Debug output showing wrong RX frequencies

[Andrew Lindsay]

I’m using a NA915 part with a EU868 gateway as this is on a board a client has sent for testing. I am using the latest 3.0 library:
mbed-os: 5.4.7
libxDot version: 3.0.0-mbed144

I have set the EU868 channel plan but notice the RX1 frequency is in the correct band but the RX2 frequency is not. As a result I’m getting join failures but do see the join request on the gateway and LoRaWAN server. Eventually the node connects and is able to send data.

Debug output below:

Is this a bug in the library?

thanks
