+# BLE Mesh Implementation Plan
+
+## Overview
+
+Add BLE as a mesh transport alongside LoRa, enabling Meshtastic nodes to relay packets over Bluetooth Low Energy. Follow the same handler pattern used by UDP multicast ([UdpMulticastHandler](src/mesh/udp/UdpMulticastHandler.h)) — a standalone handler class with `onSend()` hooked into `Router::send()` and received packets injected via `router->enqueueReceivedMessage()`. No changes to `RadioInterface` or Router architecture needed.
+
+BLE mesh is useful for:
+
+- Dense indoor deployments where LoRa range is excessive
+- Extending mesh reach through devices that lack LoRa hardware
+- Hybrid LoRa+BLE networks (gateway nodes bridge both transports)
+- Lower latency links between nearby nodes
+
+---
+
+## Architecture
+
+### Pattern: Same as UDP Multicast
+
+```
+                                    Router::send()
+                                        │
+                    ┌───────────────────┼───────────────────┐
+                    │                   │                   │
+                    ▼                   ▼                   ▼
+            iface->send(p)    udpHandler->onSend(p)   bleMeshHandler->onSend(p)
+               (LoRa)              (UDP)                (BLE mesh)
+
+                                Router::enqueueReceivedMessage()
+                                        ▲
+                    ┌───────────────────┼───────────────────┐
+                    │                   │                   │
+             LoRa RX ISR     udpHandler->onReceive()  bleMeshHandler->onReceive()
+```
+
+The existing UDP pattern ([Router.cpp:378-382](src/mesh/Router.cpp#L378-L382)):
+
+```cpp
+#if HAS_UDP_MULTICAST
+    if (udpHandler && config.network.enabled_protocols & ...) {
+        udpHandler->onSend(const_cast<meshtastic_MeshPacket *>(p));
+    }
+#endif
+```
+
+BLE mesh hooks in identically, right next to it.
+
+---
+
+## Phase 1: Protobuf & Configuration
+
+### 1.1 Transport mechanism enum
+
+**File:** protobufs repo (`mesh.proto`)
+
+Add a new transport type alongside the existing ones:
+
+```protobuf
+enum TransportMechanism {
+    // ... existing 0-7 ...
+    TRANSPORT_BLE_MESH = 8;
+}
+```
+
+### 1.2 BLE Mesh configuration
+
+Add BLE mesh config to the device config protobuf:
+
+```protobuf
+message BleMeshConfig {
+    bool enabled = 1;
+
+    // Operating mode
+    enum Mode {
+        OFF = 0;
+        ADVERTISE_AND_SCAN = 1;  // connectionless (extended adv)
+        GATT = 2;                // connection-based
+        HYBRID = 3;              // both
+    }
+    Mode mode = 2;
+
+    // Scan/advertising interval in ms (latency vs power tradeoff)
+    uint32_t interval_ms = 3;  // default: 500ms
+
+    // TX power level (platform-mapped)
+    int8_t tx_power = 4;  // dBm
+
+    // Max BLE mesh peers to track
+    uint32_t max_peers = 5;  // default: 8
+}
+```
+
+---
+
+## Phase 2: BLE Mesh Handler — Core Class
+
+### 2.1 Base handler (platform-agnostic)
+
+**New file:** `src/mesh/BLEMeshHandler.h`
+
+Follow the `UdpMulticastHandler` pattern — a simple class, not a `RadioInterface`:
+
+```cpp
+#pragma once
+#if HAS_BLE_MESH
+
+#include "configuration.h"
+#include "mesh/Router.h"
+
+class BLEMeshHandler {
+public:
+    BLEMeshHandler() : isRunning(false) {}
+
+    virtual void start() = 0;
