Hi, I’m planning on testing a mangOH Red device with a WP7702 module sending some information over cellular network. I want to test the difference between sending over LTE and 2G, but I’m not too sure how I can restrict the device only to use certain radio access technologies.

Thanks

This stuff looks promising: [http://legato.io/legato-docs/latest/c\_mrc.html#le\_mrc\_configuration](http://legato.io/legato-docs/latest/c_mrc.html#le_mrc_configuration)

I have never used that part of Legato though.
