Mass provision devices using AWS IoT involves creating a fleet provisioning template and using AWS IoT Device Management service.

• Create a fleet provisioning template in AWS IoT console

• Use the template to provision multiple devices at once

• Utilize AWS IoT Device Management service for managing and monitoring provisioned devices

Azure IoT provides various methods for provisioning devices including manual, automatic, and zero-touch provisioning.

• Use Azure IoT Hub Device Provisioning Service for automatic provisioning

• Leverage Azure IoT Hub Device Twins for manual provisioning

• Implement zero-touch provisioning using Azure IoT Edge

I have worked on protocols such as MQTT, CoAP, HTTP, and LoRaWAN in IoT projects.

• MQTT (Message Queuing Telemetry Transport)

• CoAP (Constrained Application Protocol)

• HTTP (Hypertext Transfer Protocol)

• LoRaWAN (Long Range Wide Area Network)

I2C is a serial communication protocol used to connect multiple devices in a master-slave configuration.

• I2C uses two wires - SDA (data line) and SCL (clock line) for communication

• Devices are connected in a bus topology with a master device controlling the communication

• Each device on the bus has a unique address for identification

• Communication is initiated by the master device which sends start and stop signals

• Data is t...read more

The master with the lower address will take preference in sending data on I2C.

• The master with the lower address on the I2C bus will take preference in sending data.

• I2C arbitration is based on the address of the master, with lower addresses having higher priority.

• If two masters attempt to send data simultaneously, the one with the lower address will win the arbitration and proceed to send its data.
