LoRaPHY project, based upon SX1276Lib, hardware with NUCLEO-F103EB/L053R8 and other boards as well as multiple Radio modules of SX1272/1276/1278. The code contains MACRO definitions and can be configured as TX/RX only, PINGPONG and consider to be a code base of RTTY.

MAC Layer¶
LoRaWAN defines its MAC layer design for competitive uplink and time window for downlink. That is suitable for most of IoT DAQ systems. However, in some self-orgnized no-central-no-router network, competitive MAC layer is good enough. Therefore modified ALOHA algorithm is used, with RTS/CTS and time parameters.
DLL Layer¶
MLSE & MIB¶
LoRaWAN is well defined with MLSE and MIB.
X.25/AX.25¶
X.25 is a legacy protocol defined by CCITT/ITU. And AX.25 is a HAM version of X.25. Since AX.25 is still popular in HAM group, we are surveying the possibilities of put X.25 over LoRa MAC/DLL. It is just an option.
IPv6 over LoRa¶
IETF has a proposal of IPv6 over LoRa network.
