[Resolved] Photon doesn't report MAC address (stops responding after 'm' command) and doesn't connect to cloud

[lucasrangit]

My Photon doesn’t report its MAC address.

When in Listening Mode (flashing blue LED) running photon setup yields the error Potentially unhandled rejection [2] Unable to find mac address in response (WARNING: non-Error used).

When in Listening Mode, sending ‘m’ over serial yields Your core MAC address, with nothing else printed . Photon stops responding after this (e.g. sending ‘i’ to get device information does not get a response).

I tried configuring the WiFi over serial (option ‘w’) but still could not read the MAC address. The Photon never stopped blinking green (Connecting to WiFi network).

The Photon-XXXX SSID can be seen by the Particle Android app but it also never successfully connects (tries indefinitely to connect)…

Is this a totally new Photon that you are trying to setup? There’s some issues with serial and a system firmware update can resolve that.

Or try this: [Howto] Setup photon if docs step fail

Yes it is. Should I clone the "develop" branch from GitHub - particle-iot/device-os: Device OS (Firmware) for Particle Devices and build the system-part?-?.?.?-photon.bin? Or is there a pre-built binary available?

Or try this: [Howto] Setup photon if docs step fail - #10 by christine

I tried using particle serial wifi (previously I used a serial terminal manually) and the Photon is stuck at the "Connecting to Particle Cloud" step (blinking Cyan).

[kennethlimcp]

No you should not use develop. The stable branch is latest but a user should not need to go to that extend to get a Photon running.

Does it keep blinking cyan? any other colours?

The pre-compiled binaries are on the github releases page to save you having to setup a local toolchain.

[lucasrangit]

@kennethlimcp

Does it keep blinking cyan? any other colours?

Blinking cyan only. I know it's connected to the WiFi router; it blinks green before blinking cyan and I can see the device's MAC address on my router's status page.

[lucasrangit]

Now, if I power cycle the Photon, it will alternate (randomly) between high-speed flashing cyan and red before going into fast cyan. I have not changed the firmware.

I used the pre-compiled binaries referred to by @mdma and the following procedure.

1. Put Photon in DFU mode

6. Pressed the RESET button.

The Photon reset, reconnected to the WiFi, and again occasionally high-speed flashed red and cyan before simply flashing cyan indefinitely.

[kennethlimcp]

Ok it sounds like the core is unable to connect to the based on red flashes.

I had this issue before.

Try this:

• download: https://s3.amazonaws.com/spark-website/cloud_public.der
• place Photon in DFU mode
• dfu-util -d 2b04:d006 -a 1 -s 2082 -D cloud_public.der

[lucasrangit]

@kennethlimcp

download: https://s3.amazonaws.com/spark-website/cloud_public.der

place Photon in DFU mode
dfu-util -d 2b04:d006 -a 1 -s 2082 -D cloud_public.der

Can you tell from this output if dfu-util was able to flash that file?

hmm…not 100% but looks ok to me. How’s the Photon behaving? Was it claimed already?

[Hootie81]

@lucasrangit it looks like you are using a very old version of dfu-util, you will need to update to 0.8 to get it to work properly

[lucasrangit]

@kennethlimcp

Same results. Blinking cyan. No, it's not registered, as far as I know it's brand new.

@Hootie81

@lucasrangit it looks like you are using a very old version of dfu-util, you will need to update to 0.8 to get it to work properly

You're right. I'm using Ubuntu Linux 12.04 64-bit. I used the following to upgrade the software.

1. $ wget https://launchpad.net/~tormodvolden/+archive/ubuntu/ppa/+files/dfu-util_0.8-0~lucid_amd64.deb

2. $ sudo dpkg --install dfu-util_0.8-0~lucid_amd64.deb

3. $ dfu-util --version

4. Put Photon into DFU mode

5. $ dfu-util --list

10. Pressed RESET

11. Still no luck.

12. Performed Factory Reset

13. Now, Photon responds to $ particle serial mac with MAC address and without hanging.

14. Reconfigure WiFi with $ particle serial wifi

Still no luck connecting to Particle Cloud.

Would it help debugging if I installed an Ethernet packet sniffer?

Okay, here's a Wireshark packet capture showing the Photon aquiring a DHCP lease and connecting to the Internet.

I tried my home router, my phone, and a Raspberry Pi access point. Regardless of the router, the Photon does not pass the blinking cyan state.

Please reset the photon then look at the LED carefully, does it ever get to fast blinking cyan? If so, look carefully, do you see brief intermittent flashes of red or orange?

[lucasrangit]

@mdma

Yes, the photos intermittently flashes red and cyan at a higher-speed. It has been doing that since the beginning. For about 2 minutes there are a few short bursts of high-speed cyan, then fewer high-speed red. Then a few minutes of just fast cyan, followed by a single longer burst of high-speed cyan, then again shorter burst of high-speed red, until finally the Photon rests at blinking cyan.

The only change in behavior since the system firmware update is that I can now report the MAC address over serial using particle serial mac and the serial terminal using 'm' and it does not lock up the serial port.

[mdma]

It sounds like you need to flash new keys.

Photon setup flashing cyan with a "quick red burst" (now orange burst) [Solved]

most of my photons have gotten setup without a problem (go team!) but one is having a weird setup issue. the iphone app wont set it up (same problem as shown in the video) and doing this via serial has the same results. once i provide the wifi credentials, it flashes green, then cyan rapidly, with a very weird super quick burst of red/orange light. here is a video…
