Good but not for CAN sniffing
For Freematics ONE+ - ESP32+OBD+GNSS+LTE
I think this is a fantastic product if you only care about basic OBD2 information and tracking vehicles.
The product page states "CAN bus data sniffing" but in my experience the chipset is an ELM327 variant that is not able to cope with more than a few messages before it gets overwhelmed - appears to work OK if you filter to a single CAN ID with the masks but disabling filtering is a no-go.
