Its been interesting range testing for the last year with these with family. Hopefully more devs and users join with the recent videos from hams.
@Number4lead Рік тому
How did it go? I was planning to set one up on a building that overlooks a valley where most my family live. Maybe use a high gain antenna pointing north where everybody lives, and an amp of needed.
@vibys1 Рік тому
@@Number4lead if you have a decent location like that, where everyone has line of sight, setting up a device in router mode could work well(probably wouldn't need an amp either). My urban testing has been, as expect, patchy. Although i get surprised some times when a signal does find its way through somehow.

I have been following this project for several months now. Was just waiting on some new features from Meshtastic for more capabilities with messaging direct users or other groups instead of just one group where everyone can see the message. Just picked up some hardware. My goal is to cover my neighborhood with a 5 mile radius. I have a few friends that will let me install on their houses. Each one will have a 5000mah battery with 10w solar panel to charge it. Its an interesting prepper project. Of course standard radios would work fine but this has other pros.

I’m pretty sure I read they had released an alpha for direct messages, or at least they were soon to.

Using different hardware it can be. They have preprogrammed hardware on the project website. Also, the TTGO PAX (or TTGO LORA32 v2) is a simpler hardware model with no GPS. As you use the phone anyway, the Meshtastic App connects via bluetooth and provides its GPS to the meshtastic protocol for positioning. Upload firmware -> connect via bluetooth -> Use phone app to configure device. Either power it via the phone OTG, a battery pack to its microUSB or a slim LiPo battery directly with the provided cable.

On the site of the HW board they mention 20 dBm output power (100 mW). However, in Europe the max allowed power in 433 MHz is 10 mW, and in 868 MHz is 25 mW. I wonder if the board uses the max power in all frequencies (100 mW), or different per frequency band, or it is user configured...

So anything sent over the network is readable by everyone, and I have to monitor every message to see the messages intended for me? Can the senders be identified and filtered?

Interesting technology, and it's cool, but I wonder how to use effectively if you can't use call signs, etc. Thanks.
@jmcasler1512 2 роки тому
User names work now. Secondary channels and direct messaging is supported on the device, the clients (android/iOS/web) are catching up.
@MichaelBransonCoach 2 роки тому
All communication is AES encrypted with a shared key (the channel). There are ~6 default channels configured. To create a unique channel, go to the channels settings and click the 'generate' random button. Use the resultant QR code to configure all the other phone apps. You will only see messages encrypted for that channel. You can rename nodes to the users name if preferred.

Yes, they can work together, although the iOS version is slightly behind the Android version in terms of features etc. but it appears to be very actively in development
@MichaelBransonCoach 2 роки тому
Channels are shared via QR codes. Have one phone generate the unique channel code and have other phones scan the code to configure their primary channel. (Phones can only use a single channel for now)

Technically no, as long as you have the firmware installed and configured, you just connect to the device using Bluetooth and use the app on the phone/tablet. If you want to use the web server feature, then yes, you need to be connected to your WiFi. All stated in the video.
@christophersmith1155 2 роки тому
thx
@MichaelBransonCoach 2 роки тому
No internet required. The units can connect to phone via bluetooth or operate as a wifi access point (that goes nowhere) which you then connect to with your phone. I think the android app supports serial OTG so you can cable them together. No internet means you will miss out on the GPS map feature though.
