Text Mode
PDU Mode
When entering the telephone number in the
Recipient
field, enter the full international
number starting with
+
.
Note:
If
+
is omitted in the
Recipient
field, the message will be sent from the
BRM, but the destination may not be
resolvable by the SMSC which would
result in the message not being delivered
to the other end.
The telephone number and the type is encoded in the
pdu message itself. Although some encoders
constructs the PDU without considering the
+
in the
recipient number, please ensure that a
+
is not used
with the recipient number.
Note:
If PDU is constructed with
+
,
AT+CMGS
command immediately returns
ERROR
.
When composing a message using the
Text
mode, please remember that the size
limit for a message is 140 bytes (equivalent
to 160 characters with the GSM 7-bit
encoding used for Text mode).
If more than 140 bytes need to be sent, they can be
sent as concatenated PDU strings in PDU mode. Each
PDU string is sent separately which are received at
the remote device where the SMS application would
combine to form on human-readable message.
Note:
The WebUI does not have the intelligence to split a large message to PDU strings nor
combine received PDU strings into a human-readable single message.
10.6.1: Synchronous and Asynchronous SMS Sending Process
10.6.1.1: Synchronous
Synchronous mode ensures that the message is successfully sent. In order to enable this mode, the
Legacy
box has to be checked (unchecked by default).
If the message is sent out successfully, the following response will be given after selecting
Send
Text Message
or
Send PDU Message
:
Success: null
Or, if there is an error in sending:
Error
In this case, the REST command issued, as shown in the
Notifications
page, is:
{“data”:
{”path”:”message”,”username”:”admin”,”method”:”POST”},”type”:”restcm
d”}
10.6.1.2: Asynchronous
Asynchronous mode returns a response immediately with a
request_id
thus immediately freeing
up the REST channel. In order to enable this mode, the
Legacy
box must be unchecked (default
setting).
Whenever the message is sent to the network, a response that includes the unique REST API request
ID will be returned:
Success: {“status”:”sending”,”request_id”:1537803266}
In this case, the REST commands issued, as shown in the
Notifications
page, is:
