Wow, I wouldn't say bad. There is a complete POSIX sockets example in the source code: https://github.com/RIOT-OS/RIOT/tree/master/examples/posix_sockets RIOT OS support the POSIX socket API. There are tons of examples in the Internet for POSIX sockets. But if you want to have a more complete code an guide. 1. Server on the sensor. UDP + Protobuf: https://github.com/Citrullin/RIOT/tree/ble_sensor_node/examples/env_sensor_network 2. Complete guide for this sensor server and the host application. (BLE, nrf52): https://github.com/Citrullin/documentation/blob/env_sensor_network/blueprints/0.1/environment-sensor/run-a-environment-sensor-and-client.md
