 ## 🔍 What is MeshCore?

 MeshCore now supports a range of LoRa devices, allowing for easy flashing without the need to compile firmware manually. Users can flash a pre-built binary using tools like Adafruit ESPTool and interact with the network through a serial console.
-MeshCore provides the ability to create wireless mesh networks, similar to Meshtastic and Reticulum but with a focus on lightweight multi-hop packet routing for embedded projects. Unlike Meshtastic, which is tailored for casual LoRa communication, or Reticulum, which offers advanced networking, MeshCore balances simplicity with scalability, making it ideal for custom embedded solutions, where devices (nodes) can communicate over long distances by relaying messages through intermediate nodes. This is especially useful in off-grid, emergency, or tactical situations where traditional communication infrastructure is unavailable.

-# Security Policy
-
-## Supported Versions
-
-Security fixes are applied to the latest release only. We do not backport
-fixes to older versions.
-
-| Version | Supported |
-|---------|-----------|
-| 1.15+ | ✅ |
-| <1.15 | ❌ |
-
-## Reporting a Vulnerability
-
-**Please do not report security vulnerabilities through public GitHub issues.**
-
-Use GitHub's private vulnerability reporting instead:
-1. Go to the **Security** tab of this repository
-2. Click **Report a vulnerability**
-3. Fill in the details and submit
-
-### What to include
-
-A useful report tells us:
- Which component or file is affected
- What an attacker can do (impact) and under what conditions
- A minimal reproduction case or proof-of-concept if you have one
- Whether you believe it is remotely exploitable
-
-You do not need a working exploit to report. An incomplete report is better
-than no report.
-
-## What to expect
-
-This is a volunteer-maintained open-source project. We will do our best to
-respond in a reasonable timeframe, but cannot commit to specific deadlines.
-
-We ask that you give us a fair opportunity to investigate and address the
-issue before any public disclosure. If you have not heard back after
-**90 days**, feel free to follow up or proceed with disclosure at your
-discretion.
-
-## Scope
-
-In scope:
- Remote code execution, memory corruption, or denial-of-service via crafted
-  radio packets
- Authentication or encryption bypasses
- Vulnerabilities in the packet routing or path handling logic
-
-Out of scope:
- Physical access attacks (e.g., JTAG, UART extraction of keys)
- Regulatory compliance (duty cycle, frequency restrictions)
- Jamming or other physical-layer radio interference
- Issues in third-party libraries (RadioLib, Crypto, etc.) — report those
-  upstream
- "Best practice" suggestions without a demonstrated attack path

-**Notes:**
- This controls a software-selectable external LoRa FEM transmit gain where the board supports it.
- On Station G3, remove the PA PL1 jumper to allow software control. `on` selects PA PL1 high/short and `off` selects PA PL1 low/open. The PA PL2 hardware jumper determines whether this switches between power levels 1/3 or 2/4.
- Select an operating level and SX1262 transmit power that comply with local RF limits and the Station G3 power-supply requirements.
- The setting is saved immediately, but on Station G3 the level is applied to the hardware at the start of the next transmit, so that the PA supply rail is never re-targeted while the PA is being driven. `get` reports the configured state, which may lead the hardware until the node next transmits.

