I'm using NXP Test Tool to Over-The-Air update the firmware of multiple target platforms (based on KW41z).
Updating a single module takes arround 5 minutes. But if a update 10 module at once, OTA time will increase to approx. 30 minutes!
In NXP Test Tool Software, there is a (greyed out!) checkbox for enabling OTA Multicast, which I can't set to active.
What can I do to enable OTA Multicast?
Are there some other performace optimizations I can do, to speed up OTA process?
regarding the multicast feature in the NXP Test Tool it is not free feature as Estephania mentioned you need to contact local sales team.
To make the process faster you will either need to use multicast or update a smaller image.
For more information on how to enable the multicast in the NXP Test Tool, please contact your local sales team.
If you have any other doubt, please let me know.
