Yo Gater and Digital! Just curious, why have the back cover as a separate piece? I can see if it was difficult to get the battery in from the front but it may fit. If you have already tried this, please let me know. If not, I am going to merge the back plate and the main body and print them as one.

    That is a great question!

    I’ll look to see if it will fit that way.

    I still prefer to use hot melt glue or the zip tie method, but let me remix the model and see how it comes out.

    Good Suggestions, Thanks Smag!

      Instead of hot glue, for little project boxes I used that clear “All Surface” glue that you get at the craft shops. It holds very well, as in will not fall apart when knocking about. It also pries apart easily without scuffing up anything.

Just a couple of data points here in case anyone else runs into this issue.

Prior to the last video coming out I downloaded the latest stable firmware (2.1.19 IIRC) from the Meshtastic site and installed the Android app via F-Droid, as recommended by Meshtastic.

I could NOT get the device to pair with the phone. Did not pop up the code on the device screen and immediately came back with “pairing failed” in a fraction of a second on the phone.

I uninstalled the Meshtastic Android app and re-installed from Play Store as in the video, then went back and got the exact firmware version (2.1.15) that Gater showed in the video.

I don’t know if it was the firmware or the app, but it behaved as expected with the pairing code and paired just fine with the Play Store version of Meshtastic on the phone and the 2.1.15 firmware.
