Hi, We’ve found a reproducible discrepancy between leaps\_reset sent over BLE vs over UART/USB, on LC14\_B boards (v1.1.0-a25271). Over UART (via the shell’s tlv command): sending leaps\_reset (type 0x14, no payload) reli…

We’ve discovered that a device’s absolute position (from leaps\_loc\_get’s 0x41 block) after leaps\_autopos\_start appears to be cached from its FIRST successful trigger, and does not update on subsequent triggers even aft…

Hi, One of my LC14\_B devices (addr=DECA687912909D04) has stopped advertising over BLE after a configuration test, and I can’t get it visible to a central again. Details: • Sequence: sent leaps\_cfg\_anchor\_set with led\_e…

Hi, I’m building a custom app (React Native, iOS) that connects to a LEAPS UWBS device over BLE using the documented UWBS GATT service and its Request/Response/Events characteristics. I’ve successfully implemented the T…
