Download And Flash Releases

MeshCoreTel-firmware release assets are published on:

• https://github.com/VBart/MeshCoreTel-firmware/releases

There are currently two release tracks in this repo:

• companion-wifi
• repeater-mqtt

Pick The Right Asset

Download the asset that matches your board and firmware type.

Examples:

• heltec_v4_companion_radio_wifi-v1.14.1-abcdef.bin
• heltec_v4_repeater_mqtt-v1.14.1-vbart-meshcoretel-v1.0.1-abcdef.bin
• heltec_v4_repeater_mqtt-v1.14.1-vbart-meshcoretel-v1.0.1-abcdef-merged.bin

The important part is the board/env prefix:

• *_companion_radio_wifi
• *_repeater_mqtt

Which File To Flash

Use the standard .bin file when you are updating an existing device with the same target and partition layout.

Use the -merged.bin file when you want a clean install after erasing flash. This is the full ESP32 image and is intended to be flashed from address 0x0.

Practical rule:

• .bin = incremental update
• -merged.bin = erase and clean flash

Flashing Flow

1. Open the release page and download the file for your board.
2. Confirm the board name in the filename matches your hardware.
3. Choose one of the following: update existing firmware with the normal .bin, or erase the device first and flash the -merged.bin.
4. Reboot the device and complete any post-flash setup such as WiFi, MQTT, or radio settings.

Recommended Flasher

The recommended flasher is:

• https://meshcoretel.ru/ru/flasher

It includes native support for:

• companion_radio_wifi firmware
• repeater_mqtt firmware
• custom firmware files

Recommended usage:

• use the normal .bin there when you are updating an existing device
• use the -merged.bin there after an erase when you want a clean flash

Beginner Setup

If this is your first time flashing MeshCoreTel-firmware, the easiest path is:

1. Open https://meshcoretel.ru/ru/flasher.
2. Select the firmware type you want: Companion WiFi, Repeater MQTT, or Custom.
3. Flash the correct firmware for your board.
4. Use the built-in setup tools in the flasher site to finish first-time configuration.

The flasher site includes two especially useful actions after flashing:

• Repeater Setup
• Console

Repeater Setup

Repeater Setup is the guided first-time repeater flow.

It is the traditional way to configure a repeater after flashing, including:

• device name
• latitude and longitude
• admin and guest passwords
• radio settings, including preset selection
• advert interval
• flood advert interval
• flood max
• some advanced repeater settings

As of v1.2.1, the local repeater web panel also includes the same common repeater settings, so users can complete initial setup there and return for occasional troubleshooting or configuration changes. On MQTT repeaters that need maximum headroom, it is still best to disable the panel again when you are finished.

Console

Console is the raw CLI interface.

It is especially useful, and often required, for the initial Wi-Fi setup on both firmware tracks:

• set wifi.ssid <your-ssid>
• set wifi.pwd <your-password>

This applies to:

• companion_radio_wifi
• repeater_mqtt

Repeater MQTT Notes

repeater_mqtt builds include the MeshCoreTel-firmware MQTT additions. Depending on the board, they may also include the local web panel.

Typical first steps after flashing:

• set wifi.ssid
• set wifi.pwd
• set mqtt.iata
• confirm get mqtt.status
• optionally set mqtt.owner and mqtt.email
• optionally enable letsmesh-eu or letsmesh-us

Companion WiFi Notes

companion_radio_wifi builds are for companion devices that expose the app interface over WiFi instead of BLE or USB.

Typical first steps after flashing:

• set WiFi credentials
• confirm get wifi.status
• connect your client app to the companion over WiFi
