WalkthroughThe BSSID field now allows colon-separated and hyphen-separated MAC addresses. ChangesBSSID parsing
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Separated BSSID input can still be truncated and cleared when saved through the JSON configuration path, so the new format may not work for users entering colon- or dash-separated addresses. The buffer and copy limit should be updated before merging. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

getStringFromJson copy limit in the configuration parsing flow to at least 18
bytes, resizing the destination array if needed, so 17-character colon- or
hyphen-separated MAC values reach fillStr2MAC intact. Add regression coverage
that loads both separated formats through the JSON configuration path.

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 |
