RCF 7710 DHCP OPT reference #5
Description
Not an issue actually, but might be useful to leave a reference here.
An optional feature to make RCF 7710 DHCP option for capt portal detection support was implemented in ESP-IDF not so long ago.
Almost useless with Arduino since it has lwip prebuild, but might worth to have a link around for future.
Cheers!
