FCM OAUth2.0 with Ethernet not work

[back920096]

hello author I would like to ask how to use firebase FCM OAUth2.0 with Ethernet I am using esp32s3 Irebase FCM OAUth2.0 can be used normally when I am on wifi Ethernet doesn't work

I assumed that you mean HTTPv1 API cloud messaging. This library does not support that, only legacy API supported.

You should use this library instead.

If you already used that library, you post in the wrong repository.

For ethernet with native support PHY (e.g., LAN8720) please follow this example.

For other SPI ethernet module (MAC), please use external client by follow this example and this example.

When you use external ethernet client, it is not in this library scope, and you should debug your ethernet client yourself.

[mobizt]

You should post your code or create the simple code to replicate the issue and describe more error details.

But won't the old version of FCM stop serving next year?

I have no idea. You should ask Google supports.

Hello author, I would like to ask if there is any way to get the Bearer token in the esp32+w5500 solution? I plan to send FCM via http after getting the token I refer to https://github.com/mobizt/ESP-Signer I want to get token through this project Create an account according to the process and implement it but it is not successful Here is my code and error message

Thank you very much for your help [image: image.png] /**

You don't need to use ESP-Signer library.

You can update the library to latest version 4.3.18.

And please don't forget to define this macro in FirebaseFS.h #define FB_ENABLE_EXTERNAL_CLIENT

Then try this example.
