Hey, I have a Photon laying on my desk connected to the local wifi. The problem I have is this It loses connection to the wifi blinks green searching for wifi finds wifi and starts blinking cyan locks up and never leaves the authentication phase I press reset and it does it all over again with th…

Hi @mdma - thanks for your response. I’ll need to put the obligatory newbie warning here, so bear with me… When I try to update the firmware online (using the CLI) I get: " I couldn’t find that: system-part1-0.4.3-photon.bin" To be clear on process, *I log on to the CLI (using email / password) …

That sounds correct to me! Thanks for working this through in detail. The intent was that this information would be in a wiki page so that we don’t have to repeat it for each release. I’ll update the wiki based on the level of detail in your notes so that everyone is clear on the process! :+1:

OK, maybe off topic here but when trying the DFU mode update I keep getting: Opening DFU capable USB device… Cannot open device I have updated the drivers for photon and device manager sees it as Photon DFU Mode, though there is a little yellow sort of exclamation symbol next to the icon. Any idea…

@DRCO , the triangle means the driver is not working. Did you install the Zadig driver as per the documentation?

I believe Homer Simpson would have said, : “Doh…!” Thanks Peekay123 - seems to have worked.

[image] Switching Between Chip and u.LF antenna The default mode is auto where it selects the strongest signal, so you should be able to simply plug in the antenna. This was a response to me asking if the antenna will work on the Photon. Is this incorrect?

[quote=“peekay123, post:4, topic:12321, full:true”] @DRCO , the Photon does not auto-detect the antenna. The (soon to be released) firmware update has a command for switching the antenna. [/quote] asking because of this

Hi @mdma , Just wanted to confirm that I only download the two relevant photon.bin files - and run the commands as described in the github repo. Thing is, while I had no problem running them from DFU, I can’t seem to connect the Photon via USB / CLI for wifi setup. I keep getting: C:\Users\xxxx\Des…

OK, just an update - but the DFU upgrade made no difference. The Photon is good for about 15 minutes, then goes into constant rapid blink cyan - same as before. Does not recover. I have a Core working fine in the same position. Unlike the Core I have run Blinky as a test program on the Photon, that …

@DRCO , I've started using this code to deal w/ my photons losing their grip on the cloud: [image] Microwave hardening Troubleshooting So the problem in the photons (loss of cloud connection, rapid cyan blink, but generally not on the spark core) keeps intermittently occu…
