Did you check the mobile app to see if the devices are now running Tinker now (or can you when you get any of them to come back online)? Have you checked to see if you have a serial port when one of your devices is plugged into USB?
Yea, same here, all have Tinker on them again.
Maybe the phone setup process loads the RC26 on setup now?
I have not tied Serial usb yet.
It seems to me that RC26 flashes RC25 (so no system updates) but with tinker instead of the selected application. Manually selecting RC25 was the only was to flash my own user code again.
I really would like to try the RC26 to see if it gets better … but where do you fin dit? For my account it’s neither in “build”:
nor on GitHub
neither worked by reinstalling the Argon from the iOS app (still RC25)… Am I missing something?
0.8.0-rc.26 is currently being tested and not available yet.
We spent several hours fighting with both Argons and Xenons with rc.26 showing up and disappearing. We also kept having the issue of losing the serial port so while you could flash new code, you couldn’t get any output via the serial port. If you put the units into listen mode, you could hear the serial port initialize and it appeared to be ok. As soon as you gave it wireless credentials, it would connect to the wireless network and then disable the serial port. If I hadn’t waited 9 months to get these new devices, I probably would have thrown them out the back door.

Are you using
Serial.begin(9600) in your
Is your user code doing some form of
Serial.print() and you are seeing that it does not show up in the serial terminal?
I saw this same thing after I tried to update to rc-26 (when it was present in the IDE and flashing Tinker to the device). I just tested again, and unlike on my Photon (on 0.7.0) which finds the serial port whether or not I have Serial.begin(), the Argon, on rc-25, only finds the serial port if there is a Serial.begin(). Has the use of that been made explicit? Given this behavior, it makes sense that we didn’t see the serial port after the attempted upgrade to rc-26, since it put Tinker on the device, and it doesn’t have a Serial.begin() in the code.
@kennethlimcp, yes, I am doing both the begin and the print.
The problem is that at the OS level the serial ports are not being initialized. When you go into the Device manager in Windows it says there are no serial ports available. If you go into CoolTerm it says there are no devices available. If you go into PuTTY it says there are no devices available. This problem didn’t start until the phantom .26 code started showing up sometime after lunch.
In fact, I had hooked up a uBlox M6 to my Argon and it was spitting out GPS data with no problem, and I was serial monitoring it with no problem. After lunch I wanted to move the uBlox to the Xenon and mesh it over to the Argon, which would then upload it to the Internet. That’s when I started seeing the .26 code become an option and things started breaking. Same exact code that worked before lunch broke horribly since the serial ports would not initialize. This happened with Argons, Xenons, and multiple laptops.
Have you reverted to rc-25?, because if you haven’t, your code with the Serial.begin() is no longer on your device, Tinker is (or at least that’s what happened to me when I tried to upgrade to rc-26). This re-flashing of Tinker is discussed in this thread.
@ric, yes I did, no change.
I was able to get the Argon back on-line by re-flashing the GPS code at .25. I tried doing the same with the Xenon but it still does the same thing: blinking blue with no wifi creds and the serial port active. Once I put in valid wifi creds it breathes properly but does not init the serial port, even with non-Tinker code.
After spending the whole afternoon I just threw everything back into the box. I haven’t had the time or patience to start on round 2. Just reporting my findings.
Looks like some could test RC26, so what are the criterias. I would like to test it, because i have nothing to loose, my all Argons and Xenons are unusable in this state.
@ninjatill, ok then i can wait a little, but if Particle is looking for early testers… i am ready to
I didn’t read this whole thread, but re: serial port – there was an intentional change for at least the mesh products (I’m no sure if this will make its way into the 2nd gen devices) where if you don’t have a Serial.* function call in your code, the serial port will not be initialized. I am curious to know why that decision was made but haven’t found out yet. If I do I will post here.
IIRC that was to allow for the more flexible USB control requests scheme which would be more “complicated” to achieve with an already “preoccupied” USB CDC interface.
But the engineers will know more to tell
I have the same issue. My Xenons connect to the mesh. They’re all breathing Cyan and I can Control them via tinker. After some minutes they’re flashing green and aren’t reachable anymore. I have to wait now until this issue is solved.
While you wait for the new version, if you want to have some fun, setup a new wifi network with your phone or with a pc that has wifi and ethernet (search setup mobile hotspot on windows). That should work for now