+    virtual void stop() = 0;
+
+    // Called from Router::send() — broadcast packet over BLE
+    virtual bool onSend(const meshtastic_MeshPacket *mp) = 0;
+
+protected:
+    bool isRunning;
+
+    // Shared RX path: decode and enqueue into router
+    void deliverToRouter(const uint8_t *data, size_t len) {
+        meshtastic_MeshPacket mp;
+        if (!pb_decode_from_bytes(data, len, &meshtastic_MeshPacket_msg, &mp))
+            return;
+        if (mp.which_payload_variant != meshtastic_MeshPacket_encrypted_tag)
+            return;
+
+        mp.transport_mechanism =
+            meshtastic_MeshPacket_TransportMechanism_TRANSPORT_BLE_MESH;
+        mp.rx_snr = 0;
+        mp.rx_rssi = 0;
+
+        UniquePacketPoolPacket p = packetPool.allocUniqueCopy(mp);
+        if (router)
+            router->enqueueReceivedMessage(p.release());
+    }
+
+    // Shared TX path: encode packet to bytes
+    size_t encodeForBLE(const meshtastic_MeshPacket *mp, uint8_t *buf, size_t bufLen) {
+        return pb_encode_to_bytes(buf, bufLen, &meshtastic_MeshPacket_msg, mp);
+    }
+};
+
+#endif // HAS_BLE_MESH
+```
+
+### 2.2 Wire format
+
+Same as UDP multicast — protobuf-encoded `meshtastic_MeshPacket` (already encrypted). This means:
+
+- Packets are encoded with `pb_encode_to_bytes()` on TX
+- Decoded with `pb_decode_from_bytes()` on RX
+- Encryption already applied by Router before `onSend()` is called
+- Same deduplication via `PacketHistory` (keyed on `sender, id`)
+
+### 2.3 Echo prevention
+
+Same pattern as UDP ([UdpMulticastHandler.h:102](src/mesh/udp/UdpMulticastHandler.h#L102)):
+
+```cpp
+if (mp->transport_mechanism == meshtastic_MeshPacket_TransportMechanism_TRANSPORT_BLE_MESH) {
+    LOG_ERROR("Attempt to send BLE-sourced packet over BLE");
+    return false;
+}
+```
+
+---
+
+## Phase 3: ESP32 Implementation (NimBLE)
+
+### Platform: ESP32, ESP32-S3, ESP32-C3, ESP32-C6
+
+**New files:** `src/nimble/NimbleBLEMesh.h` / `NimbleBLEMesh.cpp`
+
+```cpp
+#pragma once
+#if HAS_BLE_MESH && defined(ARCH_ESP32)
+
+#include "mesh/BLEMeshHandler.h"
+#include "nimble/NimbleBluetooth.h"
+
+class NimbleBLEMesh : public BLEMeshHandler {
+public:
+    void start() override;
+    void stop() override;
+    bool onSend(const meshtastic_MeshPacket *mp) override;
+
+private:
+    // --- Advertising mode ---
+    void startScanning();
+    void stopScanning();
+    static void onScanResult(const ble_gap_disc_desc *desc, void *arg);
+    void broadcastViaAdv(const uint8_t *data, size_t len);
+
+    // --- GATT mode ---
+    void setupMeshService();
+    static int onMeshCharWrite(uint16_t conn_handle,
+                               const ble_gatt_error *error,
+                               ble_gatt_attr *attr, void *arg);
+    void sendViaGATT(const uint8_t *data, size_t len);
+
+    // --- Peer tracking ---
+    struct BLEPeer {
+        NodeNum nodeNum;
+        ble_addr_t addr;
+        int8_t rssi;
+        uint32_t lastSeenMs;
+        uint16_t connHandle;  // 0 if not connected
+    };
+    std::vector<BLEPeer> peers;
+    void updatePeer(const ble_addr_t &addr, NodeNum nodeNum, int8_t rssi);
+    void pruneStale();
+};
+
+#endif
+```
+
+### 3.1 Advertising mode (connectionless)
+
+Encode mesh packets into BLE extended advertisements with Meshtastic manufacturer data.
