We have been developing with part number EM7565_1103520, i.e. the non-CBRS-enabled variant, within an embedded Linux product. We have a custom toolchain, and hence we custom compile the QMI SDK using this toolchain.
We are moving to an initial pre-production run and I have noticed that we have been quoted part number EM7565_1104207. A little research shows that this is the CBRS enabled version. We are only using our product within Europe and we don’t need the CBRS facilities.
This leads to a few questions/concerns. I have asked these questions to our authorized distributor, but haven’t received an official answer as yet. I was wondering what the communities opinion/experience was?
Do Sierra Wireless intend to continue to produce both variants? [We don’t want to CE-mark with one part number and then be forced to move to another. Any change of radio component would, as a minimum, involve a paper-work Technical File that would require review by our Notified Body. Hence there would be a cost for this.]
Would using the EM7565_1104207 affect our software interface (SDK) in any way?
Is a different firmware image used with the EM7565_1104207 compared to the EM7565_1103520? [This could lead to a production issue as we don’t want to control production for two different builds.]
