Nano MTQN-MNG3-B01 Device Guide 21
To properly power down the cellular radio, use one of the following methods:
1. Issue command AT+CPWROFF then either wait 40s or until 1.8v from the cellular radio goes low.
Processor pin PC5 (Mbed pin name MON_1V8) has 1.8v from the radio connected to it.
2. Hold pin processor PE_4 (Mbed pin name RADIO_ONOFF or MDMPWRON) low for at least 1.5s. 1.8v
from the radio should go low.
3. If neither of the above two options are successful, an emergency power down can be performed by
holding processor pin PF_3 (mbed pin name RADIO_RESET) low for 10s. As always, power down is
confirmed by monitoring 1.8v from the radio.
Configuring u-blox Cellular Radio
This MNG3 device uses a cellular radio that can operate on different carrier networks (not simultaneously).
You must configure your module based on your carrier network and application. This includes setting the
applicable MNO profile (based on carrier), RAT (type of technology you wish to use such as Cat M1), and LTE bands
intended for the application device within regulatory compliance. The module is not intended be used in the
factory-default setting.
Depending on your MNO profile, certain elements may or may not be available. Refer to the table for details.
Updates to MNO profile version :
Note 1: +CPSMS
Note 2: +CEDRXS
Note 3: +URAT
Note 4: +UBANDMASK
If your carrier network is not on the supported list of MNOs, you must set to Cat M1 mode and follow the
instructions per that scenario below.
The MNG3 model has regulatory approval to operate in the EU/UK. We continue to work for approval on other
networks. Refer to the Sara-R4/N4 series AT Commands Manual for the list of supported MNOs and other details.
Note: If your device is on +UMNOPROF: 0 (SW default), you do not have a network defined yet and must
set one.
To set or switch carrier networks:
1. Deregister the module from the network or perform an AT+CFUN=0 cycle:
AT+CFUN=0
