RaceBox micro support

[jbt_se]

Hi Harry,

Will RaceBox Micro be supported by Harry’s lap timer?

[Harry]

You need to test this yourself (and please report once you have done that). Our contact to Racebox has vanished, and we have not received replies to other mail addresses. Not sure why but it is as it is. As we do not receive support by them any more, we keep Racebox support "as is" currently.

I have done some testing and now and it won't connect to the racebox micro.
Racebox micro is not shown in the list of available GPS receivers.
Is there anything that I can provide you with so you can make it work?

Well, we can try, but it is always odd to work without proper manufacturer support...

Please install the free LightBlue app and check the Micro's peripheral name and BT LE read characteristic UUIDs. For the existing models, it is

Code: Select all

peripheralnamepattern = "RaceBox Mini (S )?[0-9]+"
readcharacteristic = sensor.btle.addcharacteristic( "6E400001-B5A3-F393-E0A9-E50E24DCCA9E", "6E400003-B5A3-F393-E0A9-E50E24DCCA9E", true)

My assumption is you can deal with this terms when using a Micro.

The simplified phrasing is "let me know the exact BT LE name of the Micro as shown in LightBlue; check if you see a service UUID 6E400001-B5A3-F393-E0A9-E50E24DCCA9E and a read characteristic 6E400003-B5A3-F393-E0A9-E50E24DCCA9E.

I assume the Micro will use these UUIDs but the name does not follow the "RaceBox Mini" pattern...

This is the data I got from lightblue.

This looks like a changed name pattern but the same API. I will add the “Micro” option to the next release that will get available in Spring. In case you want to test that front up, you need to join the HarrysLua developer program. See viewtopic.php?t=4572 for more information.

Hallo,
Ich habe immer wieder Verbindungsprobleme mit der Racebox mini und nachdem es jetzt die Micro gibt, würde es auch auf meinem Wunschzettel stehen, dort eine Integration zu haben. Ich habe die Hoffnung, dass diese stabiler in der Verbindung ist.

Die Entwicklerumgebung ist eher nix für mich, Anwendungsbenutzung ist besser für meine Nerven

Albert
PS.: Danke für die App, hatte schon viele schöne Runden damit

I've got a Racebox Micro as well, from the Kickstarter at the time.

Thanks for providing this information. Although the RaceBox guys stopped supporting us, I will try get the Micro working for the Spring release. Without access to an actual device, I will not be able to test it physically, but I can do some theoretic checking against their documentation.

[Harry]

I reimplemented the RaceBox Integration based on their API documentation and added Micro support. Actually I found several issues with the original integration, operation should be very stable with the new one. During testing, I discovered regular disconnects / timeouts in case the BT signal has been too weak. This is interesting because peer driver's RaceBox devices often create trouble because they advertise over really long distances - leading to connects to other cars. On the other hand, for stable operation, they need to be near by. Strange.

The new integration will be released as part of LapTimer's Spring release in a few weeks. Thanks for feedback once it is getting available.
