Handle zero-length downlink in Arduino_LoRaWAN::NetRxComplete #50

Closed terrillmoore closed 5 years ago

terrillmoore commented 5 years ago

When reviewing arduino-lmic docs, discovered that the proper form for checking for RX is:

if (LMIC.dataLen != 0 || LMIC.dataBeg != 0)

Right now we only have

if (LMIC.dataLen != 0)

which means that zero-length downlinks are not indicated to the client.

Labeled as a bug because I didn't intend to suppress zero-length downlinks.
