# Basic Fuota

{% hint style="info" %}
It should be noted that FUOTA will not be supported to all end users, YOBIIQ will select Network Service Providers on which the FUOTA functionality will be tested.

They will be listed under the Verified Network Service Providers section.
{% endhint %}

## Basic Fuota

Starting in the V2.0.0 release of the iQ LoRaWAN Stack we will provide a basic fuota functionality.

The basic fuota functionality is based on;

* [LoRaWAN Remote Multicast Setup Specification v2.0.0 (TS005).](https://resources.lora-alliance.org/technical-specifications/ts005-2-0-0-remote-multicast-setup)
* [LoRaWAN Fragmented Data Block Transport Specification v2.0.0 (TS004).](https://resources.lora-alliance.org/technical-specifications/ts004-2-0-0-fragmented-data-block-transport)
* [LoRaWAN Application Layer Clock Synchronization Specification v2.0.0 (TS003).](https://resources.lora-alliance.org/technical-specifications/ts003-2-0-0-application-layer-clock-synchronization)

Within the basic fuota functionality there are a few steps that are taken (behind the scenes);

1. Synchronize the device clock `AppTimeReq & AppTimeAns` 
2. Setup a multicase group using `McGroupSetupReq & McGroupSetupAns` 
3. Setup a class C session using `McClassCsessionReq & McClassCsessionAns` 
4. Setup a fragmentation session via `FragSessionSetupReq & FragSessionSetupAns` 
5. Transfer the fragmented data and perform a CRC32 check to confirm data integrity
6. Test the bootloader and load the new firmware.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.yobiiq.com/welcome/lorawan-stack/firmware-updates-over-the-air-fuota/basic-fuota.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
