Hey all,

I have a heltec v3 and a raspberry pi and im looking to see how i can use my rpi to interface with the heltec device via bluetooth. Anyone have experience doing this? Id like to potentially have a web gui but also interested in using the python package to send messages based on some events ill be creating.

Hey all,
I accidentally purchased a battery for my T114 with the wrong connector. I am looking at just purchasing some JST connectors and changing the connector myself.

Is there any danger to do this while the cable is still connected to the battery?

The battery is a 803040 1000mAH 3.7V battery

Question about antennas. Is there a limit regarding size of an antenna that can be used on a device like the heltec t114?

For example, I have a old 8ft Lora Antenna that was used for the helium network at one point

I recently purchased a Heltec V3 and a Heltec T114 to start tinkering with and get more familiar with. I was also interested in seeing if I can make contact with any other nodes nearby. It turns out i'm all alone out here, at least that's what I thought.

My friends and SO have no interest in these kind of things but then an idea hit me. My daughter (who is 6) is learning to read this and is getting better with her writing as well. Shes usually my partner in crime when I get something new so I figured I'd see if this is something she'd like too.

I had an old Android phone laying around that I grabbed and spent a good 15 minutes giving her a crash course on how Meshtastic works, its components, the app, how to connect to a node and how to send messages. This was also the first instance where she has used a device to send messages to another device (my phone). The second she saw her message pop up on my phone, you could see her little mind explode with possibilities!

I had her stay in the house (with her mom) while I went outside to do some range tests and we messaged each other emojis back and forth as her little face watched me from upstairs bedroom window.

Now every morning during my morning bathroom ritual, I get these broken misspelled messages (which are totally understandable) asking me how my crap is going. This inquiry is then followed by ideas she has regarding other experiments she wants to do. Just this morning we were planning our next adventure where she was going to wait for a nice day and get her mom to bring her and her brother to the park so that she can see if we can still send messages to each other from there.

I'm so incredibly proud of her that I just had to share this with all of you. If I hadn't come across this community I wouldn't have discovered the Meshtastic project and I wouldn't have had this story to share! Thank you to all that have made this project possible.

I’ve recently come across this awesome project and have been doing a whole lot of research but there are still some questions lingering that im hoping could be cleared up by the community.

1. How safe is the encryption? Do two nodes upon initialization exchange public keys and then stored on the individual devices indefinitely? What happens if one of the nodes needs to factory reset and generate new keys. Will it let the other side know that the keys have been manipulated and require for a renegotiation to happen?
2. Is the concept of a multiple node chat/group chat possible? If not currently is it someone thing could become possible in the future?
3. voice chat; ive seen some hardware mentioning voice chat, has anyone tried this and could it be a replacement for gmrs radios with the added benefit of license free repeaters?

Thanks!