-#### Define region hierarchy (single line)
-**Usage:**
- `region def <token> [<token> ...]`
-
-**Parameters (tokens):** Space-separated. A logical **cursor** starts at the wildcard `*`.
-
- **`name`** — Create `name` as a child of the current cursor (equivalent to `region put name` with the cursor as parent). Cursor moves to `name`.
- **`name|jump`** *(or `name,jump`)* — Create `name` as a child of the current cursor, then move the cursor to `jump` (must already exist on the node, or have been created earlier in this command). `jump` is **not** the parent of `name`; use this form to pop back up and start another branch.
-
-**Behavior:** Each created region defaults to flood-allowed (same as `region put`). The reply is the resulting region tree (same format as bare `region`); review it before running `region save` to persist. On error, the reply is `Err - ...` and any regions placed before the failure remain on the node, just like a partial chain of `region put`.
-
-**Existing regions:** `region def` does not clear the existing tree — if a name already exists, its parent is updated to the current cursor; otherwise a new region is created. To start from scratch, `region remove` the unwanted regions first.
-
-**Limits:** Repeater serial accepts one line up to **160 characters**. For larger trees, split across multiple `region def` commands; the cursor resets to `*` between commands, so lead the next command with `child|ancestor` to reposition. Each token splits at most once on `|` — `region def a|b|c|d` is not a flat-list shorthand; see the flat-list example below.
-
-**Example — linear chain** (each token becomes a child of the previous):
-```
-region def a b c d e
-region save
-```
-
-**Example — branched tree** (equivalent to `region put a`, `region put b a`, `region put c b`, `region put d c`, `region put e b`, `region put f e`):
-```
-region def a b c d|b e f
-region save
-```
-
-**Example — error and partial state:**
-```
-region def a b c|nope d
-```
-The reply is `Err - unknown jump: nope`. `a`, `b`, and `c` were placed before the failure; `d` was not. Run `region` to inspect, then re-run with a corrected jump or repair with `region remove` / `region put`.
-
-**Example — flat list** (each region a child of `*`). Use `|*` after each token to pop the cursor back to the root before the next token:
-```
-region def a|* b|* c|* d|* e|* f

 Having multiple repeaters with the same first byte ID does not negatively affect the mesh or its functionality. Flood and pathed packets will still reach their destinations. First byte ID collision makes traceroute and path analysis harder because these tools don't know exactly which of the two (or more) colliding repeaters is the one in the path.

 Best practice is when you set up a new repeater, choose a public key that is not in use. If it is not possible to find a unique first byte for your repeater's public key, choose one that is unique within about 10 miles (16 km) to minimize collision with nearby repeaters.

+### 3.9. Q: What is multi-byte support?  What do 1-byte, 2-byte, 3-byte adverts and messages mean?
+
 **A:**
-The original MeshCore protocol design uses the first byte of a repeater's public key to denote the repeater in a path. And with 1 byte for each repeater in the path, MeshCore packets can travel as many as 64 hops.
+The original MeshCore protocol design uses the first byte of a repeater's public key to denote the repeater in a path.  And with 1 byte for each repeater in the path, MeshCore packets can travel as many as 64 hops.  

-However, with 1 byte, there are only 254 unique IDs (exclude 00 and FF which are reserved). Many meshes group have multiple repeaters with the same first byte in their public keys. Packets continue to pass through repeaters and the mesh is not harmed in any way. It does make it harder for tools to analyze paths with duplicated repeater IDs.

-Firmware version 1.14 and newer introduces the ability for repeaters to advert with 1-, 2-, or 3-byte adverts. Companions can also send out channel and direct messages with 1-, 2-, or 3-byte path. Adverts and messages sent in 1-byte path is compatible with repeater firmware older or newer than 1.14.

 ### 3.9.1. Q: **What path hash sizes will my repeater forward?**
+
 Repeaters running firmware 1.14+ repeat packets sent with 1-, 2-, or 3-byte path hash. Repeaters on firmware older than 1.14 only repeat 1-byte path hash packets and silently drop 2- and 3-byte packets.

 ### 3.9.2. Q: **What determines a packet's path hash size?**
+
 The original packet sender determines the path hash size. The most common original sender is a companion app. The other common original sender is a repeater, when it broadcasts its advert.

 ### 3.9.3. Q: **How do I change my companion's path hash size?**
-As of firmware version 1.14 and MeshCore app version 1.41.0, in the MeshCore app, you can set your companion's message path hash size in `Settings (gear icon)`, `Experimental Settings`.

+As of firmware version 1.14 and MeshCore app version 1.41.0, in the MeshCore app, you can set your companion's message path hash size in `Settings (gear icon)`, `Experimental Settings`. 

