 ## 🔍 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.

If it's already encoded 4 times, it will reject the packet.  If the packet uses 2-byte path size, and repeater's own ID/hash is already encoded 2 times, it rejects.

+#### 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
+region save

+**A:** You can generate a new private key and specify the first byte of its public key here: <https://gessaman.com/mc-keygen>

 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.

 ### 3.9.1. 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.

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 are 21 or 32 hops away.

 ### 5.3. Q: What happens when a node learns a route via a mobile repeater, and that repeater is gone?
-
-**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.

Or you can set the path manually if you know a specific repeater to use to reach that destination.

 In the case if users are moving around frequently, and the paths are breaking, they just see the phone client retries and revert to flood to attempt to re-establish a path.

 ### 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.

 ### 5.5. Q: Do public channels always flood? Do private channels always flood?
-
-**A:** Yes, group channels are A to B, so there is no defined path.  They have to flood.  Repeaters can however deny flood traffic up to some hop limit, with the `set flood.max` CLI command. Administrators of repeaters get to set the rules of their repeaters.

 **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.

+### 7.1. Q: How to update nRF (RAK, T114, Seeed XIAO) companion, repeater and room server firmware over the air using the new simpler DFU app?
 **A:** The steps below work on both Android and iOS as nRF has made both apps' user interface the same on both platforms:

 1. Download nRF's DFU app from iOS App Store or Android's Play Store, you can find the app by searching for `nrf dfu`, the app's full name is `nRF Device Firmware Update`
-2. On https://flasher.meshcore.io, download the **ZIP** version of the firmware for your nRF device (e.g. RAK or Heltec T114 or Seeed Studio's Xiao)
-3. From the MeshCore app, login remotely to the repeater you want to update with admin privilege

 4. Go to the Command Line tab, type `start ota` and hit enter.
-5. you should see `OK` to confirm the repeater device is now in OTA mode
-6. Run the DFU app,tab `Settings` on the top right corner
-7. Enable `Packets receipt notifications`, and change `Number of Packets` to 10 for RAK, 8 for T114.  8 also works for RAK.
-9. Select the firmware zip file you downloaded
-10. Select the device you want to update. If the device you want to update is not on the list, try enabling`OTA` on the device again
-11. If the device is not found, enable `Force Scanning` in the DFU app
-12. Tab the `Upload` to begin OTA update
-13. If it fails, try turning off and on Bluetooth on your phone.  If that doesn't work, try rebooting your phone.  If you keep getting failures at the "Enabling Bootloader" step, try forgetting the NRF board in your IOS or Andriod device's bluetooth settings and re-pair it through the DFU app.
-14. Wait for the update to complete.  It can take a few minutes.   
-15. It is strongly recommended that you install and use the OTAFIX bootloader at https://github.com/oltaco/Adafruit_nRF52_Bootloader_OTAFIX.

 ### 7.3. Q: Is there a way to lower the chance of a failed OTA device firmware update (DFU)?
+**A:** Yes, developer `che aporeps` has an enhanced OTA DFU bootloader for nRF52 based devices. With this bootloader, if it detects that the application firmware is invalid, it falls back to OTA DFU mode so you can attempt to flash again to recover. This bootloader has other changes to make the OTA DFU process more fault tolerant.

 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`).

Kemal Hadimli	bb781ff10a	companion_radio: opt-in KEEP_DISPLAY_ON_USB to keep OLED on while powered AUTO_OFF_MILLIS is a power-save feature aimed at battery use. When the board reports isExternalPowered() == true (USB or other DC source), blanking the screen serves no purpose — there's nothing to conserve. But OLEDs are vulnerable to burn-in with static content, so this behaviour is gated behind a new build flag KEEP_DISPLAY_ON_USB. Default is unchanged from upstream — the display blanks after AUTO_OFF_MILLIS on USB or battery. Variants that ship with an LCD instead of an OLED (e.g. heltec_t096) can opt in by adding -D KEEP_DISPLAY_ON_USB to their env, gaining always-on-while-powered without exposing OLED users to burn-in risk. When the flag is enabled, the implementation refreshes _auto_off every loop iteration while externally powered, so the timer naturally counts a fresh AUTO_OFF_MILLIS window from the moment power is removed — no instantaneous-blank-on-unplug. Applied to all three companion_radio UI flavours (ui-new, ui-tiny, ui-orig). Boards without an isExternalPowered() override use the base-class default in MeshCore.h (returns false), so battery-powered behaviour is unchanged everywhere.

