The nRF91 series of modem firmware are distributed with FOTA-TEST diffs to allow for validation of FOTA integrations.
Will the nRF93M1 firmware images be distributed with the same functionality?
I have been testing %HTTPFOTADL from v1.4.1 to v1.5.0 with http://firmware.nrfcloud.com/93m1/mfw_nrf93m1_update_from_1.4.1_to_1.5.0.bin, and found that the modem behavior does not match the documentation. I am unsure whether this is because the AT command behavior changed between 1.4.1 and 1.5.0, or whether the documentation is wrong. A FOTA-TEST diff would help to diagnose the issue.
Specifically, after the '%HTTPURC: "FOTA","DOWNLOADED"' message, there was no '%HTTPURC: "FOTA","VERIFIED"' message that I expected from the docs.....
Instead, the modem started outputting '%FOTA' notifications.
%FOTA: "APPLY"
%FOTA: "UPDATING"
%FOTA: "UPDATING",7
...
%FOTA: "UPDATING",100
%FOTA: "DONE"
RDY
Annoyingly, the "UPDATING" and "DONE" messages are also not documented in the %FOTA documentation.
