4. Il modulo può supportare la comunicazione di trasmissione trasparente -a-, -a-molti tramite l'impostazione 'ID La modifica della velocità di trasmissione di una porta seriale cambierà in modo sincrono la velocità con cui i dati vengono inviati via etere. (10kbps-100kbps)
2. Intervallo di frequenza operativa (433 - 458,5 MHz, fino a 255 canali di comunicazione). Potenza di trasmissione massima di 100 mW (20 dBm) (è possibile impostare 10 livelli di potenza). 3. MCU integrato, utilizzare la porta seriale per comunicare con dispositivi esterni. Invia 31 alla volta.
5. Impostare i ''tre minuti critici''. modulo può inviare e ricevere dati normalmente entro tre minuti dall'accensione. È possibile inviare AT '' AT+ENABLE=1 '' per far entrare modulo nello stato AT per l'impostazione parametri. C'è solo questa parola riservata in questi tre minuti. Dopo più tre minuti, non sarai in entrare modalità AT, puoi solo inviare e ricevere dati, ''AT+ENABLE=1'' verrà inviato anche come dati, non ci sono parole riservate in questo momento.
