Hi all, jumping onto this topic quite late, but this is something that excites me. I've also been doing a lot of research, and busy working on 2 different prototype devices specifically for tracking my bicycles. Looked at 1 year battery life minimum, and also anti-jamming functionality. We are busy building an Android application as well. I will eventually share more details, but for now its more of a personal project ???? I moved to CPT this year, and have been scared shitless that I might get hijacked. And so the journey started! GSM devices can get jammed, and LoRaWAN devices lose coverage when moving away from the base stations. We also have the issue of bikes getting across the border to neighboring countries. Then both options above are useless.
