Help with RADIO

[Simon9050]

Hi,

I have some trouble understanding how interfaces are wired between fsw and cosmos and I would like to ask you a few questions :

• RADIO : My understanding of RADIO interface is that "_radio" targets (for command or telemetry) flows through the radio component.
  However, the cosmos counters (telemetry) stay at zero in my simulation for RADIO interface... Is it a normal behaviour ?
  Why are there 2 separate interfaces with the same targets (RADIO/DEBUG) ? Would it be possible to have a single interface ?
  What is the scope of all the ports associated to RADIO ?
  Could you confirm (or not) that SIM_42_TRUTH interface is there only to plot on cosmos some parameters coming from 42 ?

• it is not fully clear to me what is the format of the packets that are exchanged... I suppose it is only SPP (of the CCSDS stack) as COSMOS seems to manage only this type of packets, however I saw some functions in the code working with Transfer Frames...
  Is the Transfer Frame layer also available for TC/TM ? (If yes, how it can be activated ?)

a question to rule them all... could you suggest some steps to create one single working interface (and maybe adding the TF layer) ?

Thank you for your help
Kind Regards,

Simon