Nick Dunklee	59cee5c8a0	feat: Integrate BME680 Bosch BSEC support for RAK4631 This is a consolidation of my changes for BME680 on RAK4631 nodes. I will close my other PRs related to this and link back to this one. Background on change: This change replaces the Adafruit BME680 driver on RAK4631 with the Bosch BSEC library. Other boards continue to use the existing Adafruit path via ENV_INCLUDE_BME680. This makes the IAQ portion of the sensor functional, and more accurate. It also contains the math and/or CayenneLPP fixes from my other PRs. The Bosch code also appears to handle calibrating sensor aging as well, whereas the Adafruit code is just looking at blind values that can drift with time. Pretty cool to see this shooting out useful data! RAK4631 platform.io is set to override to ENV_INCLUDE_BME680_BSEC while leaving the Adafruit code for other node types. (If this becomes applicable for other node types in future, awesome! I just don't have hardware to test against.) Using the BSEC library introduces IAQ sensor calibration, and saves the calibration state periodically so it does not have to calibrate again later. At startup the IAQ sensor takes 30 minutes to heat and to hit a baseline, then starts calibrating. Once calibrated, it will save those settings and will only write settings again if calibration falls back and restores back to state 3. This fix also has the gas resistance math fix that was in [pull 2146](https://github.com/meshcore-dev/MeshCore/pull/2146) so the adafruit path also can at least show accurate values instead of looping negative. Also includes the fix from [pull 2149](https://github.com/meshcore-dev/MeshCore/pull/2149) so the pressure output isn't truncated to 1hPa steps. Fixes/Changes: - Add bsec_config_iaq[] with the 3.3V/3s-LP/28d calibration profile - BSEC init applies setConfig() for voltage-correct heater targeting - IAQ, heat-compensated temperature/humidity, pressure, and altitude reported over CayenneLPP - IAQ accuracy reported as analog input over CayenneLPP (0,1,2,3) - Calibration state persisted to /bsec_state.bin on nRF52 internal flash; written only when iaqAccuracy improves to >= 2, should keep write frequency well within flash endurance over device lifetime - Fix non-BSEC query_bme680: float pressure division, addGenericSensor for gas resistance (was addAnalogInput, overflows at > 327 Ohm) - loop() correctly gated for both GPS and BSEC-only builds - Add fix_bsec_lib.py extra_script to resolve nRF52840 hard-float ABI mismatch in Bosch's PlatformIO packaging, silly Bosch One general note outside of this code change: I noticed while BME680 _functions_ in companion nodes, since companion nodes run Bluetooth, BLE preempts the CPU, and can do so mid-I2C-transaction. This can cause the BME680 to see an anomaly and drop calibration and start a recalibrate. This is behavior that will exist (and has existed) regardless of using the Adafruit or Bosch paths. This particular companion behavior does not seem to occur in sensor or repeater nodes since their BLE is off. Probably affects other I2C devices as well.

jirogit	f224a325e6	fix: enable radio.rxgain CLI command for LR1110 (T1000-E) USE_LR1110 was missing from the preprocessor guard in CommonCLI.cpp, causing both get and set to fail silently on T1000-E: - get radio.rxgain returned the full radio config string (fell through to the memcmp("radio", 5) branch) - set radio.rxgain returned "unknown config" (no branch matched) Fix: add -D USE_LR1110 to variants/t1000-e/platformio.ini and include USE_LR1110 in the #if guard on both get and set branches. CustomLR1110Wrapper already implements setRxBoostedGainMode() and getRxBoostedGainMode() via the RadioLibWrapper virtual interface, so no radio-layer changes are required. Tested on T1000-E: get/set/persist all confirmed working.	2026-05-01 00:31:31 -07:00
