Tutorial: Updating your E Series LTE Eval Kit to 1.0.0 or later


#1

Background

The E Series is Particle’s mass production form factor for the Electron, our cellular development kit. This purpose of this tutorial is to help customers using the E Series to update their hardware to the most recent version of Device OS firmware.

IMPORTANT: If you are setting up a new E Series LTE Evaluation Kit or E402 LTE module, note that there is a known issue in u-blox modem firmware that results in repeated handshake errors the first time the device connects to the Particle Cloud. Devices with this issue will typically flash cyan with intermittent red flashes for 5 to 30 minutes, after which the device will usually connect successfully.

To implement the Particle workaround that resolves this issues, please update your E Series LTE device to firmware v1.0.0 or later using the instructions in this post.

How to update using USB (recommended)

If you have not installed the Particle CLI you should do that first.

Connect the E Series board to your computer. Make sure you use the E Series USB connector, the one closest to the battery connector.

Put the E Series board in DFU mode (blinking yellow) by holding down RESET and MODE, releasing RESET and continuing to hold down MODE while the main LED blinks magenta until it blinks yellow, then release.

From a command prompt or terminal window:

particle update

How to update over-the-air

It is possible to upgrade your E Series Device OS over-the-air, once you get to breathing cyan and claim your device, as well. Note that it will take a long time (sometimes a half hour) to successfully get to breathing cyan using the device OS version that was installed at the factory, so upgrading by USB will get you online faster.

particle flash YOUR_DEVICE_NAME tinker-1.0.0-electron.bin

The E Series module will blink magenta and reboot 4 times but after the last reboot it should be running 0.8.0-rc.11. Note that this will use about 270 K of your 3 MB included data allowance.

Hi Will, Blynk just got a E-Series eval Kit.

Unfortunately, 3 hours later unable to connect it…
SIM was activated though.

firmware was updated (was it? – how to check current version?)

Device continue to blink green, sometimes stop and led is set to white, then blinks green again.

I can’t claim it through CLI or app. Device doesn’t show up in the list of devices

Could you please point to any troubleshooting guide?

Particle Doctor doesn’t help too:

particle doctor
The Device Doctor will put your device back into a healthy state
It will:
  - Upgrade system firmware
  - Flash the default Tinker app
  - Reset the device and server keys
  - Clear the Wi-Fi settings

The Doctor will operate on your Electron connected over USB
You'll be asked to put your device in DFU mode several times to reset different settings.

Updating system firmware

Put the device in DFU mode
Tap RESET/RST while holding MODE/SETUP until the device blinks yellow.
? Select Continue when ready Continue

> Your device is ready for a system update.
> This process should take about 30 seconds. Here it goes!

Flashing the Device Doctor app

This app allows changing more settings on your device

Put the device in DFU mode
Tap RESET/RST while holding MODE/SETUP until the device blinks yellow.
? Select Continue when ready Continue

Flash success!

Did you flash part2 and part3? You need to flash all 3 parts.

Also, do not use particle update or particle doctor, as they will revert your LTE device to 0.7.0 and it will not work.


#6

Ok,
Flashed all three parts. Device is breathing white (maybe it’s cyan?).
Apps still can’t see the device.


#7

So, after fiddling with the device for another few hours it only worked when I did
particle flash --usb tinker-0.8.0-rc.11-electron.bin
E-series was claimed and was finally seen in the apps and console.

However, it reset in a few minutes and since then it rapidly blinks cyan trying to connect to the cloud. Nothing helps. I re-installed tinker, but it didn’t work. Device continues to blink cyan.

Any ideas what can be done?


#8

Could you create a support ticket and include the device ID and ICCID of your E series?

You can use any of these techniques to find the device ID; the particle identify is probably the easiest.

Another option is to get a cloud debug log:
