Quectel Modules with Super SIM

Cellular modems covered on this page

Firmware updates

Firmware updates for Quectel cellular modules are typically available through Quectel support. Please reach out to your Quectel representative or Quectel Support for assistance with firmware updates.

General getting started information

Please refer to the main Knowlegdebase page for modem-independent configuration tips.

Super SIM does not support NB-IoT.

Initialization

Only configure the modem’s Radio Access Technology (RAT) preferences for Cat- M1 only when connecting LTE. Super SIM is compatible with almost all cellular network technologies — the exception is NB-IoT, which is not supported. It is therefore important to ensure that the Quectel-specific command iotopmode is configured to its default setting of 0 — the first numeric parameter of the command below — which sets the module to use Cat-M1 only:

AT+QCFG="iotopmode",0,1

If iotopmode is set to 1 (NB-IoT), the modem will not be able to connect to Cat-M1.

This settings can also be applied to the Quectel BG95.

If you wish to limit comms to LTE only, i.e., do disable 2G (GSM), issue AT+QCFG="nwscanmode",3,1.

That first numeric parameter value of 3 is what indicates LTE only; a value of 1 sets the modem to GSM only. The default, 0, tells the modem to select the RAT automatically.

Configure the URC UART

To configure the Unsolicited Result Code (URC) serial (UART) delivery channel to uart1, issue AT+QURCCFG="urcport","uart1".

Perform a ping

To perform a ping to a remote host, issue AT+QPING=1,"8.8.8.8". This will yield:

+QPING: 0,"8.8.8.8",32,93,255
+QPING: 0,"8.8.8.8",32,78,255
+QPING: 0,"8.8.8.8",32,80,255
+QPING: 0,"8.8.8.8",32,80,255
+QPING: 0,4,4,0,78,93,82

Perform an HTTP GET

To perform an HTTP GET using the built-in HTTP client:

AT+QHTTPCFG="contextid",1
OK
AT+QHTTPCFG="responseheader",1
OK
AT+QHTTPURL=21,80
CONNECT

Low-power modes

While the BG96 supports low-power modes for eDRX and PSM, support for these features will vary by visited network and location. The commands to enable for each of these are:

  • eDRX: AT+CEDRXS
  • PSM: AT+CPSMS

Using these features, but especially PSM, can make the modem inaccessible to the terminal during its sleep time. It’s best to experiment with these features with the modem local. To disable all power saving, send:

AT+CEDRXS=0
AT+CPSMS=0

You can learn more about implementing these modes in our low-power usage documentation.
