Dragino lora shield + arduino + 3 sensors works fine but there is some warnings

Please help if you have the same problem.

The warnings are down below

These warnings are harmless, but should probably be fixed at some point. They might be fixed already in LMIC 1.6, or the https://github.com/lorabasics/basicmac stack based on LMIC, so just ignore them here for now. I'll leave this issue open in case anyone else wonders.

@matthijskooijman please where can i find the latest updated LMIC library ? Thank you.

[matthijskooijman]

I can't help you with that, I haven't ported the updated 1.6 library yet (though I have had plans for years). I think there are some forks of this repo around that do have the newer version. I did look into basicmac at some point, but haven't managed to make that work on Arduino yet (also, it seems to have grown too big for AVR).

It would be more effective to build an Arduino port of the current Semtech base code that will soon be LoRaWan 1.1 compliant... it's an up to date derivative of the IBM LMiC 1.6 codebase... will also feature firmware updates over LoRaWan

@trlafleur, AFAIU LoRaMac-node is not related to LMIC in any way, it's a completely separate codebase.

BasicMac (as I linked above) OTOH, is based on LMIC and should (almost?) 1.1 compliant, but my first attempt at porting show that it's also a lot bigger than LMIC 1.5/1.6 (i.e. probably won't fit into a 328p).

[trlafleur]

its time for people to move on, 32bit processors like the M0, are cheaper, faster, less power that 8bit 328P... my two bits....

@matthijskooijman problem solved. You only have to cast it and the compilation will past with out any warning. LMIC_setSession (0x1, DEVADDR, (xref2u1_t)NWKSKEY, (xref2u1_t)APPSKEY);

[matthijskooijman]

Ok, thanks for reporting back. I'm closing this issue as solved :-)
