Is it possible to do Remote (over the air) re-configuration to Universal Tracker software on SARA SFF trough NB-Iot network ?
Yes, you can change a few settings over the air.
You can find the payload format in the Remote (over the air) re-configuration section in the GitHub readme.
Thanks. How could I format this messages with the All Things Talk interface ?
I don’t think this is possible with AllThingsTalk at the moment.
You can contact AllThingsTalk’s support team to see if or when sending back is available.
