BleConstants

Meshtastic BLE GATT layout per docs/protocol.md §3.

The Meshtastic mesh service exposes four characteristics on the same primary service. The service UUID is also used by the host as a scan filter to discover Meshtastic radios.

Properties

FROMNUM

val FROMNUM: Characteristic

Lazily resolved fromnum characteristic (used for notifications).

FROMNUM_UUID

val FROMNUM_UUID: Uuid

fromnum — NOTIFY+READ characteristic. A 4-byte little-endian counter that the device increments whenever it pushes data into the fromradio queue.

FROMRADIO

val FROMRADIO: Characteristic

Lazily resolved fromradio characteristic (used for reads).

FROMRADIO_UUID

val FROMRADIO_UUID: Uuid

fromradio — READ characteristic. Each read returns one full FromRadio protobuf payload, or an empty buffer once the device's outbound queue is drained.

MESH_SERVICE_UUID

val MESH_SERVICE_UUID: Uuid

Primary GATT service exposed by every Meshtastic radio.

TORADIO

val TORADIO: Characteristic

Lazily resolved toradio characteristic (used for writes).

TORADIO_UUID

val TORADIO_UUID: Uuid

toradio — WRITE-WITHOUT-RESPONSE characteristic. Each write carries one full ToRadio protobuf payload (no 0x94 0xC3 framing — BLE uses GATT message boundaries directly).
