The Breakout SDK for Massive IoT enables developers to exchange data between low-powered devices and their services running in the cloud. The SDK abstracts complex elements of Narrowband IoT (NB-IoT) deployment and removes development barriers by handling tasks such as network registration on your behalf.
The SDK is built to be cross-platform. It currently supports three modems: the u-blox SARA-R410 and SARA-N410 and the Quectel BG96. The SDK supports sending data over TCP and UDP, and using the modems’ internal MQTT and TLS implementations.
First, a few platform-specific functions need to be implemented as is described in the porting section of the Read Me. After that you can write the code in either blocking or non-blocking style (see the example).
If you are working in multithreaded environment, please note that that the Breakout SDK is not thread-safe, so it should either be owned by a single thread, or protected by a mutex.
