upgrade integration JT701 to JT701D

hi,
we recently purchased the JT701D from Jointech. everything seemed to work fine until we realized that there is a difference between JT701 and JT701D. in fact, there are two versions of this tag. indeed, the supplier asked us to integrate the new version in traccar. it seems that the response codes are different. how to update this tag in traccar?
thanks

If you want to update it yourself, source code is open. If you need help, contact support.
