ESP32 Firebase Library Authentication Data Types not working

[dartronixeng]

Hi. I upgraded to the latest library. My previous version which is a bit old allowed me to sign into firebase with the following command firebase,begin(fbHOST,fbAUTH) where fbHOST and fbAUTH are char arrays with 64 elements each terminated with a null character. This worked great because the end user would populate this field via a BLE app based upon the account being used.

The new library command is set up as Firebase.begin(&config, &auth) where the two values are populated with config.signer.tokens.legacy_token = DATABASE_SECRET; and config.database_url = DATABASE_URL; where DATABASE_SECRET and DATABASE_URL are fixed values in a #define statement such as #define DATABASE_SECRET "12345ABCDefg".

How can I dynamically change the url and secret key values to connect to different firebase accounts and not have them hard coded into the ESP32? I have tried several different approaches and get errors upon compiling. Every attempt generates an error that it is not a string.

Thanks

You should post the complete compilation error for what wrong with your code because that is impossible for that simple thing that should not be happen otherwise you are trying to do something that is forbidden the C++ rules.

I think the error is coming from I am not sure the proper method to call the function. If I have two character arrays that represent the URL and the Secret, how do I apply those to the commands config.signer.tokens.legacy_token = and config.database_url =?

All of the examples show the value in quotes (a string) that is defined in #define. I am using character arrays.

For example, the ways your libraries demonstrate the following is

#define DATABASE_URL "test.firebaseio.com"
#define SECRET "abcdefg"
config.signer.tokens.legacy_token = SECRET;
config.database_url = DATABASE_URL;

In my use I have the following
char fbHOST[64];
char fbAUTH[64];

The two arrays will get populated during the runtime from an external BLE app. So I would have the following
fbHOST would contain test.firebaseio.com and a NULL character
fbAUTH would contain abcdefg and a NULL character

How would I apply these two arrays to
config.signer.tokens.legacy_token =
config.database_url =

so when I call Firebase.begin(&config, &auth) it will work

It supported all kinds of null terminated string. If compilation error, you should post the error here.

I will try it again. Maybe I had a typo or something. Thanks for replying.