 Until your regional mesh has the vast majority of the repeaters updated to 1.14+ firmware, it is recommended to keep your companion at the default 1-byte because pre-1.14 repeaters will silently drop messages with larger path hashes.

 ### 3.9.4. Q: **What does the CLI command `path.hash.mode` do on a repeater?**
+
 This CLI command `path.hash.mode` *only* controls the path hash size used in a repeater's own advert broadcasts. It does **NOT** affect which packets the repeater forwards. A repeater with firmware 1.14+ always forward 1-, 2-, and 3-byte packets regardless of this setting.

 ### 3.9.5. Q: **Why use 2- or 3-byte path hash for adverts?**

-A longer path hash helps tools like the LetsMesh.net Analyzer and MeshMapper disambiguate repeaters more reliably. With only 1 byte, the chance of different repeaters having the same first byte in their public key is high, making it harder to tell them apart in mesh network analysis. Since this only affects adverts, there's no downside. 2- and 3-byte adverts don't travel as far as 1-byte adverts, but it is not important for MeshCore nodes to hear a repeater's advert that is 21 or 32 hops away.

 ### 3.9.6. Q: **When can we move away from 1-byte path hash for channel and direct messages?**

-You should move to send 2-byte or 3-byte channel and direct messages when the vast majority of the repeaters in your regional mesh are updated to firmware version 1.14 or newer. Setting your repeater's `path.hash.mode` to 1 (for 2-byte path hash) or 2 (for 3-byte path hash) now helps the community gauge to how many repeaters have updated to 1.14+. Please work with your MeshCore community together to decide when to switch to 2-byte path or 3-byte path for channel and direct messages.

If your T-Deck Plus still doesn't get any satellite lock after setting the baud rate to 38400, you might need to open the device to check the GPS orientation.

-**A:** If you used to reach a node through a repeater and the repeater is no longer reachable, the client will send the message using the existing (but now broken) known path, the message will fail after 3 retries, and the app will reset the path and send the message as flood on the last retry by default. This can be turned off in settings. If the destination is reachable directly or through another repeater, the new path will be used going forward. Or you can set the path manually if you know a specific repeater to use to reach that destination.

 ### 5.4. Q: How does a node discover a path to its destination and then use it to send messages in the future, instead of flooding every message it sends like Meshtastic?
-Routes are stored in sender's contact list. When you send a message the first time, the message first gets to your destination by flood routing. When your destination node gets the message, it will send back a delivery report to the sender with all repeaters that the original message went through. This delivery report is flood-routed back to you the sender and is a basis for future direct path. When you send the next message, the path will get embedded into the packet and be evaluated by repeaters. If the hop and address of the repeater matches, it will retransmit the message, otherwise it will not retransmit, hence minimizing utilization.

 **A:** ATAK is not currently on MeshCore's roadmap.

-MeshCore would not be best suited to ATAK because MeshCore:
-
- clients do not repeat and therefore you would need a network of repeaters in place
- will not have a stable path where all clients are constantly moving between repeaters
+Meshcore would not be best suited to ATAK because MeshCore:
+clients do not repeat and therefore you would need a network of repeaters in place
+will not have a stable path where all clients are constantly moving between repeaters

 MeshCore clients would need to reset path constantly and flood traffic across the network which could lead to lots of collisions with something as chatty as ATAK.

 This could change in the future if MeshCore develops a client firmware that repeats.

-### 7.8. Q: How do I use Ethernet with a RAK4631?
+### 7.7. Q: I have a Station G2, or a Heltec V4, or an Ikoka Stick, or a radio with a EByte E22-900M30S or a E22-900M33S module, what should their transmit power be set to?
 **A:**
-MeshCore supports Ethernet on RAK4631 boards using the [RAK13800](https://docs.rakwireless.com/product-categories/wisblock/rak13800/datasheet/) WisBlock Ethernet module (based on the W5100S chip).
+For companion radios, you can set these radios' transmit power in the smartphone app.  For repeater and room server radios, you can set their transmit power using the command line command `set tx`.  You can get their current value using command line command `get tx`

