Just found this thread. As it happens I’ve been looking at visualizing rangetest.csv better too!
built a basic web app - as a web app hope to make it interactive, rather than just static view.
A few points related to what you say…
I’ve not used the range module yet, jsut been looking at the main rangetest.csv file
… it seems to have been recording since the app installed. Its definitly stored on the android device. In that time I have totally reflashed the lora device (heltec v3 in my case) with non-meshtastic firmware - still experiementing!
(docs, does say can reset it by clearing debug data - havent tried that yet!)
Its recording all messages received, as say havnt got the module enabled myself. But looking now, do see a few messages with ‘seq’ - so clearly someone else has the module enabled.
Can’t confirm anything with MQTT - not seen any messages via that yet.
