After a very pleasant experience of getting your advice, I would like your input on another issue.
I require a reliable, MCU driven cellular module to purchase in bulk, for a single purpose: communication with a remote server over HTTPS (so SMS, audio calls, etc. are not unnecessary)
I would like your recommendation for a specific model / line of products / manufacturer
A basic module will do, it just should fulfill these requirements:
1. 4G + LTE
2. able to communicate over HTTPS with a remote server
3. preferably a reputable manufacturer and not nigh-discontinued :)
4. reliable (IoT, will be left alone far away from its handler for prolonged periods of time)
5. GPS is a plus
6. WIFI is a plus
Do you have any suggestions?
