Toybox.BluetoothLowEnergy.Status == 10. What is this?

Hello!

Sometimes I get Toybox.BluetoothLowEnergy.Status == 10 in 'onCharacteristicWrite' callback is a Ble.BleDelegate implementation

function onCharacteristicWrite(characteristic as Ble.Characteristic, status as Ble.Status) as Void {
  System.println("onCharacteristicWrite. Status " + status.toString());
  ....
}

Meanwhile I dont see any STATUS_xxx == 10 in docs "">developer.garmin.com/.../BluetoothLowEnergy.html

So the question, what does this code mean and why it can happen?

Thanks!

Not sure of the meaning, but a couple things to look at:

-how many bytes are you trying to write? There is a small limit

-are you using WRITE_TYPE_WITH_RESPONSE or WRITE_TYPE_DEFAULT

Hi, Jim.

I'm pretty sure the length is Ok. It's always 10 bytes or less.

I Use WRITE_TYPE_DEFAULT, but let me check the first as well.

The interesting thing: it happens randomly. It can take a while to get this error. But sometimes it happens in 5 seconds after device pairing

Are you also doing reads? Are you using a queue for reads/writes? When you do a read, you want that to complete before you do a write, for example.

With a queue you can also handle things like a timeout.

No. I dont read. And yes, I use a queue for any read/write requests.

Are you sure you're staying within range while you are testing? Based on the Garmin device as well as the BLE device, the range can be much shorter than you expect. Keep the devices within say 3-5 feet of each other.

I keep the device as close as possible. It doesn't help

And looks like WRITE_TYPE_WITH_RESPONSE doesn't help

What are you trying to connect too? Could it be you're trying to write something that device doesn't allow?

0 Aleks over 4 years ago in reply to jim_m_58

It's a device I was asked to write a DataField for.

And about the second I'll ask the device developer. But anyway it's interesting to know what does 10 as the Status mean.

See if you can access any logs on the device, The device developer can tprobably ell you what's happening.
