How do I switch between LTE-M and NB-IoT using AT commands?

LTE-M / NB-IoT (Monarch)
1

Hello there,

I saw there’s an existing AT command to switch between both modes. My main question I guess would be whether I need to reboot while switching from one mode to the other. Is there anything else I need to take care of?

Thanks!

Dear Brian,

It is possible to switch from LTE-M to NB-IoT mode (or vice-versa) using the AT+SQNMODEACTIVE command. The module must be rebooted to activate the new mode.
It is currently advised to reconfigure the bands to be scanned with AT+SQNBANDSEL after switching between LTE-M and NB-IoT modes.

You can refer to the following documents under cloud.sequans.com

In the GM02S folder:

  • the application note Monarch2-ModemAppBasics-Rev.4.pdf in section 14.5
  • the AT command reference manual: Monarch2-ATCommandsReferenceManual-LR82-Rev.3c.pdf in section 6.1

Thanks
