Hi. The steps I do are these:
1-I turn the bulb on and off 5 times until the bulb changes color several times and goes blank. (reset the bulb) The bulb remains blank waiting for the configuration.
2-With the mobile I open the app (I tested connected the mobile to the router and also using another phone as a hotspot), I put the password to the network to which I am connected, then I see the AP that begins with yeelight-xxx. I connect to it and the application starts trying to connect to the light bulb.
3- in the application, the configuration does not exceed 25%. After a while, there is an error message in which it says that it could not connect and try again.
I have tried many times, with different phones, (iphones and android). I've also tried to wait more than 2 hours since physical poder off (I left it all night and the next day try) and it does not work.
Before the last update, when I had to configure the bulbs, I had no problems and they were configured the first time. It has been updated to the latest version, and I can not connect them to the iPhone (and therefore, not turn them on or off from the phone, change the color ...) They have remained as normal bulbs without wifi. Thank you in advance