-**Hardware required:**
- RAK4631 WisBlock Core
- RAK19007 or RAK19018 WisBlock Base Board (with an available IO slot)
- RAK13800 WisBlock Ethernet module
- Ethernet cable connected to a network with a DHCP server

-**Firmware:**
-Flash one of the Ethernet-enabled firmware variants:
- `RAK_4631_repeater_ethernet` - Repeater with Ethernet CLI access
- `RAK_4631_room_server_ethernet` - Room server with Ethernet CLI access
- `RAK_4631_companion_radio_ethernet` - Companion radio over Ethernet (replaces BLE)
+  ⚠️ **WARNING: Set these values at your own risk. Incorrect power settings can permanently damage your radio hardware.**

-**Connecting:**
- The device obtains an IP address via DHCP automatically on boot.
- For repeaters and room servers, connect to the device on TCP port 23 using any TCP client (e.g. `nc <ip> 23` or PuTTY in raw mode). This gives you the same CLI available over serial/USB.
- For companion radio firmware, the Ethernet interface replaces BLE as the transport to companion apps. Connect on TCP port 5000 (same as the WiFi companion radio).
- Use the `eth.status` CLI command to check connection status and see the assigned IP address.

+| Type | Value | Data | Description |
+|------|-------|------|-------------|
 | Data | `0x00` | Raw packet | Received packet from radio |

 Data frames carry raw packet data only, with no metadata prepended. The Data command payload is limited to 255 bytes to match the MeshCore maximum transmission unit (MAX_TRANS_UNIT); frames larger than 255 bytes are silently dropped. The KISS specification recommends at least 1024 bytes for general-purpose TNCs; this modem is intended for MeshCore packets only, whose protocol MTU is 255 bytes.

-Only one packet may be pending for radio transmission at a time. If the host sends a second Data frame before the first has completed, the modem responds with Error (0xF1) and TxBusy (0x07).
-
-### Host Output Backpressure
-
-Outbound frames are encoded into a 2-slot queue and flushed when serial output space is available; `loop()` never blocks on writes. Radio TX state advances independently of host read speed. TxDone is retained until it can be queued. If the outbound queue is full, the modem responds with Error (0xF1) and TxBusy (0x07). Hosts should read serial promptly to avoid delayed responses.

 ### Response Sub-commands (TNC to Host)

 Response codes use the high-bit convention: `response = command | 0x80`. Generic and unsolicited responses use the `0xF0`+ range.

 ### Unsolicited Events

 The TNC sends these SetHardware frames without a preceding request:

-**TxDone (0xF8)**: Sent after radio transmission completes. Contains a single byte: 0x01 for success, 0x00 for failure. Delivery to the host may be delayed under serial backpressure but is not dropped.
+**TxDone (0xF8)**: Sent after a packet has been transmitted. Contains a single byte: 0x01 for success, 0x00 for failure.

-**RxMeta (0xF9)**: Sent after each standard data frame (type 0x00) with SNR (1 byte, signed, value x4) and RSSI (1 byte, signed, dBm). Queued with the data frame; omitted if the data frame cannot be queued. Enabled by default; toggle with SetSignalReport. Standard KISS clients ignore this frame.
+**RxMeta (0xF9)**: Sent immediately after each standard data frame (type 0x00) with metadata for the received packet. Contains SNR (1 byte, signed, value x4 for 0.25 dB precision) followed by RSSI (1 byte, signed, dBm). Enabled by default; can be toggled with SetSignalReport. Standard KISS clients ignore this frame.

 The plaintext contained in the ciphertext matches the format described in [plain text message](#plain-text-message). Specifically, it consists of a four byte timestamp, a flags byte, and the message. The flags byte will generally be `0x00` because it is a "plain text message". The message will be of the form `<sender name>: <message body>` (eg., `user123: I'm on my way`).

-The sender name is unverified message text. Group messages contain no sender
-signature, so any channel-key holder can choose any sender name.
