Introduction

This tutorial covers the main features of Collect-view Protocol (CTP) available on ContikiOS 2.7. There are many different section of CTP codes that are distributed over different folders. In this tutorial we will cover the codes and their interdependence in brief details.

You will learn

Through this tutorial you will learn about different code components of CTP. This will help you in any projects that require deep understanding of the code or need modification of some portion of the code.

Description

void collect_open(struct collect_conn *c, uint16_t channels, uint8_t is_router, const struct collect_callbacks *callbacks);

This function opens a unicast channel in each node with the channel being (channels+1).

                  unicast_open(&tc->unicast_conn, channels + 1, &unicast_callbacks);
