Google Cloud Database

I have 2G GSM Module SIM808 which supports HTTPS using SSL but doesn’t support TLS. I am trying to connect to HTTPS website but in return HTTP code 606 is received. So how do we directly or indirectly connect the GSM module to Google Cloud so that it can access firebase and update/get entries in the database.

Is there any other way in which we can communicate with Google Cloud services using HTTP and then those services internally communicate with Firebase , just assumption as No experience with GCP

The following tutorials give you some ways to connect your device to Cloud Firestore:

  1. IoT in Google Cloud Platform.
  2. Internet of Things prototyping with Firebase: how to do more with less.
  3. Using Firestore with IoT Core for device configuration.
  4. Tracking assets with IoT devices: Pycom, Sigfox, and Google Cloud.
  5. GSM & Arduino Communication with Firebase or Thingspeak.

You also need to learn about IoT Core, which is the starting point to connect your IoT device to GCP.

Regarding HTTP code 606, you can look at this Stack Overflow case and this GitHub thread to understand it. Your device is probably obsolete.
