aschnetz Hi Antoine,
After checking with our R&D team, here is the correct answer:
The FSC-BP103C uses a polling-based broadcast mechanism. Power consumption depends only on the advertising interval and TX power — not on the number of advertising slots (including TLM).
So with your configuration:
1000 ms interval, -7 dBm, 1 iBeacon slot + TLM enabled
The estimated battery life is approximately 1198 days (about 3.3 years), matching your expectation.
Feel free to proceed with this setup.
