Ligne 346 :
Ligne 346 : − Locate the following lines:+ + + + + − − − The NODE_ID and BASESTATION_ID are preconfigured and doesn't need to be updated (they can be updated for test purpose). − − {{underline|Note:}} the frequency & encryption key are enough to "isolate groups". Nodes ID are used to create mesh network within a group. A simple mesh with 2 nodes: the Receiver base station and the Emitter CanSat. −
→Emitter code
* The '''BaseStation ID''' the node id (0..255) where the CanSat emitter must sent the messages (and from which the ACK response are expected).
* The '''BaseStation ID''' the node id (0..255) where the CanSat emitter must sent the messages (and from which the ACK response are expected).
The NODE_ID and BASESTATION_ID are preconfigured and doesn't need to be updated.
{{underline|Remark:}} the frequency & encryption key are enough to "isolate a group". Nodes ID are used to create mesh network within a group. A simple mesh with 2 nodes (the Receiver base station and the Emitter CanSat) is enough to exchange messages with Acknowledgement.
Anyway Node ID can be updated for test purpose. To do so, locate the following lines:
<syntaxhighlight lang="python">NODE_ID = 120 # ID of this node
<syntaxhighlight lang="python">NODE_ID = 120 # ID of this node
BASESTATION_ID = 100 # ID of the node (base station) to be contacted
BASESTATION_ID = 100 # ID of the node (base station) to be contacted
</syntaxhighlight>
</syntaxhighlight>
