Questions tagged [protocols]

For questions about choosing a fitting or identifying a used protocol in IoT applications and systems. If you do know the specific protocol use a more specific tag. Please add specific protocol tags if you are choosing between specific protocols.

Use this tag for questions that are about choosing a fitting or identifying a used protocol in IoT applications and systems.

Consider the question check list if your question fits the tag. You can also look at the example questions. If this tag doesn't fit your question have a look below at somehow related tags that might fit your question better.

Question checklist

  • Is the question either about choosing a fitting protocol for an IoT application?
  • Or is the question about identifying a protocol that an IoT device uses?
  • Is choosing or identifying a protocol the core of your question?

Example questions

Not what you are looking for?

  • Use for questions about setting up and configuring networks for your IoT devices in general.
  • Add or use instead tags for specific protocols if you do know them, e.g. , or .

Do all Internet connected Things use the same "Application - TCP - IP - Hardware" stack to communicate?

I am not particularly internet savvy, and IoT technologies are especially confusing for me. I was reading this Stanford white paper on internet structure. In Diagram 2, it shows a representation of the software "stack" that a computer (PC) would use…

Can I implement ZigBee with generic hardware?

As I understand ZigBee is only a specification of a data transfer protocol. So I was expecting to find some library that implements this protocol to use it with my MCU and RF transceiver. Instead, I only have found specific ZigBee devices (e.g.…

Protocol for configuring IoT device settings

MQTT is widely used in IoT when it comes to exchanging application data between the end device and the host service. The publish-subscribe model makes it easy to use: no handshaking, negotiating etc (at least above the MQTT protocol layer). It's…

Does CoAP depend on IEEE 802.15.4?

In the CoAP specification, it is implied that IEEE 802.15.4 can be used in conjunction with CoAP. Is this a requirement or can CoAP also be used with other OSI layer 1, 2 protocols such as IEEE 802.11, BLE or LTE/5G/etc?
