Unsolicited Result Code Presentation
URC stands for Unsolicited Result Code and is a report message issued by the ME without being requested by
the TE, i.e. a URC is issued automatically when a certain event occurs. Hence, a URC is not issued as part of
the response related to an executed AT command.
Typical events leading to URCs are incoming calls ("RING"), waiting calls, received short messages, changes in
temperature, network registration etc.
For most of these messages, the ME needs to be configured whether or not to send a URC. Descriptions of these
URCs are provided with the associated AT command. URCs which are not user definable are described in Sec-
. A summary of all URCs can be found in Section
Important:
If the interface used for URC output is reserved by an active data connection or a long running AT
command, URCs are buffered internally and will be issued after the interface becomes idle again. A pending
URC will be signaled on the URC output interface via RING line. This allows to systematically suspend any longer
data connection (refer
) to check for pending URCs after being signaled!
For detailed information regarding configuration of URC signaling refer to
, "URC/Ringline",
Parameter Description
200
URC will be send 40 seconds after powerup when the JRC midlet was not tried
to start (no autostart, no midlet at all, whatever). Used to see in logs, that midlet
is not running, as example.
201
The JRC midlet was started, but did not succeed to full init itself within a (JRC
midlet defined) timeout. 5 seconds after this URC, the ME will restart.
202
The midlet was tried to start 5x, but was restarted (with ^SYSINFO: 201). Now,
the JRC midlet start was cancelled. No JRC midlet is running. A shutdown
timer of 10 minutes is started. After this timer, the ME will be switched off.
1.8.1
Common URCs
This section describes all URCs not associated to a certain AT command. They cannot be defined by the user
and appear automatically when the conditions described below occur.
Notes for "^SBC" URCs reporting undervoltage/overvoltage conditions:
for specifications regarding the minimum and maximum operating voltage limits. If the supply
voltage exceeds the defined thresholds the ME switches off automatically. The automatic shutdown procedure
is equivalent to the power-down initiated with the
command.
URC 1
^SYSLOADING
Indicates that the ME is in the process of starting up. Do not enter AT commands until the "
" URC
has shown up.
URC 2
^SYSSTART
Indicates that the ME has been restarted to Normal mode or Airplane mode and is ready to operate.
For Normal and Airplane mode see
Note: Autobaud mode (see
) requires an "AT" or "at" string be given after restarting the ME. This
enables the ME to detect the bit rate set in the TE. After detecting the bit rate the ME will send the "
" URC.
