New parsed field #51

Closed fabsi closed 3 years ago

fabsi commented 3 years ago

Hello,

I am working on an device which use lora.

I tried to parse the following frame : Message Type = Data PHYPayload = 6049270226BA00000340020071033500FF0101867B63F7834E04CAC51E59

      ( PHYPayload = MHDR[1] | MACPayload[..] | MIC[4] )
              MHDR = 60
        MACPayload = 49270226BA00000340020071033500FF0101867B63F7834E04
               MIC = CAC51E59

      ( MACPayload = FHDR | FPort | FRMPayload )
              FHDR = 49270226BA00000340020071033500FF01
             FPort = 01
        FRMPayload = 867B63F7834E04

            ( FHDR = DevAddr[4] | FCtrl[1] | FCnt[2] | FOpts[0..15] )
           DevAddr = 26022749 (Big Endian)
             FCtrl = BA
              FCnt = 0000 (Big Endian)
             FOpts = 0340020071033500FF01

      Message Type = Unconfirmed Data Down
         Direction = down
              FCnt = 0
         FCtrl.ACK = true
         FCtrl.ADR = true

It seems that the field FPending in FCtrl is missing.

Could you help on that?

Regards,

it looks like FPending is being decoded (e.g. see getFCtrlFPending in the source) but it's missing from the documentation & the text output

I'll fix this
