As per the examples provided by Fresscale, K70 can be interfaced to SIM900 which is a GPRS modem. Is it possible to interface K70 to SIM7250E which is an LTE modem that supports 4G and GPS.</P><P></P><P>Thanks ,</P><P>Sneha</P></BODY></HTML> Fri, 05 Feb 2016 11:53:54 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Interfacing-K70-and-GPRS-Modem/m-p/492754#M30448 snehahegde 2016-02-05T11:53:54Z Re: Interfacing K70 and GPRS Modem https://community.nxp.com/t5/Kinetis-Microcontrollers/Interfacing-K70-and-GPRS-Modem/m-p/492755#M30449 <HTML><HEAD></HEAD><BODY><P>Hi Sneha,</P><P></P><P>K70 is able to connect to GPRS modems which support PPP interface which is the case of SIM900.
