EC20 firmware upgrade

Hello,
We have EC20 module with firmware EC20CEFDLGR06A04M1G.
We want to know if there is any new firmware available for this module, and how to upgrade it over the air?
Thanks!

HI
Where did you get your module? Please get the differential package from the acquisition module

Hi,
What are all the advantages /error could be debugged if we update the latest EC20 module with firmware EC20CEFDLGR06A04M1G.
Anyone share me the used case or ECN history.
Best Regards,
Ramesh