+
+**TX flow:**
+
+1. `onSend()` called from `Router::send()`
+2. Encode packet via `encodeForBLE()`
+3. Pack into extended advertisement manufacturer data
+4. Broadcast for configurable number of intervals
+
+**RX flow:**
+
+1. NimBLE scan callback fires
+2. Check manufacturer ID for Meshtastic magic
+3. Extract protobuf bytes
+4. Call `deliverToRouter()`
+
+**Advertisement structure:**
+
+```
+AD Type: 0xFF (Manufacturer Specific)
+Company ID: 0x????? (Meshtastic BLE SIG ID or 0xFFFF)
+Mesh Version: 1 byte
+Protobuf payload: variable (up to ~244 bytes with extended adv)
+```
+
+**Key NimBLE APIs:**
+
+- `ble_gap_ext_adv_set_data()` / `ble_gap_ext_adv_start()` — extended adv TX
+- `ble_gap_disc()` or `ble_gap_ext_disc()` — scanning
+- Scan callback receives `ble_gap_disc_desc` or `ble_gap_ext_disc_desc`
+
+### 3.2 GATT mode (connection-based)
+
+Add a new GATT service for mesh relay, separate from the phone API service:
+
+**New Mesh Relay Service:**
+
+```
+Mesh Relay Service UUID: (new, distinct from phone service in BluetoothCommon.h)
+├── MeshTX (WRITE_NO_RSP) — peers write mesh packets to us
+├── MeshRX (NOTIFY)       — we notify peers of new mesh packets
+└── MeshPeer (READ)       — our NodeNum for discovery
+```
+
+**TX:** Write to MeshTX on all connected peers (broadcast) or specific next-hop peer (directed).
+**RX:** MeshTX write callback → `deliverToRouter()`.
+
+### 3.3 Coexistence with phone BLE
+
+Both services registered on the same NimBLE host:
+
+- Phone API service: existing UUIDs ([BluetoothCommon.h](src/BluetoothCommon.h))
+- Mesh relay service: new UUIDs
+- Separate connection handles for phone vs mesh peers
+- Use extended adv set 0 for phone, set 1 for mesh (NimBLE supports multiple adv sets)
+- Reserve 1 connection for phone, remaining for mesh peers
+
+### 3.4 ESP32 variant considerations
+
+| Variant  | BLE | Extended Adv | Max Conn | Strategy                                |
+| -------- | --- | ------------ | -------- | --------------------------------------- |
+| ESP32    | 4.2 | No           | 9        | GATT-only (legacy adv too small at 31B) |
+| ESP32-S3 | 5.0 | Yes          | 9        | Full adv+GATT                           |
+| ESP32-C3 | 5.0 | Yes          | 3        | Adv preferred (limited connections)     |
+| ESP32-C6 | 5.0 | Yes          | 9        | Full adv+GATT                           |
+

+
+## Phase 4: nRF52 Implementation (SoftDevice/Bluefruit)
+
+### Platform: nRF52840 (primary), nRF52833
+
+**New files:** `src/platform/nrf52/NRF52BLEMesh.h` / `NRF52BLEMesh.cpp`
+
+```cpp
+#pragma once
+#if HAS_BLE_MESH && defined(ARCH_NRF52)
+
+#include "mesh/BLEMeshHandler.h"
+#include <bluefruit.h>
+
+class NRF52BLEMesh : public BLEMeshHandler {
+public:
+    void start() override;
+    void stop() override;
+    bool onSend(const meshtastic_MeshPacket *mp) override;
+
+private:
+    // Advertising mode
+    void startScanning();
+    static void onScanCallback(ble_gap_evt_adv_report_t *report);
+    void broadcastViaAdv(const uint8_t *data, size_t len);
+
+    // GATT mode
+    BLEService meshService;
+    BLECharacteristic meshTxChar;
+    BLECharacteristic meshRxChar;
+    void setupMeshService();
+    static void onMeshWrite(uint16_t connHandle, BLECharacteristic *chr,
+                            uint8_t *data, uint16_t len);
+    void sendViaGATT(const uint8_t *data, size_t len);
+
+    // Peers
+    struct BLEPeer {
+        NodeNum nodeNum;
+        ble_gap_addr_t addr;
+        int8_t rssi;
+        uint32_t lastSeenMs;
+        uint16_t connHandle;
+    };
+    std::vector<BLEPeer> peers;
+};
+
+#endif
+```
+
+### 4.1 Advertising mode
+
+nRF52840 supports BLE 5.0 extended advertisements (up to 247 bytes).
