I think that's it - Full BT vs BLE. CIQ is just BLE.

Thanks, that might be it, but not certain it explains all the differences i see. Aside from finding it in the manufactures specs, which may be hard, i am now looking for a way to determine if a device is regular bluetooth vs BLE, perhaps by looking at some characteristic or info in the advertisement. I have tried IOS tools like BlueLight but not sure i can tell from that even though i think it sees both.

sorry that is 'lightblue' - but it only mentions support for BLE, and it can see the iphone/ipad fine.

Have you tried nRF Connect from nordic? I use that on Android. I see if like device type: "LE Only" and some that do legacy, etc

I have been using IOS and use nRF connect, LightBlue and TI Sensor Tag. I just loaded nRF on my android TV box which has BLE support and can see that it is substantially different than the IOS version and offers a lot more information. I have 2 other devices which i believe are BLE, the nRF/android indicates them both as 'device type: LE Only'. I can only see once of these devices from the Garmin. There must be some subtle differences between these devices and also the iPad/iPhone - as the CIQ reports many less devices. The additonal devices can be seen by any of the utilities mentioned here, but not CIQ. Guessing now there is some variation in how these devices use the BLE standard that is not working with the CIQ. Anyhow, will explore more, thanks for putting me on to the android nRF.

I'm thinking it could have to do with the version of BLE. Some devices might use an older standard or something.

There is a BLE 'services changed' service/characteristic 1801/2A05. I do not see any mention in the Garmin SDK to be notified of this.
I wonder what the garmin device will do if a connected BLE wished to indicate that services have changed.
Has anyone tried connecting to a BLE device in which the 'services changed' condition may occur?

Did you find the solution, I am facing the same problem

I have not been actively working on this recently but may return to it some time in the future. There are a few different things mentioned in this discussion, so not completely sure which item jpbusman is referring to.
