I bought your products, lora and lorawan end node.
when I look up the given library about lora,
i couldn't find the Channel Activity Detection function (CAD).

I knew that sx1272 can do CAD, however, your library seems not support that.

Am i right? if not, let me know how can i do CAD in libelium sx1272 module.

Hi oyj0594,

Yes, our library doesn't support it. We tested it and it doesn't work correctly because the module lost some packages using it and we didn't implemented this function.

Regards

Hi, and i have one more question.
do you implement all features of LoRaWAN 1.0.2 ?
there are lots of mac command defined by spec and mechanism such as ADR.

and i think there is no random channel selection mechanism in your library, however, spec says end node transmit data packet through a random channel each time.

Hi oyj0594,

All these features are are controlled by the module, not by the library. If your module is with the last firmware, the module will have all features of LoRaWAN 1.0.2 .

No, I don't think so..

in your lorawan implementation code, arduPiLoRaWAN, there is no specific functions about lorawan specification..

if your software is fine, where is the part of implementing MAC COMMAND (linkadrans, linkcheckans, etc..) ?

Hi oyj0594,

This module hasn't got specific functions for that, you can check the specifications of the Microchip module.
