I’ve a problem with my particle: It seems that the internal antenna is broken (or never worked because it’s a brand-new photon) and it wasn’t possible to connect it properly to any network. So I purchased an external antenna and now it’s working. But sometimes when I want to flash a new code OTA it says “flash unsuccessful” but in fact the photon starts to flash/blink mangenta at the same time when “flash unsuccessful” appears (during 30sec-1min). When it’s working properly it says “flash successful” and mangenta lasts only for 10sec.
Why it isn’t working properly?
