Ligne 71 :
Ligne 71 : − There are multiple parameters that need to be configured correctly for two modules to talk to each other (although with the default settings, all modules should be able to talk to each other). They need to be on the same network, as set by the '''ID''' parameter (see "Configuration" below for more details on the parameters). The modules need to be on the same channel, as set by the '''CH''' parameter. Finally, a module's destination address ('''DH''' and '''DL''' parameters) determine which modules on its network and channel will receive the data it transmits. This can happen in a few ways:+ + + + + + Ligne 79 :

Avec l'utilisation des paramètres par défaut, tous les modules doivent être capables de communiquer ensembles.<br />
Cela signifie que si vous prenez '''deux''' modules identiques, par défaut, ces derniers établiront automatiquement une communication sans fil et seront capables de dialoguer ensemble sans devoir modifier/configurer les paramètres XBee.
Au dela de deux modules ou établissement de plusieurs "réseaux" sans fil, il faudra passer par une étape de configuration.
Il y a plusieurs paramètres qui doivent être configurés correctement pour que deux modules puissent dialoguer ensemble au travers d'un connexion sans fils (although with the default settings, all modules should be able to talk to each other). They need to be on the same network, as set by the '''ID''' parameter (see "Configuration" below for more details on the parameters). The modules need to be on the same channel, as set by the '''CH''' parameter. Finally, a module's destination address ('''DH''' and '''DL''' parameters) determine which modules on its network and channel will receive the data it transmits. This can happen in a few ways:
* If a module's '''DH''' is 0 and its '''DL is less than 0xFFFF''' (i.e. 16 bits), data transmitted by that module will be received by any module whose 16-bit address '''MY''' parameter equals '''DL'''.
* If a module's '''DH''' is 0 and its '''DL is less than 0xFFFF''' (i.e. 16 bits), data transmitted by that module will be received by any module whose 16-bit address '''MY''' parameter equals '''DL'''.
Again, this address matching will only happen between modules on the same network and channel. If two modules are on different networks or channels, they can't communicate regardless of their addresses.

For the "Series 2" modules you must chose which firmware put on the module to give it Coordinator, Router or End Device functionality. Series 2 use only serial low (SL) and serial high (SH) for addressing.
