Thingy:91 X: Hello nRF Cloud firmware
The Hello nRF Cloud firmware is the official, factory-programmed firmware for the nRF9151 SiP on the Thingy:91 X device. The latest release of the firmware is available for download from Thingy:91 X firmware releases, where you can also find the factory-programmed Connectivity Bridge for the nRF5340 SoC on the device.
The application searches for and connects to an LTE network and sends network and sensor data to nRF Cloud, using CoAP over UDP as the transport protocol. Sampled data that is sent from the application can be viewed in the hello.nrfcloud.com web interface.
Some of the key features of the firmware include:
LTE network connection management
Secure and efficient communication with nRF Cloud using CoAP with DTLS connection ID over UDP
Sensor data collection and transmission
Firmware-Over-the-Air (FOTA) capability for application and modem updates
Modem tracing capability
LED indication for visualizing the operating state of the application
The project repository is based on the NCS Example Application and customized to the needs of the application. Read more about the various aspects of the firmware in the following sections.
