The M2 is just a LoRa Gateway The T1000E is a Meshtastic Node device does what it says it does… it is just like stringing two cans between neighbors… you can talk all you want but no one is listening… I am boxing up 2 right now from my haul to send to my cousin and his son and grandson so they can play with it in the mountains of north carolina… as far as i can tell it works completely as discribed… I will try to answer any more specific questions you may have… I heard yesterday it will be open sourced come next year. I think it would be a great hiking communicator… odds are the battery would be dead if you ever needed it …with the exception of the fact you need a smart phone and app to communicate with the device… but theoredically it would work in 0 cell service situations…
Surprisingly i took it to a college town in PA and was getting pings off of devices all over the place… but no one was talking… kinda like a text based CB radio… you can have open broadcast of messages or person to person on “channels” i dont know what they use it for either… probably ordering pizza if you catch my meaning…
I am going to ride by the big city and see if i get any pings today… i will report back… the only communication i ever recieved was from an airplane flying from canada to brazil… apparently they have a LoRa Meshtastic device on the plane and it was broadcasting ping messages down to earth below … my unit detected the device and a little googling showed the route going directly over my house +/- that was kinda neat…
