I have two new Photons - one came up right away and has been behaving well, the other was being terrible at hopping on the WiFi. I was starting to think it had some sort of hardware issue after re-installing the WiFi credentials about 20 times, factory reset, etc., but today I installed 0.4.3 onto it via DFU (since an OTA update wasn’t going to work) and it starts up and connects every time (previously a few times it wouldn’t ‘cold start’ at all). The new high-speed green DHCP blink feature shows that it gets an address pretty quickly. No application on it yet, but Tinker is running nicely. Thanks!
Thank you for taking the time to report positive effects of the release! The firmware team have worked hard on that, in particular fixing some WiFi connectivity issues, so very happy you’re seeing the results of our efforts!
