Hi @fwj, welcome to the Cayenne Community.

Apologies for the delay in our response – I’m tagging our LoRa expert @croczey here who should be able to speak more directly to this error message.

Hi,

I was able to add the LORAMOTE to TTN and get the data to mydevices.
I can see only RSSI and SNR shown in the Cayenne dashboard, not the actual payload.

As LORAMOTE is GUI configurable, i cannot format the data as per the cayenne format.

Please advise how to view the LORAMOTE Data, as semtech loramote is listed in the supported devices.

Hi @hvenkatesh

To start, the “Conflict” error message you saw usually means that a device with the same DevEUI has been added to an account already. We only allow each devEUI to be associated with one Cayenne account. If that was not the case, this could have been a bug on our end, which we will look into ASAP.

If you are only seeing RSSI and SNR values, this means that the payload is not being sent as expected. Can you please inform me of the mBed library and code that you used to configure the LoRMote? In addition, make sure that you are selecting the correct device from the device list, as the payload format for the LoRaMote EU is different than the LoRaMote NA.

Thanks!

Thank you Camrin.

I did not get the Conflict error message.

  1. MBED module
    There is no issue while working with Mbed module, as I can pass the data as per the Cayenne LPP format.

I have used LORAWAN code from
https://mydevices.com/cayenne/docs/#introduction

  1. LORAMOTE:
    But semtech LORA MOTE can be configured using the GUI, and we cannot modify the data format.
    It send the LED STATUS, GPS coordinates, Pressure, Temperature.
    As am unable to send in LPP format, only RSSI and SNR are reflected in dashboard.

Can we encode the data in TTN as per the LPP format?

  1. can you give more details on Data Channel, what does it means and how it is used while 5 different sensor data has to be sent.

Data Type value can be found from the Table on
https://mydevices.com/cayenne/docs/#introduction

We already have a payload decoder for this device, so you do not need to restructure the data. Just add the device as a Semtech LoRaMote EU as shown below:

Thank you.

LORAMOTE Sensors Demo is working well. Only GPS demo has issue.

hi @croczey
I got the same issue as I wanted to switch to Cayenne LPP to get more data than RSSI, using post from 6 maart 2017 by hansboksem.
I was first deleting my initial device (microchip Lora explorer by Sodaq which was connected fine) and when adding the Cayenne LPP as new device I got this same Conflict error message.
I’m now stucked as I can’t even create my sodaq device to come back to initial usage.
thank you for your support,

@planney

Sounds like the system thinks that your device is still active on the account, even though it has been deleted.

Try clearing your browser cache and trying again just to double-check. If that does not work, can you please send me the DevEUI of your device. With that, I can check our backend logs to see if maybe your device is in a weird state.

Thanks,

Camrin

Hi, I have the same problem with my sodaq one tracker.
I installed the sodaq tracker cayenne software and used the LPP configuration at the TTN end.
At Cayenne i have chosen the sodaq one as a device. (EU)
However only RSSI and SNR are displayed.
Can someone help with this issue?

Hi,
seems I got the same problem. I added a device with a certain DevEUI, then discovered that I made a mistake and deleted it. Now I can no longer add it, keep getting:

Please fix the following errors:

  • Conflict

Is there any possibility to remove the DevEUI from the Cayenne database?

Thanks, -pl

you need to wait atleast one hours after the removal of the device.

Thanks, that was a very helpful hint!
I tried and it worked.

Can i just regenerate the DEVEUI in TTN rather than waiting 1 hr to register?

15

you can add to cayenne but can you regenrate a new DevEUI?

16

i dont think you can change the DEV EUI once generated in TTN but i can always create a new device with new dev eui

17

well, it has been more than 1 hour so now you can add the device rather than creating a new deveui.

18

not sure if its strict 1 hr or a soft one but it took my device 2 hrs to go away from the registry.

19

well it depends on when the system last flushed the cache. so sometimes it does take time.

true i think its all about getting used to it :slight_smile: but creating a new device with new DEV EUI will take only few minutes just as a parallel option
