US 2025/0053403 A1 · FIRMWARE UPLOAD USING BLE CONNECTION TO BLUETOOTH MESH FIRMWARE DISTRIBUTOR NODE

Abstract

A system and method for uploading a new firmware image to a distributor node is disclosed. The distributor node is part of a Bluetooth mesh network. In some embodiments, one of the initiator node or the distributor node includes a GATT database. The GATT client (which may be the distributor node or the initiator node) connects with the GATT database and BLE messages are used to transmit the firmware image. These BLE messages do not have the constraints that are imposed on mesh messages, and therefore the upload occurs much more quickly. This technique is compliant with the Upload Firmware Out of Band (OOB) procedure defined in the Bluetooth Mesh specification. In another embodiment, the firmware image is transmitted from the initiator node to the distributor node using a L2CAP channel.

Dependent claims

A method of uploading a new firmware image to one or more network devices in a Bluetooth mesh network, comprising:

transmitting from an initiator node a standard Bluetooth Mesh packet, referred to as a Mesh Firmware Distribution Upload OOB Start PDU, which indicates an out of band firmware upload is being commenced;
uploading the new firmware image from the initiator node to a distributor node, wherein the new firmware image is transferred using BLE protocol data units (PDUS);
transmitting from the initiator node a standard Bluetooth Mesh packet, referred to as a Mesh Firmware Distribution Upload Get PDU, to obtain status of the firmware upload;
and
using the distributor node to transmit the new firmware image to the one or more network devices using standard Bluetooth Mesh PDUs.
