<p>Please choose the Sensors that you have enabled in the Firmware. The Payload Decoder code below will change accordingly.</p>
|
||||||
|
<p>Notes:</p>
|
||||||
|
<ul>
|
||||||
|
<li>You can set arbitary combinations of Sensors here. Not all of them are useable / technically possible</li>
|
||||||
|
<li>Enable only the sensors in the decoder, which are enabled in the firmware for a particular device. The Decoder does not detect which sensors are present in the LoRa paket. You can set a payload decoder per device in TTN v3 to have nodes with different sensors in one application</li>
|
||||||
|
<li>The Payload Decoder shown here is for TTN v3 / The Things Stack v3. If you use other LoRa Stacks you may have to change the <b>decodeUplink</b> function and its return value.</li>
