RE: Supervision timeout issue

It's been a while, but I wanted to close this out. In short, mea culpa:

ble_gap_scan_params_t is passed to sd_ble_gap_scan_start() to scan for advertisements:

ble_gap_scan_params_t scan_params = {
        0,                      // Active scanning not set (we don't care about scan responses at this point).
        0,                      // Selective scanning not set.
        0,                      // White-list not set.
        BLE_SCAN_INTERVAL,      // Scan interval.
        BLE_SCAN_WINDOW,        // Scan window.
        0                       // Never stop scanning unless explicitly asked to.
};

When we want to connect to a device, we call sd_ble_gap_connect() and we passed the same scan_params[] structure which still has "timeout" set to 0 (= timeout disabled).

Are you sure the connection was actually established? If it's not you will scan for the device until the scan_params timeout is reached.
