i have a hint for you:
flasher.meshtastic.org
#meshtastic 

 Thank you. Couldn't get it to work on Linux. Trying CLI install... 

 chromium works for me on linux - nixos.
I had to add my user to dialout group. You can do it like this:
sudo usermod -a -G dialout USER

let me know, if it helps :) 

 I just used the CLI to do it. 

 Lemme know how it goes. I would also like to dip my toes into the meshtastic verse. Just don't know where to start.  

 So far so good. I think I will habe to wait for the city to really try it 

 Welcome to the network! You’ll figure it out. Some decent YouTube content on the subject and Meshtastic website has good info too 

 Cheers 

 You definitely have to upgrade the firmware 😅

2.5.5 is working okay so far 

 Heltec v3? 

 Yeah 

 These radios look pretty cool, I have been looking into the technology recently. Would be curious on your experience with it.
