About some of the problems for LMiC on Arduino board #48

Open hongi200 opened 7 years ago

hongi200 commented 7 years ago

I've read that you write Arduino-LMiC library and porting it. So,have some questions for you.

This is my hardware. (Arduino UNO, LoRa module: SX1272, Multiprotocol Radio Shield for Arduino) link: https://www.cooking-hacks.com/documentation/tutorials/extreme-range-lora-sx1272-module-shield-arduino-raspberry-pi-intel-galileo/

Can I do these works? And how

Sending packets uplink, taking into account duty cycling. Encryption and message integrity checking. Receiving downlink packets in the RX2 window. Custom frequencies and datarate settings. Over-the-air activation (OTAA / joining)

That's PHY layer or MAC layer ?

I hope to get your suggestions because I'm going to talk about this aspect of these problem with my professor in next week.

Thank you for read

regard.

If you selected the right radio chip (SX1272 instead of SX1276) in config.h,try to see the issue #9: the official Arduino Uno board I have can not handle 10 MHz SPI clock. Try to modify this line to set the SPI speed to 2 MHz
