====== Data transmission ======

Data can be sent to end-devices. It can be achieved using the web interface from the //Send data// menu.

{{:images:senddataselection_v1.0.png?600|Data can be sent manually or through a csv file}}

The web interface only displays the last message sent. The web interface displays all the queued messages. \\

__List of available status:__
  * Pending
  * Queued
  * Sent
  * Failed
  * Succeed
  * Try 1, 2, 3, 4, 5 

{{:images:senddata_v1.0.png?800|TX data are displayed}}

==== Drag and drop a CSV file ====

=== File Format ===

<file csv TX_Data_Template_v1.1.1.csv>
endpoint_id,port,acknowledge,try_number,payload
</file>

  * ''endpoint_id'': Device EUI or Device Address (depends on activation procedure).
  * ''port'': Port used (in LoRaWAN protocol).
  * ''acknowledge'': true or false.
  * ''try_number'': Number of retry before abort.
  * ''payload'': Payload in base 64 format.

=== Example ===

<file csv TX_Data_Example_v1.1.1.csv>
18B20000000BAA,2,true,3,dGVzdA==
18B20000000BAA,5,false,3,dGVzdA==
18B20000000BAA,2,false,2,dGVzdA==
</file>

===== class A communication =====

"Following each uplink transmission the end-device opens two short receive windows. The receive window start times are defined using the end of the transmission as a reference."

"If the network intends to transmit a downlink to an end-device, it will always initiate the transmission precisely at the beginning of one of those two receive windows."

===== class C communication =====

"Class C devices implement the same two receive windows as Class A devices, but they do not close RX2 window until they need to send again. Therefore they may receive a downlink in the RX2 window at nearly any time, including downlinks sent for the purpose of MAC command or ACK transmission. A short listening window on RX2 frequency and data rate is also opened between the end of the transmission and the beginning of the RX1 receive window."
