I have the same issue, @luca-ferrari-roma have you solved? |

@markusvankempen I copied your new flow but I can't, there are some errors ... In your original flow I use my own payload and my appkey and nwkey and I obtain the error that @luca-ferrari-roma have posted. On the website the same datas that I used on Node-RED work perfectly. |

@markusvankempen what do you mean with .org.? This is my version, I put my payload on data field (inject node) and my nwkey,appkey on Decrypt node. Payload: 404A23C1AB0085010174F2F25959595D2BAC0E5D7F8B4DCFF7463930682D The decrypted message is: T:25:U:1566:X:111 On the bottom there's the flow, if you want to test it, the error is: |

Thank you @markusvankempen for your replies, I solved my problem! |
Hi again Markus.
I have created this simple decrypting node, but, a cannot more be able to decrypt any simple payload message.
The output message is:
Network Key issue! Raw packet: Message Type = Data
PHYPayload = 4010190126006B0003DCB3C9BA1C8B494D0207EB837C2128F565E988
( PHYPayload = MHDR[1] | MACPayload[..] | MIC[4] )
MHDR = 40
MACPayload = 10190126006B0003DCB3C9BA1C8B494D0207EB837C2128
MIC = F565E988
( MACPayload = FHDR | FPort | FRMPayload )
FHDR = 10190126006B00
FPort = 03
FRMPayload = DCB3C9BA1C8B494D0207EB837C2128
( FHDR = DevAddr[4] | FCtrl[1] | FCnt[2] | FOpts[0..15] )
DevAddr = 26011910 (Big Endian)
FCtrl = 00
FCnt = 006B (Big Endian)
FOpts =
Message Type = Unconfirmed Data Up
Direction = up
FCnt = 107
FCtrl.ACK = false
FCtrl.ADR = false
FCtrl.ADRACKReq = false
Some ideas?
Thank you
Luca
