Issue: Error on downlink

I am running the example on both the xDot DK and the B-L072Z-LRWAN1 LoRa®Discovery kit.

I am connecting successfully to The Things Network and can upload data without issue. However when I try to send a downlink message I get the indication but the callback shows an error that indicates it has not received anything. I see the following in the output when connected to the dev boards:

Quote:

Dummy Sensor Value = 4.3 [INFO][LSTK]: RTS = 25 bytes, PEND = 0 [DBG ][LMAC]: Next Channel Idx=5, DR=5 [DBG ][LSTK]: Frame scheduled to TX..

25 bytes scheduled for transmission

Received message from Network Server nothing to read

receive() - Error code -1001 [DBG ][LSTK]: Ack received.

Message Sent to Network Server

I have tried this many times and always the same issue. This is using the latest revision at this time, Revision 46fe769 in the online IDE.

Thanks

Andrew
