Error Initializing ESPNow

[grender007]

I'm using ESPNowStream and everything went pretty well until I updated the library today (The last time I updated the library was a month ago). I tried to upload my code (I didn't make any changes) and then I got this error:

I don't know why I got this error in the first place, because the code was working pretty good.
I also tried:
now_config.mac_address = "DC:54:75:C0:92:2C";
But it didn't work either.
I suppose the now_config variable is not accepting the address, but I cannot figure out why.

This is my code:
/**

• @brief We configure the audio codec ES8388 with the help of AudioTools I2SCodecStream.
• Then, we filtered the stream of bits using a second order IIR with FilteredStream.
• Finally, we send the stream of bits to a secondary ESP32-S3 using ESP-NOWStream.

Did you try what the error messages tells you to do ? Call addPeers before begin...

[pschatzmann]

Did you upgrade the ESP32 core ? What version are you using ?

[grender007]

3.0.0-rc1. Should I return it to 3.0.0 alpha?

[pschatzmann]

Double check, if this makes a difference ?
I remember having seen some open bugs around the mac address...

[grender007]

I got some progress! I still have the second error although I did what the error messages say. Sorry, I uploaded the wrong image.

[grender007]

Finally! I put addPeer after begin and it solved the issue. Apparently, the new core version is not compatible yet, but with 3.0.0 alpha works as usual!
