Hello,
Hello Robert,
The question popped up at our end because we were looking at the plots of measurement results generated by different probes. We wanted to make sure these probes were comprised of the same hardware and that they run the same firmware version. It’s great that each UDM attaches the firmware version of the probe as a tag in its results. However:
a) Although, the hardwares currently are capable of running the same firmware revision, but as you mentioned, at times they diverge away.
b) Would different hardwares always support the latest firmware version? I ask because v3 is more capable than v1/v2, and I don’t know if you plan to diverge away the firmware at some point to provide more measurement capabilities for v3 probes.
As a general rule, we keep the firmware versions in sync across hardware revisions in order to have the same capabilities available. The current situation is a bit of an exception, but that's only because we needed to deploy a new firmware for one hardware version only; functionally there's no difference.
Due to a) and b) would it make sense to also attach the hardware version (v1, v2, v3) of the probe as a tag in each UDM result as well? We don’t know if different hardwares have effects on the measurement results. We can cross-confirm this if the UDMs attach a hardware version in addition to the firmware revision.
This would be possible, though (with some more documentation from our end [*]) one could also easily determine the hardware version from the probe ID. Regards, Robert [*] the quick version: - ID < 1500: v1 - 2000 < ID < 5000: v2 - 6000 < ID < 7000: anchor - ID > 10000: v3
Thanks!
Best, Vaibhav
