MC7455 Android GNSS

IoT Modules MC/EM Series
1

Hi everyone,

I’m working with the AirPrime MC7455 to implement LTE data and GNSS positioning. I’ve followed the Android RIL Integration Guide and my LTE is now working.

For what concerns GNSS, I’ve modified the manifest.xml of the device in order to include also GNSS. Should I include /hardware/qcom/gps or /hardware/interfaces/gnss?

It should use a Qualcomm chipset, shouldn’t it?

In the future I’m planning to downgrade to the WP7607, since I don’t use a lot of features of the MC7455, I think I should change the .rc file to run ril-daemon-at instead of the qmi one for LTE. But for GNSS, what should I do?

Thank you

@ricky.i which Android version you were working with?
Yes, WP76 was support QMI, so you could continue to use QMI RIL.

For GPS, as integration guide mentioned. with MC7455, you just need
“AndroidFS/system/vendor/lib64/hw/gps.default.so should be copied to /system/lib/hw on the target device file system and renamed appropriately for the target device.”

Thanks

Thanks

@wzhang thank you for your reply. I’m working with Android 9 Pie. I’ve managed to get GNSS work by putting the library gps.default.so into /system/lib64/hw, since I’m using a ARMv8 64 bit processor.

Good to know for WP7607, I’ll try to switch devices in the near future.

Hello,

sorry for reopening this old topic, but I’m facing again a similar issue.

I’m updating the kernel on my Android Pie (from 4.14.78 to 4.14.98), due to some bug fixes needed. I backported all modifications added for the MC7455, but I’m having some issues.

At first neither LTE nor GPS were working, I had to force the discovery of ttyUSBx adding

write /sys/bus/usb-serial/drivers/sierra/new_id “1199 9071”

to the init.rc file.

With this I’m now able to use LTE connection, but I still cannot get the GNSS to work. I’ve ported the file gps.deafult.so file and renamed it, but it still doesn’t work. What am I missing?

I’m using the Sierra Ril V9.0.4.0_ARM_64 QMI.

I’d like to add logcat content related to GPS, from boot to me firing an app for GPS info. Hope it helps.
