Thanks

Is it updated? Can I re-download the library?

[mobizt]

Yes, you need to delete the old one and download new zip file from this GitHub. Arduino library manager was not the latest version.

Ok

[arushgupta2007]

Thanks man, your library has saved my life 👍 :)

Hi Mobizt. I am using Firebase ESP8266 Client Version 2.8.5. but I am still getting this "No device token provided" message. Which version should I use to get rid of this error? Thanks.

The issue was fixed since v 2.1.2.

See the fcm example

Thanks for the reply. I used the wrong function to send the topic. Your example does not show how to send a topic. After some experiments, it works now. Thank you.

You need to read the doc rather than ask for everything
