ESP32 Forum

Hi guys, after a while, I decided to go for ESP-IDF since it has a library for Google's IoT core platform.

My question is: Can this library work with a SIM900 or any LTE connection?

My project requires both WiFi and LTE connection, and if the lib doesn't support that type of connection, is it wise to go and build my own library using the HTTP REST API they provide?

Hi,

It should work with esp-google-iot.

For the LTE modem, you will need to use the pppos_client.

So I can have WiFi and LTE connection in the same project with the PPP client?

Hi,

I've never tested LTE and WiFi.
I think you can, but not sure about using it simultaneously. Maybe you'll need to implement some coex function in order to avoid issues.
