Modern microcontroller for embedded firmware, field testing and rapid prototyping.
Open source · MQTT · 1NCE
Open IoT playground with ESP32-S3, Adrastea-I and 1NCE.
ESPnarrow helps developers quickly build and test complete IoT systems: an open-source embedded library, a public test MQTT broker, temporary client certificates and a Node-RED web dashboard.
Compact cellular modem for narrowband IoT and LTE-M connectivity.
Cellular connectivity designed for IoT test and deployment scenarios.
Generate a temporary MQTT certificate
Devices connect to the broker through mTLS. The generated certificate is limited to a maximum of 30 days and the private key is never displayed on the page: it is provided only inside a downloadable archive.
How to test in 3 steps
1
Generate a certificate
Create certificates for your device with a unique Device ID (IMEI is recommanded).
2
Flash and configure
Use DeviceManagementDashboard from GitLab repo example.
3
Visualize
Track the device state and data usage in devices dashboard.
