I’m currently planning to add firmware support for the SIM7600. Not sure which final modem module we will choose - the initial firmware support is simply proof-of-concept. I like the idea of NB-IoT, and have played with SIM7020 (no GPS/GNSS though). The SIM7000 looks interesting (LTE, NB-IoT, EDGE, and GPS/GNSS).<br class=""><br class="">Regards, Mark.<br class=""></div></div></blockquote><br class=""></div></div></div></div></body></html>
