Your into series on LoRa has done a great job of meeting me where I am. I park my car ~1000ft from home, and LoRa looks like a good way get real time telemetry on the car alarm.

Thanks for this video. I plan on making a large node/repeater for the top of the nearest mountain. Im trying to get more people on this system for emergency communications in case the grid goes down. I figure this is the best way to stay in the loop about what’s going on without needing phone service

I have 2 Lora V2 devices and just got 7 miles. I'm in a relatively rural area in the Midwest with few hills. Buildings do a really good job at blocking 915Mhz.

Josh, this is amazing tech! I can't wait to dive into this stuff and make up some weatherproof boxes. Thanks for giving me yet another hobby! At least this one isn't as expensive hahaha!

Heck yeah, dude. Just in time! XD thank you!!

Fantastic topic!♡♡♡ thank you :)

I would encourage folks to try this stuff out and the meshtastic team is pretty darn cool, but know that this not at all ready for prime time. I am a techie with some serious professional experience in related fields, but I feel like I have falling down a rabbit hole trying to get this set up and ready for my community. Update: The things go to sleep and wake up randomly, I am seeing so many issues and feeling overwhelmed with just how far from complete this project is. It is all being created in folks free time, so I get it, but just don't prop these things up before they are ready, cause this is not at all ready! :(

Just got 3 new T-beam units from Amazon for the lower price. Working with iOS and all the issues are pretty much fixed. GPS not good indoors but good outdoors. My unit only went off when it was out of Bluetooth range. Intend to have one on the home wifi and one each on the iPhones. Attempting to get some momentum going with others in the area.

Would be interesting to see WSPR / FT8 style protocol to extend LoRa’s range.

Oh the intro was great.

This is a great video, thank you for posting! Have you tried the SX1262 chip? In python you can enable an additional mode to get some more TX power. I believe its a couple of dbs but meshtastic has said it makes a nice difference

That need help with dmr sign made me chuckle

Thanks!

if you had a repeater location that had a wide view of the area. Even thick tree leaves can kill a 900MHz range signal. Pine needles really mess with wi-fi range signals.

"nodes" and "channels" should be displayed on the screen to show exactly which screen we are on. It's a GUI designed by techies. Could be much better

commenting on tablets, I got one of the new Fire HD 10 tablets on the Black Friday Cyber Monday deals, and it apparently doesn't do BLE, or it's not a default settings. It was the first device I tried MeshTastic with and it didn't see my MeshTastic devices. My Moto X4 saw them just fine.

The little checkbox at bottom of setting screen. ... Says send usage data something something.... Has to be checked to use map ... So unchecked it and no gps or map

What happened?

Thank you for this great primer on LoRa & Mashtastic!! Plan to get 1st device(s) soon but with primary objective, reaching friends/relatives up to 50 miles away in a grid/cell network down scenario. If I understand the Meshtastic mesh network operations correctly, in order to get messages far away/beyond line of site, I'll need to use the default Meshtastic channel, send a message out to everyone, & hope there's enough nodes between me & my intended recipient miles away. Is this correct? If so, sounds like long distance communication is not doable without a lot of people using LoRa/Meshstastic & having the mesh network with multiple nodes, pre-existing. Thoughts?? Thanks!!

I’ve noticed with my units as well that the Bluetooth pairing window (your opportunity to enter the code before it times out) is laughably short. Makes it a real PITA.

hy master, i have 2 module of lora mesh after i seen your video. i need a repeater for a 915 mhz but i don t found a link to buy one. can you help me please or make a video for a lot of people like me , where the range is an issue. thanks for all , and take care.

Question1: Is there someone who has already done an amped up project for a dedicated relay to help for emergency communication. IE portable base station in the middle of no where hiking hunting earthquake response and direction for links in replicating the project. I think you mentioned max wattage 1watt. Why not 5 Watt? Question2: Is there a project out there that will relay other people traffic so if there are other hops in the middle of your private network but use someone else's project as a repeater? I would like to make such repeater.

I believe the FCC restricts the limit to 2w in the US on those frequencies. That is why you don't need a licence for them.

Do you have a link for a good 3d printed case like the one you used? Its pretty important.

Now you broadcast to all node’s connect to the channel but it’s there a wat to chat one to one so send private messege to one person only that is on the same channel?

just verifying does the t-beam have over charge/undercharge protection ?

Does anyone have a link to the short extension cable for the antenna, having a hard time trying to locate one?

I have a dumb question - sorry. If I have a network setup, and two devices. I can see that the devices can chat, do GPS (kit allowing) - does this network allow a level of sharing between the devices across apps and tools, or is it limited to the meshtastic app only? If I start FTP, Can I send or recieve across a LORA network (simply?), or we really are limited to using the limited app?

How far can that I2C screen be away from the T-Beam? Thinking of putting this on my roof and run a ribbon cable to my office.

Can it be used to control a drone to extend range?

Should 433 mHz be explored as it sits within the amateur band?

youmenationed the word node alot, i only have 1 device no extra nodes, can i still use this to talk to locals?

It works with phones and tablets via the app. Laptops, you use the wifi connection and terminal control. I just printed the case. I don’t sell them.

what 3d printed case design are you using?

Can t beams only run one channel at a time or can they bounce between channels?

Hi there! Does anyone know the FCC ID for T-BEAM? I need it for a procedure in my government.

Has anyone else had a hard time getting an 18650 battery to fit in their T-Beam? I resorted to buying a "flat top" 18650. Fits perfectly. Just a heads up.

A question came up in the chat about the RF output power of the T-Beam. 20dBm translates to about 100mW. The EIRP limit for ISM in that freq space is 4W (1W RF limit), and some experimenters are looking at amplifiers for the T-Beam (and similar devices) to bring that up to full power.

@sithticklefingers7255

The safest answer is unfortunately no. I’m not even sure where you’d start with programming those things honestly, because Motorola software costs a fortune and is incredibly hard to purchase if you aren’t working for a government agency. Additionally, these are unlikely to fall under any exemption from licensing due to their frequency range, power output, and their lack of narrowband capability. I don’t think there is any way to legally operate these radios, sadly. Emboldened bureaucracy is a terrible thing to behold. Do what you will (I imagine you’ve likely played with them already anyway) but understand that you’re handing a government agency and prosecutors rope they’ll use to hang you. I’m not saying that’s right or fair mind you, but that’s the law as it stands. The bottom line there is that if you don’t flagrantly interfere with legitimate wireless services you are unlikely to get any attention, but if you end up getting caught the consequences can be steep. You’re free to take your own risks and accept responsibility.
