Radios & firmware

Compatibility starts
with the exact board.

The proposed NodeSwitch 0.9 closed beta focuses on two radio variants. Firmware coverage depends on the board, package version and firmware role.

Development snapshot · 14 November 2026

Firmware installation is not publicly available.

The current release preview disables installation, configuration restoration and full-flash restoration. Development tests do not establish public release support.

Radios in the proposed beta

STANDARD V4.3 ONLY

Heltec V4.3 OLED

Standard OLED board, ESP32-S3R2 and the exact supported 16 MiB flash configuration, subject to live hardware and security checks.

Verified package library and supported read-only USB checks.
Full-flash backup acquisition uses the slower read-only ROM path in the release preview.
V4.2, V4.3.1 and V4-R8 OLED/TFT are outside this beta scope.

TFT VARIANT ONLY

Heltec T114 TFT

The TFT display variant. USB family identification alone does not distinguish it from the no-display board; variant confirmation is required.

Supported Meshtastic configuration capture and application readback management.
Configuration and CURRENT.UF2 captures are not complete flash backups.
CURRENT.UF2 readback is not a supported restore image.

Firmware coverage in development

This table describes exact development evidence and catalogue limits. Every installation path below remains disabled in the current release build. It is not a list of publicly installable firmware.

NodeSwitch 0.9 preparation — version-specific development status
Firmware	Standard V4.3 OLED	T114 TFT
Meshtastic `2.7.26.54e0d8d`	Owner-tested debug installation and positive running identity.Release installation disabled.	Owner-tested debug application UF2 and configuration capture/restore.Release installation and restore disabled.
MeshCore `1.18.0`	USB and Bluetooth Companion roles have owner-reported debug switching evidence.USB silence cannot identify Bluetooth Companion.	USB Companion has physical switching and USB identity evidence.BLE Companion, Repeater and Room Server do not have separate physical qualification.
MeshCom `4.40a.11.07`	Owner-reported debug boot and switch back to Meshtastic.Release-path identity and recovery qualification remain.	Owner-tested debug switching and positive identity.Release installation disabled.
openHop Modem `1.4.0`	Owner-tested debug backup/install, device verification and running identity.	Owner-tested debug switching and positive identity.
MeshMesh	`0.30.3 / 0.32.0 / 0.33.0` No exact V4.3 physical completion recorded.Older versions depend on verified cache/import.	`0.30.3` Owner-tested debug switching and positive identity.Cache/import only; the old upstream download is unavailable.
RNode `1.86`	Owner-tested debug installation and provisioning; a later beta candidate.Not in the initial minimum release scope.	Excluded from proposed beta qualification.Official and experimental paths have unresolved startup/storage problems.

A verified download, a successful write and working radio operation are different evidence. Firmware availability and redistribution approval are also separate.

Before connecting

Use an Android phone with USB host/OTG support and a compatible USB data cable.
Connect one radio at a time and grant Android’s USB permission.
Confirm the physical model and revision; selecting a model does not prove its identity.
Keep an independently verified portable backup before changing firmware or phones.

Other Heltec revisions, T114 no-display, LILYGO and RAK boards are outside the proposed 0.9 beta scope. No delivery date is promised for additional hardware.
