Macrodroid and traccar app client

Hi

I would like to remotely change frequency parameter in traccar client using macrodroid.

For example a trigger is an sms received in macrodroid which change the conf file of traccar app ...

So question is there a conf file created when you set parameters and launch app ?? if yes maybe i will able to automate changing parameters with macrodroid.

Thanks in advance

Settings are stored in the standard Android preferences. It is a file, as far as I know, but not sure you would be able to access and modify it.
