Configuration abp

Hi,
I am trying to configure an end node with ABP, but I have problems with how this data is filled in the device profile, the band I am using is US915 in the first eight channels.

It is very likely that the RX1 data-rate offset is 0. Please refer to the Regional Parameter specification for the meaning of this value, it depends per region.

Hi @brocaar I see that there is a lot of confusion about how to fill several parameters like these, which arises the question of if the default UI values are left, the recommended values are taken in (from the regional parameters)? This is done automatically by the stack? where we can see that parameters and default settings when you are not declared textually on the stack, Or, on the contrary, we should always look for the LoraAlliance documents and fill ALL the UI fields?
