+Both the 16.0.1 and 14.5.1 Apollo builds broadcast an **open** hotspot, not the stock WLED
+`WLED-AP` / `wled1234` pair. The string `wled1234` is absent from `M-1_full_install.bin` and from
+`Apollo_M-1_Rev6_14.5.1.bin`, while the sibling default `wledota` is present in both, so `apPass`
+is empty. The m1-b8 release notes state it directly: "STEP 1: join the open Apollo M-1 WiFi", and
+list "cleaner hotspot name: the setup WiFi is now just Apollo M-1 (no serial-number suffix)" as new
+in that build, which is why step 3 says older builds carry a suffix. Setup address is 4.3.2.1.
