Sim7000g without Arduino (ESP-IDF) #196

Open dgomlopez opened 1 year ago

dgomlopez commented 1 year ago

Hello,

do you know if it is possible to somehow make the sim7000 (gsm + gps connection) work correctly with the esp-idf?

With Arduino it seems to work fine, but trying to replicate that functionality in the ESP-IDF is getting quite complicated.

I am trying to use esp_modem as a component of ESP-IDF.

Any help is welcome.

Thank you!

Trying to do the same. Adding esp_modem was possible by adding list(APPEND EXTRA_COMPONENT_DIRS esp_modem) within the toplevel CMakeLists.txt. For now I am stuck with the pppos_client example, which is not using the gprs features. Did you (@dgomlopez) found a way to solve your problem?

EDIT: I am using platformio

Hi @pixelskull . I can use esp_modem as a component, but I have not been able to connect to the network or use the gps. esp_modem in principle works with sim800 and sim7600 (I don't know if completely, network + gps), and it seems that it has sim7000 components but it doesn't finish working.

@dgomlopez Same here, I run into error code 263 - which seems like a timeout. Sadly I can't help you, but maybe we can get an answer together through this issue. You are using the pppos_client.c example as well?

Hi @pixelskull I try to use now this example: https://github.com/espressif/esp-protocols/tree/master/components/esp_modem/examples/simple_cmux_client esp_modem 0.1.24 (last version). This example include sim7000 support but dont work apparently.

I'm try to use ppos-client.c too, but dont work for the moment.
