We experienced something weird for the first time in the field while flashing an update over the air to a Photon (running 1.5.2).
After flashing firmware from the Web IDE, the flash starts in the console, and the photon starts blinking magenta. Then after a couple of seconds the led goes solid magenta and we can only recover the photon by resetting it (reset button).
-Flashing same app, same device in the lab (i.e different network) is successful.
-Flashing same app, different device in the lab (i.e different network) is successful.
-Flashing same app, different photon, in the customer’s network fails. The photon get’s stuck in solid magenta.
Could the firewall in customer’s network be blocking specifically the OTA? In normal operation, the photon in customer’s network works perfect (breathing cyan) so the firewall is not blocking normal traffic.
I’ve tried to read similar topics in the forum but they’re very old. I read that solid magenta happened in the past when data messages during the flash were lost in the transmission, so I wondered whether something similar is happening here but not on particle’s servers but on customer’s network.
Thanks for the advice.
