Flash the T-Echo with the web flasher. There's a "put in DFU mode" button that doesn't work: it turns into a checkmark, but then the drive doesn't show up. I had to manually hit the reset button twice. Then I hit the "flash" button but it flashed directly in the browser, while I was expecting to download the image and move it to the drive.
Before flashing, I backed up the meshtastic configuration with:
~/Documents/backups/meshtastic$ meshtastic --export-config > acho.yaml
Tried the open app which made me go through Obtainium which was my first successful round-trip through that particular app store.
Bluetooth pairing didn't work at first, the PIN dialog didn't show up.. worked after a couple of retries.
Once started, I did not see anything. There's a nice "privacy mode" in the settings, which are generally more intuitive than Meshtastic.
Then i tried Liam Cottle's proprietary app that is suggested in the apps list. Its "radio presets" is more visible than in the open app, so I was able to set it
The (proprietary) app has a couple of nice features:
- real time noise floor graph
- awesome "line of sight" built-in app to show elevation profiles
between two points on the map

- also awesome "antenna coverage" which does essentially the equivalent of a "site planner" but right there in the app
Everything else is relatively similar with the open app, at first glance.
