Increase the JSON BSSID buffer to match the new format.
fillStr2MAC now accepts 17-character separated values, but wled00/cfg.cpp, Lines [98-115], still passes 13 to getStringFromJson for bssid. A value such as 9E:2A:6F:44:27:7A is truncated before it reaches this parser. The parser then sees fewer than 12 hexadecimal digits and clears multiWiFi[n].bssid.
Increase the bssid destination and copy limit to at least 18 bytes: 17 characters plus the NUL terminator. Add regression coverage for colon-separated and hyphen-separated values through the JSON configuration path.
Suggested fix
- getStringFromJson(bssid, wifi[F("bssid")], 13);
+ getStringFromJson(bssid, wifi[F("bssid")], 18);Also resize the bssid destination array if it is currently 13 bytes.

thanks. since the BSSID comes from the UI, why not clean it there? edit: see referenced commit in the issue |

deserializeConfig()copieswifi["bssid"]into a 13-byte buffer, so the JSON path truncates a 17-character separated address beforefillStr2MAC()receives it. The parser then clears the BSSID because fewer than 12 hexadecimal digits remain, soWiFi.begin()does not pin to the entered address. Use an 18-byte buffer and pass18togetStringFromJson()to retain the 17-character value and its terminator.🤖 Prompt for AI Agents
