E-Ink Screen Broke

After about a week and a half I noticed that my screen hasn’t updated. I hooked it up to my laptop and pressed the screen reset button on the device and the code said the device updated. Confused, I opened up the back of the device and noticed the ribbon clamp broke off from the glue/tape from the battery that held it in place. The device works as intended, it’s a shame that the screen became useless because the battery was stuck to the clamp instead of the back of the device

good except stock antenna

stock antenna is garbage, tubed for 1.2ghz not 915mhz

Good service and the device works

I don't remember if I had to pay extra for the Meshtasic firmware, but it had to be updated before i could use it anyway, so it was of no benefit unless it were free. Anyway, no big deal there and the device works well even though I am in a sparse area as far as nodes are concerned. My advice for setup is to set the region and keep everything else at defaults until you can make contact with another node. What screwed me up was the 4 character default key. I thought it needed to be removed or set to 'empty' and that prevented me from making connections for a few days. All good now. Stay default unless you want to keep your own network separate.

I am having trouble with the settings.

I put up a solar node about 500’ feet from the house. The solar node, up about 30 to 35’, has good coverage. I cannot communicate the the solar node with the t-echo. The unit appears to be well made, but I have not been able to effectively use it.
