Hi, after pairing the V3 via ANT+ (MacOS with the Garmin USB-Dongle) in the App Trainer Road I only see "Garmin Power Meter" as it would only be one device. I just wondered if I should see two "Garmin Power Meters" with separate values etc. It would be very kind if somebody could give me a feedback regarding that issue. Many thanks in advance and best regards, Peter
For ease of use Vector has been implemented over a single BLE channel. The data from both pedals is aggregated together on the left pedal and then broadcasted over a single BLE channel. This means that when pairing with Vector over BLE you only need to pair with one device to get your data from both pedals.
From the point of view of the user today, ANT+ bike power meters will always appear as a single device on a head unit or trainer app.
The ANT+ bike power meter data profile was designed from the outset to only require a single head unit connection, with a dual-sided system implicitly required to handle the data aggregation. One of the reasons was that early on, many head units only supported a limited number of simultaneous ANT connections, and it would have imposed a significant burden for a power meter to use two connections. In today's systems, that is not so much an issue anymore but the ANT+ bike power profile has not (yet) been extended to allow dual independent connections to a head unit. Even if and when that happens, backwards compatibility will require the power meter to at least start up in a single connection mode.