+
+**Bluefruit APIs:**
+
+- `Bluefruit.Scanner.setRxCallback()` — scan result callback
+- `Bluefruit.Scanner.start()` / `.stop()` — control scanning
+- `Bluefruit.Advertising` — for standard adv
+- Raw SoftDevice `sd_ble_gap_adv_set_configure()` if Bluefruit doesn't expose extended adv data
+
+**Implementation:**
+
+- Use Bluefruit Scanner for RX (filter by Meshtastic manufacturer ID)
+- For TX, either use Bluefruit Advertising API or drop to raw SoftDevice for extended adv payloads
+
+### 4.2 GATT mode
+
+Same service structure as ESP32, using Bluefruit GATT APIs:
+
+```cpp
+meshService = BLEService(MESH_RELAY_SERVICE_UUID);
+meshTxChar = BLECharacteristic(MESH_TX_CHAR_UUID);
+meshTxChar.setProperties(CHR_PROPS_WRITE_WO_RESP);
+meshTxChar.setWriteCallback(onMeshWrite);
+meshTxChar.setMaxLen(512);
+
+meshRxChar = BLECharacteristic(MESH_RX_CHAR_UUID);
+meshRxChar.setProperties(CHR_PROPS_NOTIFY);
+meshRxChar.setMaxLen(512);
+```
+
+**Peer connections:**
+
+- nRF52840 SoftDevice S140 supports up to 20 concurrent connections
+- Use `Bluefruit.Central` for outbound connections to mesh peers
+- Bluefruit supports simultaneous peripheral (phone) + central (mesh peers)
+
+### 4.3 Coexistence with phone BLE
+
+Existing phone service ([NRF52Bluetooth.cpp](src/platform/nrf52/NRF52Bluetooth.cpp)) uses peripheral role:
+
+- Keep phone API service as-is
+- Add mesh relay service alongside it
+- Scanner shared between peer discovery and mesh RX (filter by service UUID or manufacturer data)
+- SoftDevice connection budget: 1 peripheral (phone) + N central (mesh peers)
+
+### 4.4 nRF52 extras
+
+| Feature                | nRF52840 | nRF52833 |
+| ---------------------- | -------- | -------- |
+| Extended Adv           | Yes      | Yes      |
+| Max Connections        | 20       | 20       |
+| RAM per connection     | ~1.8KB   | ~1.8KB   |
+| Coded PHY (Long Range) | Yes      | Yes      |
+
+**Coded PHY:** BLE Coded PHY (125kbps) provides ~4x range vs 1Mbps PHY. Could be used for extended-range BLE mesh links as a configuration option.
+
+---
+
+## Phase 5: Router Integration
+
+### 5.1 Hook into Router::send()
+
+**File:** [src/mesh/Router.cpp](src/mesh/Router.cpp) — add right next to UDP handler:
+
+```cpp
+#if HAS_BLE_MESH
+    if (bleMeshHandler && config.bluetooth.mesh_enabled) {
+        bleMeshHandler->onSend(p);
+    }
+#endif
+```
+
+### 5.2 Global handler instance
+
+**File:** [src/main.h](src/main.h):
+
+```cpp
+#ifdef HAS_BLE_MESH
+#include "mesh/BLEMeshHandler.h"
+extern BLEMeshHandler *bleMeshHandler;
+#endif
+```
+
+**File:** [src/main.cpp](src/main.cpp):
+
+```cpp
+#ifdef HAS_BLE_MESH
+BLEMeshHandler *bleMeshHandler = nullptr;
+#endif
+
+// In setup():
+#ifdef HAS_BLE_MESH
+    #if defined(ARCH_ESP32)
+        bleMeshHandler = new NimbleBLEMesh();
+    #elif defined(ARCH_NRF52)
+        bleMeshHandler = new NRF52BLEMesh();
+    #endif
+    bleMeshHandler->start();
+#endif
+```
+
+### 5.3 NODENUM_BROADCAST_NO_LORA
+
+Already reserved ([MeshTypes.h:13-14](src/mesh/MeshTypes.h#L13-L14)) and already dropped by LoRa ([RadioLibInterface.cpp:170](src/mesh/RadioLibInterface.cpp#L170)). BLE mesh handler should still send packets addressed to `NODENUM_BROADCAST_NO_LORA` — this is its purpose.
