ProBee-ZS10 User Guide Rev.1.5
broadcast one packet over 2 seconds for safe transmission. Broadcast transmission failure also causes
retransmission which is affected by transmission timeout(S33) and transmission retries(S32). Because
frequent retransmissions may cause to break the broadcast limitation, it is recommended to set more than
1000 for transmission timeout(S33) and set as small as possible for transmission retries(S32).
Multicast data transmission is implemented on top of the network broadcast mechanism, so it is subject to
the same rules.

Broadcast Data Mode
Broadcast data mode can be used for continuous data transmission to all devices in the current network.
The destination address or group ID of the remote nodes is not necessary for broadcast data mode. The
transmission range is determined by the S-register 35.
