The BATMAN mesh setup in FreedomBox is not very robust. You might be
able better off configuring manually from command line with this.

Network manager logs on why the first step failed would be very helpful
to debug.

The easiest solution would be to add a second Wi-Fi adapter to the
second FreedomBox. One adapter would connect as a client and the other
would be configured as a Wi-Fi access point.
