## 1. Introduction
### 1.1. Q: What is MeshCore?
**A:** MeshCore is free and open source
**A:** MeshCore is a multi platform system for enabling secure text based communications utilising LoRa radio hardware. It can be used for Off-Grid Communication, Emergency Response & Disaster Recovery, Outdoor Activities, Tactical Security including law enforcement and private security and also IoT sensor networks. ([source](https://meshcore.co.uk/))
MeshCore is free and open source:
* MeshCore is the routing and firmware etc, available on GitHub under MIT license
* There are clients made by the community, such as the web clients, these are free to use, and some are open source too
* The cross platform mobile app developed by [Liam Cottle](https://liamcottle.net) for Android/iOS/PC etc is free to download and use

### 4.4. Q: What size of SD card does the T-Deck support?
**A:** Users have had no issues using 16GB or 32GB SD cards. Format the SD card to **FAT32**.
### 4.5. Q: How do I get maps on T-Deck?
### 4.5. Q: what is the public key for the default public channel?
**A:**
T-Deck uses the same key the smartphone apps use but in base64
`izOH6cXN6mrJ5e26oRXNcg==`
The third character is the capital letter 'O', not zero `0`
Once you have the tiles downloaded, copy the `\tiles` folder to the root of your T-Deck's SD card.
### 4.7. Q: How to unlock deeper map zoom and server management features on T-Deck?
### 4.8. Q: How to unlock deeper map zoom and server management features on T-Deck?
**A:** You can download, install, and use the T-Deck firmware for free, but it has some features (map zoom, server administration) that are enabled if you purchase an unlock code for \$10 per T-Deck device.
**A:** You can customise the sounds on the T-Deck, just by placing `.mp3` files onto the `root` dir of the SD card. `startup.mp3`, `alert.mp3` and `new-advert.mp3`

### 4.12. Q: What is the 'Import from Clipboard' feature on the t-deck and is there a way to manually add nodes without having to receive adverts?
**A:** 'Import from Clipboard' is for importing a contact via a file named 'clipboard.txt' on the SD card. The opposite, is in the Identity screen, the 'Card to Clipboard' menu, which writes to 'clipboard.txt' so you can share yourself (call these 'biz cards', that start with "meshcore://...")

### 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)
- Merged bin overwrites everything including the bootloader, existing Bluetooth pairing database, but keeps configurations.
- Right click on the file name and copy the link and note it for later use here is an example: `https://flasher.meshcore.dev/releases/download/companion-v1.7.1/Heltec_v3_companion_radio_ble-v1.7.1-165fb33.bin`
- Run:
- `wget https://flasher.meshcore.dev/releases/download/companion-v1.7.1/Heltec_v3_companion_radio_ble-v1.7.1-165fb33.bin` to download the firmware file for your device type. or the version you need - USB, BLE, Repeater, Room Server, merged bin or non-merged bin
- If the above wget command only downloads a very small file (10K bytes instead of more than 100K byte, use this command instead:
- Right click on the file name and copy the link and note it for later use here is an example: `https://flasher.meshcore.dev/releases/download/companion-v1.7.1/RAK_4631_companion_radio_ble-v1.7.1-165fb33.zip`
- Run:
- `wget https://flasher.meshcore.dev/releases/download/companion-v1.7.1/RAK_4631_companion_radio_ble-v1.7.1-165fb33.zip` to download the firmware file for your device type. or the version you need - USB, BLE, Repeater, Room Server, ZIP file only
- Confirm the `ttyXXXX` device path on your Raspberry Pi:
- Go to `/dev` directory, run ls command to find confirm your device path
To manage a repeater or room server connected to a Pi over USB serial using shell commands, you need to install `picocom`. To install `picocom`, run the following command:
- `sudo apt install picocom`
To start managing your USB serial-connected device using picocom, use the following command:
- `picocom -b 115200 /dev/ttyUSB0 --imap lfcrlf`
