CubeCell Configurator

sronan · December 11, 2019, 6:09pm

Ah, thanks, both.
When I turn the sensor around to face the opposite way and move it so it fits in the back four headers on the left in the picture, leaving the first one in front empty, in the configurator I now see:
Scanning…
I2C device found at address 0x68 !
Found MPU9250

But it stops right there… no reference to LoRaWan Class A start! no reference to joining…
No traffic on the TTN console

Any further suggestions would be much appreciated…

rsmedia · December 12, 2019, 6:03am

Found a bug in the mpu code. I will upload new firmware today.

rsmedia · December 12, 2019, 2:32pm

@sronan: new firmware uploaded.
if you have time please try again

sronan · December 12, 2019, 4:04pm

Ah, it gets much further now… but hasn’t yet joined…

I set it to US 915 and selected Flash Firmware
I saw 10/100, 20/100 etc in the command prompt and in the configurator saw:

Downloadind Firmware …
Downloadind Firmware done
Flashing Firmware …
Flashing Firmware done
CleanUp Starting
CleanUp done

Then I selected Connect
I ensured that the DevEUI AppEUI and AppKey correspond to what I see on TTN and set the duty cycle to 0,15,0 and select write and in the configurator see:

AT+DevEui=003981B550BD22EA
AT+AppEui=70B3D57ED00269A4

======================

However, there it stops… I don’t see a join request when looking at the US915 gateway traffic…

hi can you flash it again?
i have found a failure in my script for compiling all the firmware for the different frequencies.
the frequency bands are not right compiled.
i have fixed that now

sronan · December 13, 2019, 1:52am

Sure! But now, after I reflash the firmware and then connect and enter the user data (DevEUI, etc.) and duty cycle and try to write it, it just gets this far:

AT+DevEui=003981B550BD22EA
AT+AppEui=70B3D57ED00269A4
AT+AppKey=B423D01003D3F1A1B932C2A7CD027990
AT+DutyCycle=900000

AT+RESET=1

And then stops. And if I then disconnect and connect again, the DevEUI, etc. are blank.

rsmedia · December 13, 2019, 9:01am

arduino-cli has some issues compiling the firmwares right.
thought i could script the build process for the different frequency bands and options
but the arduino-cli is making something really wrong.

back to compiling by hand.
a new compiled version for us915 band is online now.

heikkij · December 13, 2019, 11:10am

Curious: what are the firmware fixes for ?
Also: I’m using a mac, will the configurator run in a VM ? Or is there another way to update the firmware ?

rsmedia · December 13, 2019, 11:33am

The last fixea are only little typos.
The conhigurator should be running in a windows vm.
If you would like to compile on your own you can use the manual here:

github.com

HelTecAutomation/ASR650x-Arduino/blob/master/InstallGuide/mac.md

Installation instructions for Mac OS
=====================================

- Install latest Arduino IDE from [arduino.cc](https://www.arduino.cc/en/Main/Software)
- Open Terminal and execute the following command (copy->paste and hit enter one by one):

  ```bash
  mkdir -p ~/Documents/Arduino/hardware/CubeCell
  cd ~/Documents/Arduino/hardware/CubeCell
  git clone https://github.com/HelTecAutomation/ASR650x-Arduino.git CubeCell
  cd CubeCell/tools
  python get.py
  ```

- Restart Arduino IDE

Excellent progress! It’s now joining and sending data successfully… Though the payload may not yet be quite what it should be?

We are getting better
I will have a look this evening.
My mpu sensor is still on its way so i cant test.

Hipe to have a new functional version this evening

heikkij · December 13, 2019, 2:58pm

@rsmedia, thanks.
Btw, the CubeCell Configurator works well in a VM so I’ll stick to that.

rsmedia · December 13, 2019, 5:03pm

@sronan uploaded a new US915 firmware. hope the MPU is now not only detected but will deliver values.

And then it stops…

Then at TTN I see some traffic… but normally no payload… the dev addr keeps changing…

But on just one occasion… I think as I disconnected at the configurator, I suddenly saw a full payload delivered including this data:
{
“aSqrt”: 0.9949142336845398,
“aY”: -0.88330078125,

}

See attached image of it suddenly appearing in the middle of this screenshot

sronan · December 14, 2019, 3:02am

I reflashed again… and rewrote the user data

I now see this in the configurator

Looking at gateway traffic I at first was seeing a long series of join accepts which is what each of these is:

Apparently that explained the dev addr changing each time.

But now the dev. addr. has stabilized and I am seeing some legitimate payload data…

Had a potential professional group test the cubececell capsule today using the configurator designed by @rsmedia

Geographical region: US
This is the output of the debug screen:

Downloadind Firmware …
Downloadind Firmware done
Flashing Firmware …
Flashing Firmware done
CleanUp Starting
CleanUp done

AT+DutyCycle=900000

AT+RESET=1

Please note the following when reading @rsmedia configuration guide
Under the CubeCell Configurator for configuration, section Use CubeCell Configurator for configuration please read as follows

a. Go to TTN, and create an application if you haven’t already

b Under your application create a device for the CubeCell device you are setting up

c. copy the keys: Device EUI, Application EUI and App Key

Please note that you should copy and paste only one key at a time. On TTN you will notice that there is a Copy icon at the end of each key field. Then back in the Configurator screen just paste each value you copied from the TTN device screen

d. Once those three values are entered, click on write

e. The keys will be saved in the CubeCell device and the device will reboot
If you click on the Debug type you should see the above log entry - last line should read
AT+RESET=1

The guide does not say what is supposed to happen or what you should do next

Any pointers: the 915 MHz capsule is connected to a USB board connected to Com15 of an HP PC
TIA

sronan · December 14, 2019, 3:13pm

As per my message here:

just yesterday (December 13) I had results similar to what you describe and subsequently a new version of the firmware was developed.

Could you try again now?

I’d add to your excellent, clear outline of procedures just a reminder to select the right frequency (e.g., US915) in the Configurator.

rsmedia · December 14, 2019, 1:21pm

thank you @[Gipsyblues
just updated the guide to make the needed steps a little clearer.

Please note that the version of the configurator ist not the version of the firmware.
The configurator downloads allways the newest firmware.

Gipsyblues · December 14, 2019, 5:38pm

Thank you guys for your prompt responses - @rsmedia and @sronan in particular.
@sronan, the configurator software I downloaded was only yesterday night, so I will assume that it is the latest .

Also you should know that I did test the Configurator software using a CubeCell dev board and the software worked perfectly! So the issue has to be with the CubeCell capsule I am using for the test

One thing I noticed, BTW I am using a Windows PC, when I used the dev board, the DOS window shows a complete count down/up of 10, 20, 30, etc. However with the capsule the DOS windows closes before the count down/up.

I intend to try the capsule setup again and hopefully report the results.

Once again @rsmedia, thanks you for your fantastic work. Just another comment: could you please fix a typo in the debug messages. the word downloading is spelt as “downloadind” it should be corrected to downloading - ending with a “g” and not a “d” . Please pardon my comment, too many years of spending time in the air force and teaching at a college make me do that:smile:

rsmedia · December 14, 2019, 6:24pm

Will fix the typo later today. Thank for reporting @Gipsyblues
Will take a look why the firmware write for the capsule does not work as intended. I am right now in berlin and took only a dev board with me. All capsule are left at home.

Please keep in mind that the version of the configurator has nothing to do with the firmware version.
The newest firmware is allways downloaded before flashing.
