I have made another script listening directly to Location API.

I use it in my car’s head unit for GPS speedometer.

Although GPS speed can be obtained with my other script that takes data from Torque, this one makes it unnecessary to use Torque, and may get data updates just a little bit sooner.

The variables set by script are:

gps_live – boolean – indicates that location API is ready (i.e. enabled and ready)

gps_speed – float – the speed in m/s (must be multiplied by 3.6 to get km/h)

To use, make text with binding like follows:

($gps_speed * 3.6).toFixed(0)

Also, text display can be bound to $gps_live

The script requires a permission which is missing in LLX:

android.permission.ACCESS_FINE_LOCATION

To make it work, either wait for developers to add a permission APK for that, or use this xposed module by Lukas Morawietz (if you are using xposed framework): https://play.google.com/store/apps/details?id=com.faendir.lightning_launcher.permission_manager

I would like to share my script for users of Torque https://play.google.com/store/apps/details?id=org.prowl.torque

This script allows reading any PIDs from Torque service, for latter use in bindings.

Set it to be run on desktop load.

It will set the following variables:

tq_live – boolean – whether we are connected to Torque service

tq_ecu – boolean – whether Torque is connected to Engine ECU

tq_version – integer – the version of Torque

tq_xxx – float – the value of pid, where xxx is a name of pid as configured at the top of script, you may configure multiple PIDs; see below

Hello,

I have an advanced question about scripting.

Is it possible at all to communicate with a 3rd party remote service from a script? You know, Context.bindService() and all those things. Provided I have that service’s AIDL file.

I understand that AIDL is for generation of stub and proxy for “real” Java code. But maybe it can be done from JavaScript using bare Binder/Parcel classes?

I’m not as experienced developer to figure it out myself, sadly 🙁

What’s on my mind – is to communicate to famous Torque application, which provides API for plugins:

https://torque-bhp.com/forums/?wpforumaction=viewtopic&t=438.0

https://torque-bhp.com/ITorqueService.aidl

What I would like to call on this service is:

float getValueForPid(long pid, boolean triggersDataRefresh);

Thanks in advance for any clue 🙂
