I-CUBE-LRWAN v2.0.0 AT Slave with B-L072Z-LRWAN1 not receiving join response
I am having trouble receiving the join response when attempting to join the local LoRaWAN network in NZ (AS923) using the B-L072Z-LRWAN1 evaluation board with the type ABZ module from Murata. It is running the I-CUBE-LRWAN v2.0.0 AT Slave firmware.
I can see the join request reach the network and I can see it send the response however, the evaluation board does not seem to receive the response. It takes several join attempts for the device to eventually receive the response and join. I have tried loading previous versions of the AT Slave firmware based on I-CUBE-LRWAN v1.2.2 and the device has no problem joining. I assume that the new firmware has changed something with regards to the receiver sensitivity but not sure what.
Has anyone encountered this issue and if so how do you fix it?
