CHAP/PAP authentication over LTE

I need to use the chap/pap authentication over LTE. I’m developing a firmware using the legato API. The functions used are: le_mdc_SetAuthentication to authentication and le_mdc_StartSession to start data connection. When the technology is LTE the data connection fails with LE_FAULT return code, but with UMTS technology the data connection is Ok. Is it possible to make it works with LTE?

did you try with “cm data auth …” command first?

You can also try to use at!QCPDPP command and the method here:

Hi jyijyi,

Thank you for your reply!

The at!QCPDPP command worked fine!
