What software are you using?

What Network are you using?

Where, exactly, do you see this error?

@PPraj.1​ "Software-STM32CUBEIDE"

I meant what LoRaWAN stack software are you using - presumably the I-CUBE-LRWAN, then?

https://www.st.com/en/embedded-software/i-cube-lrwan.html

Have you followed these videos for getting LoRaWAN working on STM32WL:

https://www.youtube.com/watch?v=vuc6914B0KM and 2 more following in the series.

"Network-IN865 band for lora network"

But what particular network operator; eg, TTN (The Things Network), SenRa, Tata, ... ?

"error see in lora portal"

Does their "portal" documentation give any help on this?

Do they have a forum?

Also, what target hardware are you using - A Nucleo board? Some other commercial board? A custom device?

Are you frequently restarting your target?

LoRaWAN Version -V1.0.3

Network Operator - Private Lora network using chirp spread spectrum technology.

We have used own Custom device making using STM32WL55JC chip.

You're really not helping.

@PPraj.1​ "LoRaWAN Version -V1.0.3"

That's the version of the LoRaWAN protocol spec - I was asking what software stack you are using to implement that protocol.

"Network Operator - Private Lora network using chirp spread spectrum technology"

So you have full control & visibility of the whole network?

"We have used own Custom device"

So have you tried with a known-working device?

I am using the STM32CubeWL Firmware Package v1.0.0 ( release date 28th Oct 2022)

This consist the 3rd Party LoraWan Middleware package as per below

LoRaWANV4.4.4BSD-3-Clause

V2.2.1ST release notes

For Network , yes we have full control on this.

For Device, We may check the Dev-Kit if available internally. Just to clarify we are just checking ST module manufactured by us with WL chip, there are no other peripheral or customizations. as you can see above.

Hope that answers your query.

Hello @PPraj.1​ ,

Can you try with LoRaWAN_End_Node example from the STM32Cube_FW_WL_V1.2.0 .

This example is located in "STM32Cube_FW_WL_V1.2.0\Projects\NUCLEO-WL55JC\Applications\LoRaWAN\LoRaWAN_End_Node".

You have to configure the example to your region IN865 in "lora_app.h" line42 and in "lorawan_conf.h" line77.

If you are still facing this issue, the error should comes from the network.

Best regards

Hello @Louis AUDOLY​ 

  1. According to you I have tried LoRaWan_End_Node example
  2. When I used ADR then i faced framocunt error
  3. When I not used ADR but default data rate then i faces again that error.

So you can explain there is network problem or not?

Also answer Why network Problem ? Give me specific reason for that.

I have added some photos of FrameCount error you can see(both with ADR and without ADR)0693W00000QLiy6QAD.png0693W00000QLixmQAD.png
