This is to inform you that whenever I try to connect bluetooth and wifi simultaneously with firebase it gives error like this

Do you search this topic before?

There are many topics about using WiFI and Bluetooth simultaneously working issues in the internet.

You can't use it simultaneously in Arduino framework due to it shared the same radio.

But you can enable to use both of them in different time, in case of WiFi connect to server in non-secure mode without SSL/TLS which your device has enough free memory to use by both Bluetooth and non-secure WiFi client.

With SSL/TLS as in Firebase server connection, the SSL engine required large memory approx. 80 - 100k while establishing the server connection and your device does not have enough memory to reserve for SSL engine to work.