+
+### 5.4 Feature flag
+
+**File:** `src/configuration.h` or per-variant `platformio.ini`:
+
+```cpp
+#define HAS_BLE_MESH 1  // Enable BLE mesh transport
+```
+
+Disabled by default. Enabled per-board in variant configs for boards with sufficient BLE capability.
+
+---
+
+## Phase 6: Peer Discovery & Management
+
+### 6.1 Discovery methods
+
+1. **Passive scanning**: Listen for Meshtastic manufacturer data in BLE advertisements
+2. **Service discovery**: Scan for Mesh Relay Service UUID (GATT mode)
+3. **NodeDB integration**: Update `meshtastic_NodeInfoLite` with BLE reachability when a peer is discovered
+
+### 6.2 Peer table
+
+```cpp
+struct BLEMeshPeer {
+    NodeNum nodeNum;
+    // Platform-specific BLE address (ble_addr_t on ESP32, ble_gap_addr_t on nRF52)
+    uint8_t addr[6];
+    uint8_t addrType;
+    int8_t rssi;
+    uint32_t lastSeenMs;
+    uint16_t connHandle;      // 0 = not connected
+    uint8_t failedConnAttempts;
+};
+```
+
+Max peers: configurable (default 8), bounded by platform connection limits.
+
+### 6.3 Connection policy (GATT mode)
+
+- Auto-connect if RSSI > threshold and slots available
+- Disconnect stale peers (no traffic for N minutes)
+- Prefer advertising for broadcasts, GATT for directed/reliable
+- Exponential backoff on failed connection attempts
+
+---
+
+## Phase 7: Power Management
+
+### 7.1 Scan duty cycling
+
+```
+Active scanning:    ~15mA (nRF52), ~90mA (ESP32)
+Advertising:        ~5mA peak per event
+Idle:               ~0mA additional
+
+Default strategy:
+- Scan window: 50ms every 500ms (10% duty cycle)
+- ~1.5mA average on nRF52, ~9mA on ESP32
+- Configurable via BleMeshConfig.interval_ms
+```
+
+### 7.2 Sleep integration
+
+- Light sleep: pause scanning, continue advertising at reduced rate
+- Deep sleep: disable BLE mesh entirely
+- Hook into existing power management observers
+
+### 7.3 Role-based behavior
+
+| Device Role | BLE Mesh Behavior                           |
+| ----------- | ------------------------------------------- |
+| CLIENT      | Scan on-demand, advertise when sending      |
+| CLIENT_MUTE | Receive only, no rebroadcast                |
+| ROUTER      | Continuous scan+advertise, max connections  |
+| ROUTER_LATE | Delayed rebroadcast (same as LoRa behavior) |
+| SENSOR      | Minimal: advertise telemetry only           |
+
+---
+
+## Phase 8: Testing & Validation
+
+### 8.1 Unit tests
+
+- BLE wire format encode/decode roundtrip
+- PacketHistory deduplication across LoRa + BLE
+- Peer table management (add, prune, limits)
+- Echo prevention (don't re-send BLE-sourced packets over BLE)
+
+### 8.2 Integration tests
+
+- Two ESP32 nodes: BLE-only mesh (no LoRa)
+- Two nRF52 nodes: BLE-only mesh
+- Three nodes: multi-hop BLE relay
+- Hybrid: Node A (LoRa+BLE) <-> Node B (BLE only) <-> Node C (LoRa+BLE)
+- Phone API + BLE mesh coexistence
+- Power consumption profiling
+
+### 8.3 Compatibility matrix
+
+| Test          | ESP32       | ESP32-S3 | ESP32-C3 | ESP32-C6 | nRF52840 |
+| ------------- | ----------- | -------- | -------- | -------- | -------- |
+| Adv mode      | GATT only\* | Yes      | Yes      | Yes      | Yes      |
+| GATT mode     | Yes         | Yes      | Yes      | Yes      | Yes      |
+| Phone coexist | Yes         | Yes      | Yes      | Yes      | Yes      |
+| Multi-hop     | Yes         | Yes      | Yes      | Yes      | Yes      |
+
+\*ESP32 (BLE 4.2): legacy adv limited to 31B, use GATT-only mode
