Interpreting a 4G LTE module output, $QCNETDEVCTL: 0/1
-
I have been having problems diagnosing why a SIM7670G 4G LTE module board keeps loosing service and failing after a couple hours.
It is displaying these codes:
$QCNETDEVCTL: 0
$QCNETDEVCTL: 1My searches get no results, SimCom tech support is not responding.

Hi,
SIMCOM SIM7670G LTE cat1bis - Qualcomm QCX216 chipset$QCNETDEVCTL is a Qualcomm command
Taking at-cmd manual from e.g. cavli C16QS module (same chipset) - see below.
These URCs display the state:
0 Bind cid for LWIP failure
1 Bind cid for LWIP successCheck the setting: AT$QCNETDEVCTL?
This will not solve your connectivity issue…but explains the URC.

AT$QCNETDEVCTL
Description
The command set data path control for the network adapter. Control data path open by setting <op> to bind LWIP to PDN context with <cid> . Control data path close by setting <op> to unbid LWIP to PDN context with <cid>.
SyntaxAT$QCNETDEVCTL=<op>,<cid>,{,<urc_en>}
AT$QCNETDEVCTL?
AT$QCNETDEVCTL=?
–> $QCNETDEVCTL : (list of supported (<op>,<cid,<urc_en>)s)<op>
Specifies device control option
0 Unbind cid for LWIP
1 Bind cid for LWIP once and no rebind if re-activate PDN context with same cid after deactivation
2 Bind cid for LWIP and rebind if re-activate PDN context with the same cid after deactivation
3 Auto dial and bind cid when power on, saved in NVM after power down<cid>
Specifies a Particular non secondary PDP context definition. <cid> values of 1-15 are supported.<urc_en>

0 Bind cid for LWIP failure
1 Bind cid for LWIP successNote:
If the <cid> for PDN context defined but deactivated , bind this <cid> will auto activate PDN context. If the <cid> for PDN context undefined, bind this <cid> will cause activation failed.
