Yes, i will email a log over then later today.

Thanks for the help.

22

Making some progress, thanks Jani for pointing me in the right direction.

23

Nice! How are you getting the canbus info to realdash?

24

Modified version of xml file.

Data is arriving, can be observed in can monitor (0x777e frame), although i need to check accuracy, i set all tyres to 34psi, but figures were not reflecting that immediately.

25

Thanks, actually meant how is it wired? using usb to can adapter?

26

Yes, i put the can wires from TPMS reciever into the seed adapter along with the can hi lo from my ECU, data is picked up ok.

27

Went for a drive and the readings settled to what i was expecting, so i think they perhaps only transmit once in motion.

28

The updated XML for Tiremagic TPMS will be included in next release of RealDash.

29

Great, itā€™s a reasonable cost option to get TPMS data into RD.

30

Is there anything in the included RD XML that handles the learning and such settings?

31

No, you need to do all configuration with their own software.

32

Next release of RealDash will have support for Daisata TPMS addon. One more affordable option.

33

I donā€™t think tiremagic has a software for that.

34

How are you supposed to configure then?

35

Looks like through canbus. This document Dropbox - TPMS_Tiremagic_Can_Bus - Simplify your life
show that ID 0x77c is sent from an instrument cluster or other TPMS display end to put the receiver in learning mode, then the TPMS receiver sends data back on ID 0x77d

Do we have any more info in the dasaita tpms system? Iā€™ve seen itā€™s now on the list of connections in RealDash but it gives the option to connect as wifi or Bluetooth. I canā€™t find any info online about how the System works? Is it exclusive to Dasaita head units? Will it plug into any android machine? It looks from pictures that it has a wired connection which doesnā€™t seem to tie in with Bluetooth or wifi connection?
Also RealDash list it as ā€œexternalā€. Does this mean we can only use the valve cap style system and not the complete valve sensors that are available?

I assume someone has used this system and thatā€™s why there is an option in RealDash? Can we get some guidance/instructions on how we implement this tpms system? Is it possible that another generic Bluetooth tpms system would work using the RealDash dasaita connection preset?

I was all set to purchase the tiremagic system until I saw the dasaita connection pop up in the app update!

We have tested it with these simple USB adapters from Amazon. the control unit takes power from USB too. Other connection options are there if somebody wants to use a different adapter.

It is unlikely that Daisata protocol would work with any other TPMS system.

Hi
What baud rate are you using for Dasaita USB serial?

Iā€™ve just get latest from dasaita.
I canā€™t connect it.

Dasaita. Not Daisata.

Thanks for pointing that out. Will fix. Baud rate is 38400.
