Uplink Message
Important Note
For more informations, please refer to the full documentation, check the only endpoint documentation, you can found example and description of all fields.
Message structure
-
All Uplink (UL) and Downlink (DL) messages use JSON format.
-
All datetimes use the ISO8601 format.
Multiple parameters set on the connection configuration can impact the output format (For instance, sendRawDecodedFormat).
See below an uplink example:
Original message
The following Uplink message is sent by all connections from ThingPark X IoT Flow to any IoT cloud platform (regardless of connector type).

| Properties | Description |
|---|---|
Time | Time when the message is send |
DevEUI | Id of the device which send the message |
FPort | Port used by the device |
FCntUp | Uplink frame counter. Used to know if the device lost any frame. |
ADRbit | ADRBit set by the device. ADRbit is not filled in the document, if not set in the uplink frame. Syntax: NUMBER (Unsigned integer: 0..1) |
MType | LoRaWAN® MType of the packet. Syntax: NUMBER (Unsigned integer: 0..7) |
FCntDn | Downlink frame counter. Used to know if the device lost any frame. |
payload_hex | Message in its crypted format. |
mic_hex | MIC in hexadecimal ASCII format. Syntax: STRING (Hexadecimal representation) |
CustomerID | Id of the customer |
CustomerData | JSON customer data set by provisioning:
|
InstantPER | Instant PER (Packet Error Rate). The instant PER is computed from a sliding window of last packets. Syntax: NUMBER (Float) |
MeanPER | Mean PER (Packet Error Rate). Syntax: NUMBER (Float) |
DevAddr | Device DevAddr. Syntax: STRING (Hexadecimal representation) |
AckRequested | ACK requested indicator (Boolean). Syntax: NUMBER (Unsigned integer: 0..1) |
rawMacCommands | Hexadecimal ASCII dump of the LoRaWAN® MAC option or LoRaWAN® MAC payload (port=0). Syntax: STRING (Hexadecimal representation) |
NbTrans | The number of transmissions for each uplink message requested by the LRC, according to ADR algorithm and validated by the device through a LinkADRAns MAC command. If no LinkADRAns have been yet validated by the device, NbTrans = 1. Syntax: NUMBER (Unsigned Integer) |
TxPower | The transmission power of the device (in dBm), computed by the LRC based on ADR algorithm and validated by the device through a LinkADRAns. If no LinkADRAns have been yet validated by the device, the device boot parameter is used instead. Syntax: NUMBER (Float) |
Gateway properties
| Properties | Description |
|---|---|
Lrcid | ID of the LRC that processed the packet. Syntax: STRING (Hexadecimal representation) |
LrrRSSI | Gateway's signal strengh (including disturbance). |
LrrSNR | Gateway's signal to noise ratio. (min: -20, max: 19). The higher the number is, the purest the signal is. |
SpFact | Spreading factor used by the device. It's the transmission speed on air. (min: 7, max: 12). |
SubBand | Sub-band used by the device. Syntax: STRING |
Channel | Channel used by the gateway to send the packet. |
DevLrrCnt | Frame counter of the gateway. (a verifier si c'est en relation avec fcntup) |
Lrrid | Id of the gateway used to send the packet. |
Late | Indicates if the packet was queued by the LRR. Late is always filled.
|
LrrLAT | Latitude of the gateway |
LrrLON | Longitude of the gateway |
Lrrs | List of associated gateways |
