Unable to connect Lora Wio-E5-dev kit to The Things Network console using STM32CubeIDE

[Prasadh_004]

We tested LoRa wio e-5 using AT factory firmware initially and it worked fine with TTN and gateway.Now after erasing AT firmware and using STM32CubeIDE we are trying to connect wio-e5 dev kit to the things network LNS with our sensecap m2 gateway which is also connected to TTN and sending data, but our wio-e5 is not connecting to TTN application server. We followed the seeed studio github and seeed studio docs  for this. We have set our dev eui, join eui, and appkey in the macros of se-identity.h file in STM32CubeIDE according to our generated TTN application server details.

LoRa wio-e5 configuration:

it uses STM32WLE5JC Mcu with SX1262 RF chip 

STM32 configuration:

Package: Lorawan_endnode_main (with HAL for STM32WLE)
Mode: OTAA
Region: EU868
Low power mode: disabled

TTN end device configuration:

Frequency plan: Europe 863-870 MHz (SF9 for RX2 - recommended)
LoRaWAN version: LoRaWAN Specification 1.0.2
Regional Parameters version: RP001 Regional Parameters 1.0.2 revision B

We didn’t modify anything in the se-identity.h other than the above mentioned EUI id’s.
Problem:
Wio e-5 is not joining the TTN network even after correctly following all the steps mentioned in the seeed studio’s github documentation

Any suggestions on how to solve this issue?
Thanks in advance for the solution.

Hello @Prasadh_004 and welcome to the ST Community.

You are using is a third-party module based on an STM32WL MCU with the example code provided by our third party. 

So, I suggest you to contact our third-party throw his community on this link. 

Best Regards.

If you revert to that firmware, does it work again?

Can you get any diagnostics from your gateway and/or TTN?

[Prasadh_004]

it is factory at firmware which can't be reverted back

and for the diagostics the device is not showing up on either gateway or TTN

Can i get the HAL and STM32WL libraries to try out for this

[STTwo-32]

Yes, to program the STM32WL MCUs, you can use the STM32CubeWL.

Best Regards.

Can it be used for this use case without nucleo board and which file to import

[STTwo-32]

I don't know how to program the module. But for the MCU, I suggest you use CubeMX, create a new project based on the MCU integrated on the Module. Creating a project will automatically use the STM32CubeWL and you can program directly your MCU. 

Best Regards.
