We have an issue with the MC7304 where the communication blocks when an additional call comes in and a call is already in progress (and in some other rare cases). The goal is to see if upgrading the firmware would resolve the issue.
Currently we use
Manufacturer: Sierra Wireless, Incorporated
Revision: SWI9X15C_06.03.32.02 r26426 CNSHZ-AR-BUILD 2015/01/16 01:32:41
IMEI SV: 40
I found a newer version
but I think we need a 06.xx.xx.xx variant, correct?
Is there a new version we can upgrade to? And what are the changes done (release notes would be good)?
Note: I know that the MC7304 is EOL but we have quite a number of them in the field (and on stock) that can’t be easily replaced.
