 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.

-#### 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.  

 A repeater can be remotely administered using a T-Deck running the MeshCore firwmware with remote admistration features unlocked, or from a BLE Companion client connected to a smartphone running the MeshCore app.

 A room server is a simple BBS server for sharing posts. T-Deck devices running MeshCore firmware or a BLE Companion client connected to a smartphone running the MeshCore app can connect to a room server. 

 room servers store message history on them, and push the stored messages to users.  Room servers allow roaming users to come back later and retrieve message history.  Contrast to channels, messages are either received  when it's sent, or not received and missed if the a room user is out of range.  You can think  of room servers like email servers where you can come back later and get your emails from your mail server

-### 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.

 **A:** For T-Deck Plus, the GPS baud rate should be set to **38400**. Also, a number of T-Deck Plus devices were found to have the GPS module installed upside down, with the GPS antenna facing down instead of up. If your T-Deck Plus still doesn't get any satellite lock after setting the baud rate to 38400, you might need to open up the device to check the GPS orientation.

-### 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  sends back to the sender a delivery report 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.  Admistrators of repeaters get to set the rules of their repeaters.

-### Q: How do I add a node to the [MeshCore Map]([url](https://meshcore.co.uk/map.html))
+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.

+
+### 5.12. Q: How do I add a node to the [MeshCore Map]([url](https://meshcore.co.uk/map.html))
 **A:** From the smartphone app, connect to a BLE Companion radio
 - To add the BLE Companion radio your smartphone is connected to to the map, tap the `advert` icon, then tap `Advert (To Clipboard)`.  
 - To add a Repeater or Room Server to the map, tap the 3 dots next to the Repeater or Room Server you want to add to the map, then tap `Share (To Clipboard)`.  
 - Go to the [MeshCore Map web site]([url](https://meshcore.co.uk/map.html)), tap the plus sign on the lower right corner and paste in the meshcore://... blob, then tap `Add Node`
-    
+
+### 5.13. Q: Can I use a Raspberry Pi to update a MeshCore radio?
+** A:** Yes.
+You will need to install picocom on the pi.
+`sudo apt install picocom`
+
+Then run the following commands to setup the repeater.
+```
+picocom -b 115200 /dev/ttyUSB0 --imap lfcrlf
+set name your_repeater_name
+time epoch_time
+password your_unique_password
+set advert.interval 240
+advert
+```
+Note: If using a RAK the path will most likely be /dev/ttyACM0
+
+Epoch time comes from https://www.epochconverter.com/
+
+You can also flash the repeater using esptool.  You will need to install esptool with the following command...
+
+`pip install esptool --break-system-packages`
+
+Then to flash the firmware to Heltec, obtain the .bin file from https://flasher.meshcore.co.uk/ (download all firmware link)
+
+For Heltec:
+`esptool.py -p /dev/ttyUSB0 --chip esp32-s3 write_flash 0x00000 firmware.bin`
+
+If flashing a visual studio code build bin file, flash with the following offset:
+`esptool.py -p /dev/ttyUSB0 --chip esp32-s3 write_flash 0x10000 firmware.bin`
+
+For Pi
+Download the zip from the online flasher website and use the following command:
+
+Note: Requires adafruit-nrfutil command which can be installed as follows.
+`pip install adafruit-nrfutil --break-system-packages`
+
+```
+adafruit-nrfutil --verbose dfu serial --package t1000_e_bootloader-0.9.1-5-g488711a_s140_7.3.0.zip -p /dev/ttyACM0 -b 115200 --singlebank --touch 1200

+### 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.
