A packet forwarder to enable bi-directional communication based on SX1276/72 LoRa Transceiver

Hi Guys,
firstly, I will like to appreciate the support you are offering mostly to us computer science student and to those who want to try new IoT related technical stuff.
I have a question or rather a groups of subjects. Before going into my questions, let me give you guys the background of my issues.

I was required, in the context of my thesis, to create a bi-directional communication over the LoRa modulation. The interface is between two “smart devices” consisting of a Raspberry Pi 3 and a LoRa /GPS HAT based on the SX1276 LoRa Transceiver. Both devices will act as Server and Client interchangeability. On both devices will run a packet forwarder the enables them forward data to a local TCP server for further processing.
Presently, both devices can send and receive data from/to each other using the RPI-transceiver software as described in (https://github.com/dragino/rpi-lora-tranceiver). I found a packet forwarder software at (https://github.com/kersing/packet_forwarder), this, however, is not designed for the Lora Transceiver x1276/SX1272 but for the concentrator based on SX1301, which is a multi-channel full gateway devices. It is evident that the software does suit my use case ( in my opinion). I will like someone to either point me to a source of software that could help me achieve the goals described earlier or give me some tips in modifying ( adapting) the existing software to my need. Thank in advance.
