ESP32 BLE NRF.setAdvertising() -> FIXME

Hi everyone! Can anyone tell what I'm doing wrong?
Code below returns:
>FIXME WARNING: check error not implemented yet:0
and sometimes:
WARNING: update connetion params status = 0, min_int = 0, max_int = 0,conn_int = 6,latency = 0, timeout = 500

setInterval(function() {
  NRF.setAdvertising({
    0x1809 : [95]
  });
}, 3000);

Firmware espruino_2v00_esp32 and espruino_2v00.90_esp32
