+SCAST – Transmit Data To The Sink
Execute Command
AT+SCAST:
Example
AT+SCAST:Hello world
Use on
All Devices
Response
SEQ:XX
OK
or ERROR
Where represents the error code
explained in section 3.
Notes
- When bit 8 of S10 is set, if a sink
cannot be reached for three
consecutive transmissions the sink is
assumed unavailable and a new one
is sought
- The ACK and/or NACK prompt can
be disabled in S0E
- When attaching the node‟s EUI64 to
the network frame the maximum
payload reduces to 74 bytes
- The maximum payload is 82 bytes. It
is reduced by 8 bytes when
appending the EUI to the network
header (default) and also it is reduced
by 2 bytes per hop in case a source
route is known. The latter event can
neither be suppressed nor foreseen.
Prompt
ACK:XX
or NACK:XX
Parameters
Up to 82 bytes are sent to the node‟s sink. On
successful transmission the user is given the
sequence number followed by “OK”. After that the
user is prompted “ACK” on receipt of an
acknowledgement or “NACK” in case the message
was not acknowledged. A NACK does not
guarantee that the message has not reached its
destination.
Remote action
Prompt
UCAST:[,]=
Where is the address of the sender and
is the length of the message in
hexadecimal. The EUI64 is only displayed if it is
part of the network header (set bit 0 of S10 to
disable attaching the EUI64 to outgoing
messages).
