log tyre pressure/temp in Racechrono ?

RS8

Now there are different tire pressure gauges for Android, it would be ideal if Race Chrono could pair with them and display tire temperature / pressure in the race chrono and even log.

Here is two of them:

I can certainly see the use for these, but is there public APIs available for any of these?

It is funny, I was just looking into something like this.....I said, I wonder if anyone here had anything working yet?....and there is already a thread....

Does anyone know what kind of data these put out?

From reading the fobo web page, it seems they need to be "registered" in their app or something. But I wonder if they are using some kind of special protocol, or are they just streaming serial data?

For 100 bucks, it is a little over my threshold for getting one for fun to mess around with....

I think I should just ask for the hardware and the API

I just exchanged a few emails with Fobo.....at the very least I don't think that it will work for me....as they require Bluetooth 4.0, which my DroidX does not support....:(...I don't think?....Unless the OS changes that (could fix that with a new phone...)?

Long story short, they didn't seem to keen on sharing....but maybe you might have better luck since you are RaceChrono....and I am just a loony toon..:)

Has there been any progress on this? except that prices are lower... Bluetooth/BLE kit with 4 sensors: 33 USD incl shipping -- https://www.aliexpress.com/item/4-Pieces-Sensors-TPMS-Bluetooth-4-0-Car-Inner-Outer-TPMS-Tire-Pressure-Monitoring-BLE-TPMS/32842736828.html

Google shows that others have reverse engineered the communication of similar devices:

I ordered the TP630 set (mainly because of the smaller size of the outer sensors) mentioned here https://raspberrypi.stackexchange.com/questions/76959/how-to-decode-tpms-sensor-data-through-rpi3-bluetooth

I'll let you know after I get the set. Reverse engineering them shouldn't be much work.

Reviving an old thread - so info stays in one place.

Any updates on BT TPMS support? Sensors are now easily sub $100 and would be a great addition to RC.
