Testing in build 743( with latest firmware 2.4.8),it treat Reader 2.4.7 as 'Incompatible sensor' expect it should treat Reader 2.4.7 as 'up-to-date', what I heard that RSU should treat both 2.4.7 and 2.4.8 as up-to-date..
this scenario is part of SIT execution.
I believe 2.4.7 will never be found outside a test environment. So we should consider it an invalid version if we find it.
Olson, Jennifer reply a mail and said how to treat 2.4.7 Reader. " It will be installed on FSL Algo readers as manufactured starting in Jan 2019. It will definitely be in the field, and yes should be treated as up to date "
Sujit confirmed that 2.4.7 would not be used anymore. t This is a invalid test cases now since 2.4.8 is the only firmware available for those country deployed with RSU utility. Resolve invalid.
