I just wanted to give an update to my situation, as it relates to this topic.
My Argon will not connect to my home wifi using the ios app - it always results in rapid green blinking. It will connect to my iPhone’s Personal Hotspot wifi, resulting in breathing cyan, and I can publish events et. al. only when it is connected to my phone acting as a hotspot.
My home wifi is a TP-Link Deco M5 mesh network. It has both 5GHz and 2.4GHz networks both using the same SSID and credentials. IPv6 is disabled. The password is “Abcdefghi1”. When trying to connect to this network as is, after selecting my network from the ios app, the Argon switches to rapid green blinking, the ios app tells me the bluetooth connection was lost, and I need to do a factory reset on the Argon to get it back to blue blinking listening mode.
I added a guest network on my home wifi and turned off the 5GHz, so it is 2.4GHz only. It has a different SSID then my regular network, and the password is (was) “abcdefgh”. IPv6 is still disabled, and the Argon is unable to connect to this network either. Same results as before.
So I am unable to connect to my home wifi using the ios app.
