@aenzed so your Suunto watch connects back to the phone using this BLE connection method with uuids and byte blob reading?

aenzed

@brechtvb Yep, UUID is set in the BLE bridge app and SuuntoPlus app explicitly The docs have a very nice walkthrough of BLE device connection, although it still took me awhile to get everything working.

@aenzed do you mean the suunto manual? It also states max 2 devices, is that 2 devices per custom suunto plus app?

aenzed

@brechtvb Yes, the manual/reference sheet in the VS code simulator. I don’t think I can answer that 100% correctly, but from the reference sheet I would say that it is max 2 devices per watch and not per app as they specifically mention watch firmware.

@aenzed okay thank you for your input.

This weekend i’m starting on reading a garmin sensor, should not be too hard.

But this limit of 2 sensors is really wild. If one cycles with:

speed
cadance
power
heart rate

sensor, we are 2 times in the blue. Suunto should really up this number, with just a note/popup that power consumption will go up because of the number of connected devices. That is totally acceptable.

Suunto users understand as well that GPS can be configured less precise for less power consumption.

Someone developed it. I assumed that you are aware.

For the sailors among us…
I’m developing an app for the calculation of Velocity Made on Course (VMC).

First of all, the simulator totally ignores the nautical distance format. The watch does format it well so it’s not a big deal.

The second issue is that I don’t see any option to get the bearing and/or coordinates of a selected POI. Only the distance is available. This makes the VMC calculation very inaccurate since the distance is measured in meters only.

The preferred way would be to calculate the VMC with the speed and angle

speed * Math.cos(heading - bearing);

All of the values are known, except the bearing to the POI. Is there any way to get this information?

Here’s my little S+ app called “Constantin” that shows either pace or HR in split view:

Graph on the left and delta / current / average on the right.

Top button switches between pace and HR.

When I run I tend to have quick glimpses on my watch to see if I have a tendency to go too fast or if my HR climbs. So I have designed a view that shows me if I’m actually deviating from the average in pace or HR or not.

It’s evolving

I went for canvas instead of default chart so that I can have the latest value exactly in the center.

@Łukasz-Szmigiel Hope to see this in the Store soon—it looks incredibly useful.

@Bigb0zz thanks, I just filled in the form to become a Suunto Partner. I’ll upload it after I’m accepted.

It should be possible to just calculate the bearing yourself.
I think we are looking at the loxodrome here:
