 You need LoRa hardware devices to run MeshCore firmware as clients or server (repeater and room server).

-### Hardware
+#### 1.2.1. Hardware
 To use MeshCore without using a phone as the client interface, you can run MeshCore on a T-Deck or T-Deck Plus. It is a complete off-grid secure communication solution.  

 MeshCore is also available on a variety of 868MHz and 915MHz LoRa devices. For example, RAK4631 devices (19003, 19007, 19026), Heltec V3, Xiao S3 WIO, Xiao C3, Heltec T114, Station G2, Seeed Studio T1000-E. More devices will be supported later.

-### Firmware

 MeshCore has four firmware types that are not available on other LoRa systems. MeshCore has the following:

-#### Companion Radio Firmware
+#### 1.2.3. Companion Radio Firmware

-#### Repeater
+#### 1.2.4. Repeater
 Repeaters are used to extend the range of a MeshCore network. Repeater firmware runs on the same devices that run client firmware. A repeater's job is to forward MeshCore packets to the destination device. It does **not** forward or retransmit every packet it receives, unlike other LoRa mesh systems.

-The native Android and iOS client uses the freemium model and is developed by Liam Cottle, developer of meshtastic map at [meshtastic.liamcottle.net](https://meshtastic.liamcottle.net) on [github ](https://github.com/liamcottle/meshtastic-map)and [reticulum-meshchat on github](https://github.com/liamcottle/reticulum-meshchat).

 The T-Deck firmware is free to download and most features are available without cost.  To support the firmware developer, you can pay for a registration key to unlock your T-Deck for deeper map zoom and remote server administration over RF using the T-Deck.  You do not need to pay for the registration to use your T-Deck for direct messaging and connecting to repeaters and room servers. 


-### Q: What frequencies are supported by MeshCore?
+### 2.3. Q: What frequencies are supported by MeshCore?
 **A:** It supports the 868MHz range in the UK/EU and the 915MHz range in New Zealand, Australia, and the USA. Countries and regions in these two frequency ranges are also supported. The firmware and client allow users to set their preferred frequency.  
 - Australia and New Zealand are on **915.8MHz**
 - UK and EU are on **869.525MHz**
 - Canada and USA are on **910.525MHz**
 - For other regions and countries, please check your local LoRa frequency

+In UK and EU, 867.5MHz is not allowed to use 250kHz bandwidth and it only allows 2.5% duty cycle for clients.  869.525Mhz allows an airtime of 10%, 250KHz bandwidth, and a higher EIRP, therefore MeshCore nodes can send more often and with more power. That is why this frequency is chosen for UK and EU.  This is also why Meshtastic also uses this frequency.

 the rest of the radio settings are the same for all frequencies:  
- Spread Factor (SF): 10  
+- Spread Factor (SF): 11  
 - Coding Rate (CR): 5  
 - Bandwidth (BW): 250.00  

-### Q: What is an "advert" in MeshCore?
+(Originally MeshCore started with SF 10.  recently (as of late April 2025) the community has advocated SF 11 also a viable option for longer range but a little slower transmission. Currently there are MeshCore meshes with SF 10 and SF 11.  Liam Cottle's smartphone app's presets now recommend SF 10 for Australia and SF 11 for all other regions and countries.  EU and UK has SF 10 and SF 11 presets.  Work with your local meshers on deciding with SF number is best for your use cases.  In the future, there may be bridge nodes that can bridge SF 10 and SF 11 (or even different frequencies) traffic.)

+### 2.4. Q: What is an "advert" in MeshCore?
 **A:** 
-Advert means to advertise yourself on the network. In Reticulum terms it would be to announce. In Meshtastic terms it would be the node sending it's node info.
+Advert means to advertise yourself on the network. In Reticulum terms it would be to announce. In Meshtastic terms it would be the node sending its node info.

 MeshCore allows you to manually broadcast your name, position and public encryption key, which is also signed to prevent spoofing.  When you click the advert button, it broadcasts that data over LoRa.  MeshCore calls that an Advert. There's two ways to advert, "zero hop" and "flood".

 * Zero hop means your advert is broadcasted out to anyone that can hear it, and that's it.
-* Flooded means it's broadcasted out, and then repeated by all the repeaters that hear it.
+* Flooded means it's broadcasted out and then repeated by all the repeaters that hear it.

 MeshCore clients only advertise themselves when the user initiates it. A repeater (and room server?) advertises its presence once every 240 minutes. This interval can be configured using the following command:

 `set advert.interval {minutes}`

-### Q: Is there a hop limit?

-### Q: What happens when a node learns a route via a mobile repeater, and that repeater is gone?
+### 5.2. Q: Do MeshCore clients repeat?
+**A:** No, MeshCore clients do not repeat.  This is the core of MeshCore's messaging-first design.  This is to avoid devices flooding the air ware and create endless collisions, so messages sent aren't received.  
+In MeshCore, only repeaters and room server with `set repeat on` repeat.  
+
+### 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.

 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 reestablish a path. 

+### 5.4. Q: How does a node discovery a path to its destination and then use it to send messages in the future, instead of flooding every message it sends like Meshtastic?

-### Q: Is MeshCore open source?
+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.

+### 6.2. Q: A repeater or a client or a room server I expect to see on my discover list (on T-Deck) or contact list (on a smart device client) are not listed.
 **A:**  
 - If your client is a T-Deck, it may not have its time set (no GPS installed, no GPS lock, or wrong GPS baud rate).  
 - If you are using the Android or iOS client, the other client, repeater, or room server may have the wrong time.  

 You can get the epoch time on <https://www.epochconverter.com/> and use it to set your T-Deck clock. For a repeater and room server, the admin can use a T-Deck to remotely set their clock (clock sync), or use the `time` command in the USB serial console with the server device connected.

-### Q: How to connect to a repeater via BLE (bluetooth)?
-**A:** You can't connect to a device running repeater firmware  via bluetooth.  Devices running the BLE companion firmware you can connect to it via bluetooth using the android app

+### 6.5. Q: My Heltec V3 keeps disconnecting from my smartphone.  It can't hold a solid Bluetooth connection.

-**A:** Heltec V3 has a very small coil antenna on its PCB for WiFi and Bluetooth connectivty.  It has a very short range, only a few feet.  It is possible to remove the coil antenna  and replace it with a 31mm wire.  The BT range is much improved with the modification.
