Flashing
From a browser (Chrome or Edge, no tools): open ESPHome Web, connect the board, choose Install, tick Erase device, and pick the .factory.bin. When it offers to set up Wi-Fi afterwards, skip it: these images are provisioned over Bluetooth.
With esptool:
esptool --chip <chip> erase-flash
esptool --chip <chip> write-flash 0x0 <image>.factory.binThe QT Py ESP32-S3 and ESP32-C6 need --before usb-reset; each bundle's README.txt has the exact commands, and scripts/flash.sh <bundle-dir> flashes a bundle from a checkout.
Then provision it: standalone images with Improv Wi-Fi, tedge-* images with lab-ztp-provisioner. See Provisioning Wi-Fi over BLE, including its security notes.
Updating over the air (tedge images)
Put the application images into your tenant's firmware repository, then install from the device's Firmware tab:
scripts/release/c8y-upload.sh v0.7.0Each image reports a firmware name unique to its device and app, and the version 0.7.0; c8y-firmware.json lists them.
tedge-zephyr 0.0.2. Features per image:

Measurements are published on te/device/<id>///m/<type> over the Cumulocity MQTT Service and need a Smart Function in the tenant; Telemetry in Cumulocity lists each app's topic, payload and units.
Signing
- Signed with MCUboot's public development key (root-ec-p256.pem): anyone can sign an image these bootloaders accept. Not for production devices.
A device's bootloader only accepts images signed with its own key: a device flashed from one key cannot be updated over the air to images signed with another.
