{% 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.

## 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.
