Info about installed Software version

[ismarslomic]

Thanks for very nice lib for retrieving data from my I-Pace!

Just wondering if there are any data available about currently installed software version(s)?

Hey!

The API does expose a few software version numbers, primarily related to the TCU. Look at the TU_STATUS_SW_VERSION_MAIN status value for example. It correlates to a TCU software version. I've created a mapping between known values and the readable equivalents (14.2, 16.2, etc) and implemented them in WattCat. However, from my experience it doesnt seem like all cars actually provide updated version info through the API. My car still returns the equivalent of 14.2 even though I'm on 18.2.

Right, I have seen the version data for TU_STATUS_SW_VERSION_MAIN (which is the only software version field), which for my car is L8B2-70712-AX. How does this map to the readable equivalents you are referring to (what is the mapping logic)?

I havent seen that value before I'm afraid. Its also region specific so I only have the most common ones nailed down tbh.

 @Nullable
     public static String getAlternateTcuVersion(String tcuVersion) {
         switch (tcuVersion) {
             case "J8A2-70712-AS":
                 return "14.2";
             case "J8A2-70712-AT":
             case "J9C3-70712-AT":
                 return "15.2";
             case "J8A2-70712-AV":
             case "J9C3-70712-AV":
                 return "16.2";
             case "J8A2-70712-AX":
                 return "17.2";
             case "J8A2-70712-AY":
             case "J9C3-70712-AY":
                 return "18.2";
             case "J8A2-70712-AZ":
                 return "19.2";
             default:
                 return null;
         }
}

Anywhere I can find these translations documented?

[ardevd]

What do you mean exactly?

[ismarslomic]

How did you find out that for instance J8A2-70712-AS maps to 14.2? Where these mapping rules documented somewhere?

[ardevd]

The mapping rules are the result of surveys I did on various owner forums, so it's not based on any official documentation (there is no such thing) but rather community reported data.

I'll close this for now. Feel free to open a new one if you have more questions.

Cheers
