If you are using the Botletics SIM7000 shield, please make sure you have a LiPo battery attached with the proper polarity (red wire should be on the left side of...

Sorry, I've never really used ESP-IDF with Arduino. Are you using it so that you can include the IDF commands inside Arduino IDE? Are you saying that simply installing ESP-IDF...

What firmware version do you have? It's possible that if you had an older version, the AT+CNMP command is being reset. YOu could also try checking "AT+CNMP?" after it reverts...

LTE CAT-M is not the same as traditional LTE, and using a typical LTE SIM card that is in most smartphones will likely not work.

You don't have to do anything special. If you just compile for Arduino Uno or Mega without adding any libraries, it should work.

Yup, low memory with the Arduino Nano is the major suspect here. If you're going for a compact form factor, there are other alternatives that have much more memory, like...

It may work, but you just have to keep in mind your goals and think about what you might add to the code later.

Are you still having this issue? If you want, you can always use a simple timer with `millis()` so that the code isn't blocking with the `delay()` call.

Correct, HTTPS won't work on that without upgrading firmware. The v6 version comes with 1351B03 for the SIM7000A, 1529B01 for the SIM7000G and 1351B05 for the SIM7000E. The SIM7000G one...

So you're using the SIM7000E? If you get the [SIM7000G shield on Amazon](https://www.amazon.com/dp/B07H3YNCQS/ref=cm_sw_r_cp_awdb_t1_qAikDbXXPCWV8) it will for sure be version v6. I'm verifying with SIMCom which firmware versions support HTTPS.
