ThingSet Zephyr SDK

This repository contains a software development kit (SDK) based on Zephyr RTOS to integrate communication interfaces using the ThingSet protocol into an application with minimum effort.

Testing with native_posix board

west build -b native_posix samples/counter -t run

Testing with LoRaWAN

west build -b olimex_lora_stm32wl_devkit samples/counter -- -DEXTRA_CONF_FILE=lorawan.conf

Testing with CAN bus

west build -b native_posix samples/counter -t run -- -DEXTRA_CONF_FILE=can.conf

Testing WebSocket with native_posix

Start net-setup from Zephyr net-tools to create zeth interface:

sudo ../tools/net-tools/net-setup.sh

Forward packets from the the zeth interface to the internet via wifi/ethernet interface (replace wifi0 with the actual interface name):

sudo sysctl net.ipv4.ip_forward=1
sudo iptables -t nat -A POSTROUTING -o wifi0 -j MASQUERADE
sudo iptables -A FORWARD -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
sudo iptables -A FORWARD -i zeth -o wifi0 -j ACCEPT

Afterwards run the nativ_posix board with websocket support from another shell:

west build -b native_posix samples/counter -- -DEXTRA_CONF_FILE="native_websocket.conf storage_flash.conf"
./build/zephyr/zephyr.exe -flash=samples/counter/virtual-flash.bin

The virtual-flash.bin file is used to store custom data like server hostnames and credentials.

Update server details via ThingSet:

picocom /dev/pts/123            # replace 123 with printed number
select thingset
=Networking {\"sWebsocketHost\":\"your-server.com\",\"sWebsocketPort\":443,\"sWebsocketAuthToken\":\"your-token\"}

Check socket connections
