OTA Update types and Points to consider

Over-The-Air (OTA) update allows the addition of new services to the existing devices. There are two types of OTA Updates - Connected and Mesh

Connected OTA can be further classified into two types: 

• Local OTA – wherein the OTA update will be done using the files stored in the device (i.e. Browse from the device)
• Cloud OTA – wherein the OTA update will be done using the files stored in the Cloud (i.e. Check for updates)

Points to consider while performing an OTA update

Connected OTA 

• OTA update takes a few minutes to complete – 1 minute for Nordic devices and 15 minutes for T-Link devices (approx.).
• The devices to be updated must be in ON state and shouldn’t be rebooted.
• When carrying out connected OTA Update, the light device must be in close proximity with the Bluetooth device (phone or tab).

Mesh OTA

All devices of a device type in a Zone can be updated in one go using the Mesh OTA update feature. Mesh OTA updates can be initiated from the Web UI.

•  Ensure to check the device reachability before initiating the Mesh OTA Update.
• It requires a Gateway connected to the cloud to be present in the Zone.
• In case the device is rebooted, the OTA update will be re-initiated automatically.
• The Mesh OTA takes approximately 3–4 hours to get completed.
• The Blue and Green LEDs in the Gateway will be steady throughout the OTA update and then move to Connected Mode, where the LEDs will flash every 1 second.

Note:

• The OTA Update can be done only for Controllers, Drivers, Sensors and AC-powered switches.
• The Gateways are automatically updated
