Firmware Update Guide

reSpeaker Clip supports two firmware update methods that do not require a debug probe:

1. Bluetooth OTA: Send the firmware package to the device through BLE. This is suitable for daily updates.
2. Recovery mode flashing: Put the device into USB serial recovery mode and transfer the firmware package through a USB serial port.

Both methods use MCUboot's mcumgr Simple Management Protocol (SMP). Bluetooth OTA uses BLE transport, while Recovery mode flashing uses USB CDC-ACM serial transport. reSpeaker Clip does not use native USB DFU flows such as dfu-util.

Firmware File Types

Firmware releases may include the following files:

File Type	Description	Usage
clip-<version>-*-single.*	Single application partition update package, suitable for updating only the Clip SDK / app partition	USB serial DFU
clip-<version>-*-signed.bin	Signed application firmware image	USB serial DFU, BLE OTA
clip-<version>-*-ota.zip	Multi-image update package, usually including app and network core	USB serial DFU, BLE OTA
clip-<version>-*-merged.hex	Full image including MCUboot, app, and network core	Requires a debugger such as J-Link
clip-<version>-*-merged_CPUNET.hex	Network core image only	Requires a debugger such as J-Link

For regular Bluetooth OTA updates, use -ota.zip first. For developer flashing through Recovery mode, prefer firmware packages with the single suffix. Typical Clip SDK changes only affect the application partition and do not require updating the network core. -merged.hex and -merged_CPUNET.hex are mainly used for development, production, or debugger-based flashing.

Method 1: Bluetooth OTA

Bluetooth OTA is suitable when the device can boot normally and can be discovered by a phone through BLE. It is recommended to use the mobile nRF Connect app for OTA. The BLE tool in nRF Connect for Desktop usually requires an additional Nordic BLE adapter.

Basic workflow:

1. Prepare the clip-<version>-*-ota.zip firmware package.
2. Send the firmware package to your phone.
3. Open nRF Connect on your phone.
4. Search for and connect to reSpeaker Clip through BLE.
5. After connection, confirm that SMP Service is visible.
6. Tap the DFU icon in the upper-right corner and select the -ota.zip or -signed.bin firmware package.

7. Keep the default Test and Confirm mode and tap OK to start the update.

8. Wait for transfer, verification, and automatic device reboot to complete.
9. Reconnect to the device and check the firmware version.

tip

During OTA, keep the phone close to the device, do not send nRF Connect to the background, and make sure the device is not connected to the SenseCraft Voice App at the same time.

Method 2: Recovery Mode Flashing

Recovery mode is a developer-oriented USB flashing mode. It transfers firmware through a USB CDC-ACM serial port using the MCUboot / mcumgr SMP protocol. It is recommended to use the nrfutil mcu-manager command line workflow.

Enter Recovery Mode

Recovery mode provides flashing capability through MCUboot USB serial recovery. To enter it:

1. Confirm that the USB cable supports data transfer.
2. Plug the USB cable into the charging base.
3. Place reSpeaker Clip onto the charging base and gently twist the device so that the charging contacts are firmly connected.
4. After the screen shows the USB / charging icon, press and hold the Action Button until the screen shows Recovery Mode.
5. When Recovery Mode is displayed, the device has successfully entered USB serial recovery mode and should enumerate as a serial port:
   • Windows: COMx
   • macOS: /dev/cu.usbmodem*
   • Linux: /dev/ttyACM0

On Windows, the device may enumerate multiple virtual serial ports, for example:

Product         reSpeaker Clip DFU
Ports           COM10, vcom: 0
                COM11, vcom: 1
Traits          serialPorts, usb

For flashing, try the serial port corresponding to vcom: 1 first, such as COM11 in the example above. If connection or upload fails, try the other serial port.

note

Recovery mode requires USB/VBUS detection. Before entering this mode, make sure the charging base contacts are firmly connected. If the screen does not show a USB / charging icon, the device may be physically placed on the base but not actually connected to USB.

Flash with nrfutil mcu-manager

nrfutil is Nordic's command line tool. Use version 8.x or later and install the mcu-manager plugin.

Newer versions of nrfutil use a subcommand plugin mechanism. For first-time use, install the device and mcu-manager subcommands:

nrfutil install device
nrfutil install mcu-manager

If nrfutil device list reports nrfutil command device not found, the device subcommand has not been installed. Run nrfutil install device first.

List current serial devices:

nrfutil device list

Upload the application partition firmware. Prefer the firmware package with the single suffix:

nrfutil mcu-manager serial image-upload \
    --firmware clip-<version>-production-single.zip \
    --serial-port COMx

If the release package provides a signed application image, you can also upload -signed.bin:

nrfutil mcu-manager serial image-upload \
    --firmware clip-<version>-production-signed.bin \
    --serial-port COMx

For a full app + network core update, upload -ota.zip:

nrfutil mcu-manager serial image-upload \
    --firmware clip-<version>-production-ota.zip \
    --serial-port COMx

After upload, reset the device to apply the new firmware:

nrfutil mcu-manager serial reset --serial-port COMx

Replace COMx with the actual serial port shown in Windows Device Manager or nrfutil device list. If the device shows multiple vcom ports, try the port corresponding to vcom: 1 first. If connection or upload fails, switch to the other port and try again. On macOS / Linux, use /dev/cu.usbmodem* or /dev/ttyACM0.

tip

If the flashing progress stays at 100% and the tool does not exit automatically, do not repeatedly unplug and replug the device. Run:

nrfutil mcu-manager serial reset --serial-port COMx

Then check the firmware version after the device restarts.

More Firmware Update Methods

For debugger-based flashing or more Recovery mode troubleshooting methods, refer to the reSpeaker Clip Advanced Firmware Update Guide (coming soon).

Development Guide

For developer and enterprise integration scenarios, reSpeaker Clip can be extended through the firmware SDK, application SDK, and communication protocols.

Firmware SDK

The reSpeaker Clip firmware is built on nRF Connect SDK / Zephyr RTOS and runs on the nRF5340 + nRF7002 platform. It is not a single driver example, but a device-side framework organized around audio capture, state machine, BLE / Wi-Fi communication, file management, firmware update, and low-power management.

Firmware system architecture:

From a development perspective, the firmware is mainly divided into the following layers:

• Application Layer: Handles event dispatching, AT Server, button processing, and user interaction states.
• Service Layer: Handles BLE / UDP transport abstraction, file transfer, configuration management, and NVS storage.
• Processing Layer: Handles audio capture, SpeexDSP noise reduction / dynamic range processing, and Opus encoding.
• Hardware Abstraction Layer: Encapsulates PDM microphone, SD FAT32, BLE, Wi-Fi, PMIC, and other hardware capabilities.
• Zephyr RTOS Kernel: Provides kernel primitives such as k_msgq, k_sem, k_mutex, k_thread, and k_mem_slab.

A typical development workflow is: set up the Zephyr / nRF Connect SDK environment, obtain the reSpeaker Clip firmware project, confirm the board target and configuration files, build and flash the firmware, check serial logs, and finally verify recording, file sync, and firmware update through the SenseCraft Voice App or BLE / Wi-Fi protocols.

For more firmware architecture, environment setup, build, flashing, and secondary development details, refer to the reSpeaker Clip Firmware Development Guide (coming soon).
