Characteristiic throwing error org.bluez.Error.InProgress

[RobsonRojas]

I have tested the readValue to a readable characteristic and it worked fine:

  const characteristic1 = await service1.getCharacteristic(TEST_CHARACTERISTIC_WRITE)
  const buffer = await characteristic1.readValue()
  console.log('read', buffer, buffer.toString())

But, when I try to execute writeValue in an writable characteristic with the following code, it is throwing the exception:

  const characteristic2 = await service1.getCharacteristic(TEST_CHARACTERISTIC_WRITE)

  await characteristic2.writeValue(Buffer.from('s'))

The error:

Could someone help me to solve this? Any sugestion or idea?
