Hi Rodrigo, I think Eduardo got it working on NuttX using PPPD, see:
https://github.com/apache/nuttx/issues/8147 It is important to know, because even Quectel support said the it wasn't possible to use CatM1 or NB-IoT with PPP: https://forums.quectel.com/t/bc95-g-ppp-connection-over-nb-iot-possible/12191 But of course the support guy was wrong and even in the modem datasheet comments that PPP was supported.
