DBuserror (Rapsberry Pi) #3

Closed buildog closed 4 years ago

buildog commented 4 years ago

I'm trying to use it on a raspberry pi 3B, but I got an error from DBus

const {createBluetooth} = require('node-ble')

async function main () {
  const {bluetooth, destroy} = createBluetooth()
  const adapter = await bluetooth.defaultAdapter()
  const discovery =  await adapter.startDiscovery()
  console.log('discovering')
  console.log(await adapter.devices());

  const device = await adapter.waitDevice('04:EE:03:B1:47:DF')
  await device.connect()
  console.log('connected')

  const gattServer = await device.gatt()
  console.log(await gattServer.services());
}

main()
  .then(console.log)
  .catch(console.error)
