## General

Q: What is Meshtastic?
* Meshtastic is most awesome long range, low power communications service on the planet earth! That's not even an exageration!

Q: Where can I get additional help, ask questions or bond with the Meshtastic community?
* After reading this FAQ and checking out the links on the left, there are two places ... The preferred place is to check out the [Fourm](https://meshtastic.discourse.group). There you can be part of our growing community and search for previosly posts that may be similar to what you're looking for. We also have the [Meshtastic Discord](https://discord.com/invite/UQJ5QuM7vq) server where you may connect with like minded people.

Q: How can I contribute to Meshtastic?
* Everyone contributes in a different way. Join the [Fourm](https://meshtastic.discourse.group) and/or the [Meshtastic Discord](https://discord.com/invite/UQJ5QuM7vq) and introduce yourself. We're all very friendly. If you'd like to pitch in some code, check out the [Developers](https://meshtastic.org/docs/developers) menu on the left.

## Device (aka Node)

Q: Where do I purchase the device hardware?
* Each [supported device](https://meshtastic.org/docs/hardware/tbeam-hardware) has a "Purchase Link".

Q: I have my hardware. How do I install the firmware and any required drivers?
* See: https://meshtastic.org/docs/getting-started/flashing-esp32

Q: How do I update the firmware to the latest version?
* If the device is running Meshtastic firmware, you might be able to update over-the-air like via the Android app.

Q: My device has gone to sleep. Are received messages lost?
* The LoRa radio on the node is still active and will wake up the CPU when the device is sleeping. If your phone is in range, the node will relay any messages your phone may have missed. If you're in range and your device is active, messages have not been lost.

Q: My device has gone to sleep and I can't send any messages.
* Once the node wakes up from sleep, your phone will relay any delayed messages through your node and to the mesh network. Give it a few minutes and it'll do the right thing.
