I am developing a desktop app to help in working with AT commands called ATCommander, check: http://atcommander.io/
The tool works by sending AT commands via a serial port from your computer to a modem.
Right know it supports the AT command set for u-blox GSM/GPRS modules, so no SARA-N2 module yet.
To use it with SODAQ NB-IoT board for example, you would need to connect it to your computer via USB.
Does SODAQ NB-IoT board has a serial <-> USB interface?
Also I would like to know if such a tool would be useful for SODAQ developers so I could advance it to support SARA-N2?
Your tool looks promising
I think a lot of people would like to have one tool to send at commands to all the available radio modules.
The NB-IoT shield has a Serial interface.
You need a microcontroller board or an serial to usb converter.
We made a sketch for an Arduino Leonardo, M0 and Sodaq Explorer.
On this page you will also find the required AT commands and the differences between the commands in the old and new firmware.
Let me know if you need more information.
How do I know if NB-IoT network is available in my country? (Brazil)
Vivo should have an nb-iot network in Brazil.
You can contact vivo about the availablility.
Or contact u-blox to see who are active in your country.
Ublox contact detail can be found here:
