Battery and assistance Level in FIT file

I'm using the FIT SDK to encode the data in the .fit file.

I would to record battery level and assistance level in order to import these data in Gamin Connect.

I'm using these 3 functions

setEbikeBatteryLevel

setEbikeAssistLevelPercent

setEbikeAssistMode

but nothing of these information appears on Garmin Connect.

The SDK generate these tag (visible using FITtoCSV tool)

ebike_battery_level
ebike_assist_level_percent
ebike_assist_mode

I asked to my friend to send to me the .FIT file where he can see the battery and the assist mode as you can see in this screen shot

The FIT file contains the tags

currBattery
currAssist

I tried to add these tag with DeveloperField class, but I'm not able to see the graph of the Battery and assistance level.

What can I do?

Thanks in advance for your help.

If you have the file from your friend, start removing individual fields from it, and watch for the moment it stops displaying the additional data. In the moment it happens, you found the culprit (although there may be several of them).

Once you trim it down to the necessary minimum, mimick the remaining stucture in your script.

Which tool I can use to remove the fields?

If you work with the CSV files generated by the FITtoCSV, then with Notepad, Excel or similar.

Ok, I know how to remove the field in notepad.. but then I need to regenerate the FIT file.. Is there also the CSVtoFIT? Garmin Connect doesn't accept the CSV created by FITtoCSV..

You can convert the files from CSV to FIT with the same tool. Call it with the option -h to get the syntax (or read the documentation). You will probably get an error complaining about undefined fields too - you either need to redefine them, or remove them too. Google the error message - there are some solutions online.

You can also use the [FIT File Repair Tool] for manipulating the FIT files directly, though I am not really well familiar with it, so cannot tell you whether you can use for exactly this purpose.

You are right.. sorry.. this is my big fault.. I will try to use the FITtoCSV with the correct option.. I will let you now which is the correct parameter.. Thanks again for your support..

What I understood until now is that the message with ID 104 is not implemented in the SDK.

The tool [FIT File Repair Tool] (very useful) highlight the Battery TAB when there is a Message Type ID 104

But this message is not developed by the SDK.

Infact the FITtoCSV export a lot of "unkwon" field due to this missing implementation.

Someone knows if this will be implement in the next releases?

I do not think you will find anyone knowing it here. Try posting on the developer forum - perhaps there is someone from Garmin commenting (though I have doubts about it).
