I wish I could be more helpful, but this is a bit outside our expertise. I do suggest you open a ticket at kinomap support. They seem to want to help 3rd party devices connect to their apps.

The service it uses is the FTMS (UUID 0x1826) with the following feature Indoor Bike Data (UUID 0x2AD2) to send data to the client (app).

From the moment I set the speed instance flag bits (km/h) bit 0 and Cadence instance bit 2 followed by the Data, the kinomap application should receive depending on the configured equipment.

In short, the app works as follows, you first need to choose the type of equipment to be used (bike, treadmill, etc.) and then choose the scenario options you want to train.

Before choosing the scenario, it is only possible to test the speed and cadence to see if the data is correct, however when the test is done in the chosen scenario the data does not match what was sent.

First the Km/h is at zero, the only one that corresponds is rpm, if the speed is zero then the athlete does not travel.
But by adding the power(watt) flag bit bit 6, the km/h values start to vary according to the power values.

My question, how do I make the speed (Km/h) and power values correspond to the values I'm sending?

Or does the app according to the power data automatically calculate the speed?

[quote user=""]this is the first time I use the kit with bluetooth.
The part about advertising the service and publishing I understand, what I'm still having difficulty with is modifying the FTMS service.[/quote]

I suggest you study the BLE guides at https://devzone.nordicsemi.com/guides/short-range-guides/b/bluetooth-low-energy.

[quote user=""]Another question is about the power unit of the Kinomap or zwift app, are these values automatically calculated based only on speed?[/quote]

Can you elaborate? What is 'speed' in this context?
