Bluetooth Internal TPMS Sensors

[doctorb]

Hi y'all !
I was wondering whether anyone has experimented with internal TPMS (and TTMS) sensors that are typically connected to valve stems.
Most available use a specific radio frequency, which a smart phone cannot receive, but some use BT 4.0 at 2.4 GHz and typically link to a phone app.
Here is an example:

Is it safe to assume, that HLT should be able to read their signals?

Hi all,

I recently bought such a set of internal VC601 Bluetooth sensors like posted by doctorb.

Originally, the supplier provides an app. To pair and properly assign the 4 sensors to the correct position in this app, you have to put the app into a scanning mode and inflate the tires in a given sequence.

As I'm not planning to use that app and rather want to include the sensors into HLT, I'm wondering how the pairing and assigning procedure in HLT needs to be run?

With best regards,
Michael

Hello,

LapTimer will detect VC601 sensors automatically. VC601 do not really connect but instead send a broadcast to anyone around listening. As they broadcast their status infrequently, it may take some minutes until you get all four displayed.

Make sure BT is enabled in general and BT LE is enabled in LapTimer. See Sensor List. It will issue a warning in case BT LE is disabled in Expert Settings.

For those who have tried this, do the VC601 sensors installed on the rim inside the tire (not screwed on top of the valve stem) broadcast both Bluetooth Low Energy (BLE) and the 433MHz signal so they don't trigger a TPMS fault on the car while still broadcasting to HLT? Or is it solely the BLE signal?

Thanks for the help.

Internal and external VC601 sensors work the same. They advertise infrequently and add current pressure / temperature information to that advertising packet. That's not what advertising is designed for, but saves a lot of battery.
