Notes

• debug mode DEBUG=miflora ts-node examples/basic.ts

• if you having trouble running the script on raspberry pi, run sudo setcap cap_net_raw+eip $(eval readlink -f `which node`). This grants the node binary cap_net_raw privileges, so it can start/stop BLE advertising without sudo. source

• use it with strict mode ts-node --use_strict examples/basic.ts

• if your flora's firmware version is older than 2.8.6, please install v0.1.0
