Using SIM7000G with IDF

[DavidDan]

Hello,

I'm using LilyGo T-SIM7000G, and I'm trying to use the SIM7000G modem to send SMS's and post HTTP/MQTT packets to the cloud, and I can't find code that actually works on the SIM7000G (I tried using PPPOS, but it didn't work, and I also needed more documentation).
I really need some help here.

Thank you!

Not sure if this will help you get closer.

PPPOS works fine, or at least did before most recent change, with SIM800L and BG96, so i am guessing it should works with SIM7000 too.
The thing is that different LTE modules have some specific requirements which is not included in example. For example BG96 needs delay UART comm about 5 or 10 seconds after reset (not always, but its recommended by producer). I think that espressif example is assuming that LTE module is already connected to LTE network, because there is no code to use reset and power key pins (on BG96).
It is always recommended to read hardware specification before use it with espressif examples. I am not saying examples are bad, just some assumptions are made that cant be done in real life app.

BTW pppos is really great stuff, its my first project with it and i love it

Hello, I have the esp32 sim7000g from LILYGO, and I am also looking for possible examples to use the ESP-IDF instead of the Arduino IDE to be able to obtain GPS information and send it using a GSM or LTE connection. Does anyone in a similar situation have any information?

Thank you!

If any of you guys are still on the matter, I have SIM7000 and lilygo working with pppos but I have a different issues found on this thread:

Please exchange opinions when you can.

Thanks in advance

Hi, could you give me some advice, I have been having trouble using the sim7000g module. But I can't get it to work, if you can help me with a guide for the configuration of the dte module I would be very grateful. Regards.

Hello, I am also trying to use sim7000g with esp_modem but it is proving impossible (for gprs connection and obtaining gps data). Has anyone got it?

Thanks.
