreciate your thoughtful reply and help

Thanks & Regards,

Hi Venkatesh,
Thanks for info.
Seems like similar issue as MC7430 Android QMI not connecting

Per log, ttyUSB0 is owned by bluetooth/bluetooth, so RIL may not able to access and consider device not available.
Would you fix and set ttyUSB0 to radio/radio (same as ttyUSB1/2 and qcqmi0) and see any improvement?

Thx

5

Please find the below info

Yes I changed to ttyUSB and qcqmi device properties as radio, please find the below info

130|msm8953_64:/ # ls -l /dev/ttyUSB*
crw-rw---- 1 radio radio 188, 0 2018-09-17 17:46 /dev/ttyUSB0
crw-rw---- 1 radio radio 188, 1 2018-09-17 17:46 /dev/ttyUSB1
crw-rw---- 1 radio radio 188, 2 2018-09-17 17:56 /dev/ttyUSB2

msm8953_64:/ # ls -l /dev/qcqmi0
crw-rw---- 1 radio radio 228, 0 2018-09-17 17:46 /dev/qcqmi0

Still device is not UP, but device is able to detected. For you reference, Please catch the attached logs.

From log, Sierra RIL is communicating with WP7.
However, it looks like another RIL “QtiRilInterface” is reporting radio not available:

09-17 18:01:40.872 I/QtiRilInterface( 1569): getUiccIccId iccId[0] = null exception: com.android.internal.telephony.CommandException: RADIO_NOT_AVAILABLE

Any reason why you have 2 RIL running? Please try disable and keep only Sierra RIL run and see any improvement.
Thx

Dear lotam,

We have connected only one WP7608 device to other end. seems, It could be the RIL deamon issues,

QtiRilInterface is external telephonic features it may not effect this Sierra modem, We have integrated other modems also there i can see same logs and modem integrated successfully.

Can you please check the why RIL deamon disconnect every time, I am suspecting that due to this RIL device is crashing .
09-18 20:08:07.181 1574 1675 I RILJ : (0) Disconnected from ‘rild’ socket.

If you possible can you share the source code of RIL or recheck the RIL Issue.

Please catch the attached logs .

Try to resolve the issue as soon as possible and I appreciate your thoughtful reply and help.

There are lots of log mention “QTI”, would you please check init.rc of your system what ril is enabled?
Also,

ps | grep ril
getprop | grep ril

Thanks

Hi lotam,

Thanks for reply.
There is another RIL running, “com.qualcomm.qcrilmsgtunnel” and probably the Android telephony framework was modified for this qcril, these may cause conflict with the Sierra RIL.

Again, I would suggest to make sure only 1 Sierra RIL running with standard telephony framework.

11

Hi Venkatesh.

I am having an issue before that.

Could you please list the commands you used to compile and install the kernel files and the RIL Driver?

Thanks!

Hi,

I am having the same problem with same behavior.

Is there a solution ?
