Emulate a ANT+ speed sensor for Garmin Edge by a BLE sensor

I have a bicycle device that delivers precise speed (mp/h) data via BLE.

Is it possible to create an IQ app which feeds the Garmin Edge series with the speed data of this device, like a ANT+ speed sensor? Thus, emulation of a ANT+ speed sensor by the BLE device?

Unless the sensor is ANT as well as BLE, you need to use BLE. Unless the sensor can pair with the FW with BLE.

Misunderstanding. My idea is to create a software speed sensor, which feeds the Garmin like a ANT+ sensor or a BLE sensor with speed profile.

The head units get wheel rotations (not mph) from the wheel sensor and calculate the speed (using the circumference of the wheel stored in the head unit).

The head units can use BLE wheel sensors.

What is a head unit?

My device delivers wheel rotations, too, and also can provide the wheel circumference.

The device the sensor talks to.

There are Dozens of wheel sensors already do this. There are dozens of computers that can use these sensors. A standard already exists.

Make your device send data the same way all of them do. You can do that using ANT+ or BLE. That’s what all the manufacturers of the many existing sensors did.

The case here is: The sensor device does not support the standard profiles for a speed sensor (ANT+ or BLE), but it has a speed value ans a usable BLE API to get this value. That's why i want to process the value on the Garmin and feed it to the Garmin as speed sensor output. Is this somehow possible with CIO?

You could write a datafield that wrote whatever it is to the activity (fit) file.

You can’t get IQ to have the headunit use your data instead of what the well-established practice is.
