No downlink received with WaziHat and LMIC

[cdupont]

I don't get the downlink sent by WaziHat. WaziHat seems to send it:

In this log, I can see a packet beeing received by WaziHat, then it sees that there is a downlink packet queued and sends it. However, it is not received by WaziDev (LMIC):

16721219: EV_TXCOMPLETE (includes waiting for RX windows)
Packet queued

This works with other concentrators.

The reception happens at 56:07.838, and the transmission at 56:08.840 and lasts nearly 2 seconds. @j-forster is it OK?

Downlink works with non-LMIC library, though. LMIC timings might be too precise...

closing as obsolete (we don't use LMIC anymore)
