Implementations

impl BleRadio

pub fn new(bt: BT<'static>) -> Result<Self, RadioError>

Initialize BLE in scan-only mode with minimal buffer footprint.

esp-radio’s Config::default() sizes the BT-controller blob for max_connections=6 and scan_duplicate_list_count=100. On ESP32-S3 that defaults to ~36 KB of heap, which doesn’t fit alongside LVGL on cores3 (56 KB heap). Our use case is passive scanning of Victron advertisements — we never open a connection, and only a handful of distinct advertisers exist on the bus.

max_connections=1 is the minimum the controller accepts. Setting it to 1 shrinks the per-connection static state. Combined with a 10-entry duplicate-filter (the spec minimum, range 10–1000), this frees ~10 KB on ESP32-S3 and a smaller amount on ESP32.
