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 🙂
