Which fields I need to modify in file .fit (.csv) to change device and to add in garmin connect in activities and challenge

Data,0,file_id,serial_number,"3420897194",,time_created,"1062594924",,unknown,"4294967295",,manufacturer,"1",,garmin_product,"3992",,number,"65535",,type,"4",

For changing the device you can change this following part:

- manufacturer,"1". means Garmin

- garmin_product,"3992". means fr255 (forerunner 255).

    If the FIT file is created by other manufacturer, the name will be just product not garmin_product


You can get the list of manufacturer and garmin_product list in Profile.xlsx. However for non-garmin product list, I don't know if Garmin or thisisant publishes the list, or maybe it's up to manufacturers to publish, if they do publish the list, I would like to get updated as well. I hope Ben FIT is willing to answer this (?)
