Important Reminders

["UHF OpenEdition 400-480MHz" and "VHF OpenEdition 134-174MHz"
These two versions cannot be used directly for programming.
OpenEdtion used SA868 open-edition module, which internal Micro-controller is erased and left blank after the Factory QA test.
There is no published open-source firmware, so you cannot test the RF functionality directly on them, you need to develop it yourself or follow the progress of the open-source community.]
