Seems to connect to WiFi OK (flash green / solid green) but then after a brief white flash it goes into fast flashing yellow for about 20 secs interspersed with medium cyan flashing for about 4 secs and then fast cyan for about 1 sec before back to yellow fast. Sometimes I end up in continuous medium flash cyan. iOS app doesn’t locate it and I can’t manually claim it either.
I was trying to ascertain if it was successfully getting a DHCP address - how do I know the MAC address ? Or any of the manufacturers fixed allocation part of the MAC would help. Does a failed DHCP acquisition give a special light sequence ?  It did successfully get a DHCP address… for anyone else looking the MAC starts 08-00-28- for Texas Instruments
I don’t think I’m quite the same as the other categories of problem posts (flash orange) - or am I ? Is a factory reset something I should try ?
