Hi,
I am using Discovery kit (B-L072Z-LRWAN1 - STM32L0 Discovery kit LoRa, Sigfox, low-power wireless - STMicroelectronics) as an end node. I am making use of AT Slave commands (V2.1.0 / 10-Aug-2021) of this(I-CUBE-LRWAN - LoRaWAN software expansion for STM32Cube (UM2073) - STMicroelectronics) package.
As per release notes , this package is LoRaWAN® version V1.0.3 March 2018 compliant.
End node is class A device , region set to EU868 band.
I am unable to join the network using OTAA mode.
I get the following error on my serial COM port of end node:
10/25/2021 18:54:06 [TX] - AT+JOIN=1<CR>

I am using STM gateway (https://www.thethingsnetwork.org/docs/gateways/st/) configured to send payload to eu1.cloud.thethings.network.
It will be a great help if anyone can help with probable cause for the same and pointers resulting network join failure.
.
Thanks in advance.
