<val> Unit is in minute. Default value is 0 (connection control disabled). Valid range is 0 to 65535.
4 UDP only prefix data bytes. After Auto UDP is connected, the data will be outputed to the server.
<val> set of hexadecimal bytes entered between quote; example: "010203", will send 0x01, 0x02,
0x03.
5 heartbeat period. After Auto TCP/UDP is connected, an heartbeat packet "HELLO" (5 bytes) will be sent
to remote socket on the period defined by <val>. The modem will expect a reply packet from remote
that contain a hex 0x00 payload data (1 byte). If the modem cannot get the reply packet after sending 3
consecutive heartbeat packet, the modem will reset and reconnect.
<val> Unit is in second. Default value is 0 (connection control disabled). Valid range is 0 to 180.
6 serial prefix data. Whenever there is data received from remote TCP/UDP peer, the modem will first
send out a "Prefix ID" by default 0x01 (1byte) from modem’s serial port to the connected device, followed
by received data. You can customize the prefix by adding a second parameter <prefix>.
<val> is 1 to activate it, 0 to disable (default).
<prefix> is optional by default it is 0x01. Prefix ID has to be entered as a hexadecimal number.
Range from 0x00 to 0xFF (1 byte only).
Example:
Command Response
AT+AUOPT=1,5 OK
Note: set the socket idle period to value to 5 (min).
AT+AUOPT=2,720 OK
Note: set the server idle period to value to 720 (min).
AT+AUOPT=3,15 OK
Note: set the socket connect period to value to 5 (min).
AT+AUOPT=5,180 OK
Note: activate heartbeat of 180s.
AT+AUOPT=6,1,06 OK
Note: activate and set prefix ID to 0x06 value.
AT+AUOPT=1,0 OK
Note: set the socket idle period to value to 0 (disable).
AT+AUOPT? +AUOPT: 1,0
+AUOPT: 2,15
+AUOPT: 3,750
+AUOPT: 4,""
+AUOPT: 5,0
+AUOPT: 6,0
OK
AT+AUOPT=? +AUOPT: (1-6),(0-65535),(64),(0-180),(0-1)
Note:
– When <option> #1 is enabled with client mode, the serial port of the modem will be changed into data mode
without waiting socket connection. And once data enter to serial port data will be buffered and then start
connecting remote TCP server. This option is good when remote TCP server is not good for keeping socket all
the time.
– If options are modified while connection is active, new entered values will apply only after a disconnection
and new connection is established. Options #1, #2 & #3, currently require AutoTCP/UDP to be disabled then
re-enabled.
– When socket for TCP Terminal is connected, cellular deactivation, by <option> #2 timeout, will be deferred.
