...

to connect the BT to the MyECU with a lan cable;

Cut the cable, take a look at the wires in the RJ45 plug - make note on what colour is going to what pin.

Solder wire from pin 8 to RX on the BT module.
Solder wire from pin 6 to TX on the BT module.
Solder wire from pin 1 to GND on the BT module.
Solder wire from pin 7 to VCC on the BT module.

/EDIT: the colours on my cable were

8 brown
6 orange
1 green/white
7 brown/white

/edit again, for more pics:  Grin

Excellent post 996SPS, by chance my BT module from Robosavvy turned up this morning so I immediately wired it as you say. 

I have the MyEcu on the bench at the moment (mine now has a flying lead tucked inside the case to connect 12v for testing), plugged in the RN42 module to the MyEcu and 12v to the MyEcu. I then started up my old Ipaq H3975 Pocket PC, a quick BlueTooth search found the device as RN42-589B with the service as SPP (whatever that is). EDIT: I have just found SPP is Serial Port Protocol and emulates an RS22 connection - makes sense as that is what we are trying to do!

Now I need to steal my son's phone and try the Android app.

Is there a PocketPC program available that will enable me to log a ride with the Ipaq via BlueTooth rather than using a netbook with a wired connection as I do at present?

one more thing.

I have the P8 MyECU, don't know if the pin order on the PCB is the same on the M16 MyECU?

Bobd: If you're unable to steal your sons phone, you can also try stealing your wife's android tablet.. it'll work in there too and as an added bonus, the screen is much bigger! easier to read!  Cheesy

It works with my MkIV My15M.

Grabbed the nipper's Samsung Galaxy Mini GT-S5570, the App downloaded and installed easily.

When paired with the MyEcu the phone displayed the correct battery voltage and TPS but showed both temps as -30 and the air pressure as 1000mb.  Plugging in the old Optimiser showed Oil 11',  air 8' and 1011mb.  Battery a bit flat so have not run the bike yet but assume I am connected as the TPS varies when twisting the throttle.

I now know it is neccesary to load the map from the ecu first to get it to display the full parameters.

Do you think this unit will work?  It's a Bluetooth Mate Silver RN-42 from Sparkfun.

The usual Sparkfun unit:  https://www.sparkfun.com/products/10269

Bluetooth Mate Silver RN-42:  https://www.sparkfun.com/products/10393


My favorite local full-service electrical shop sold me this, saying they were a direct replacement for the BlueSMiRF Silver unit. 

They appear the same, but this unit is "optimized" for Arduino.  It looks like the only change may be the pin outs, but I'd like a mind greater than my own to verify.

What does the board think?



I would have ordered the usual Sparkfun unit, but my store had this in stock, and was resistant to special ordering something else.

The key is that it uses the same RN-42 chip.  As long as you pay attention to the TX/RX pinouts and do them correctly, it should work just fine.

These are the important sentences that it is compatible:

The Bluetooth Mate has on-board voltage regulators, so it can be powered from any 3.3 to 6VDC power supply.

We've got level shifting all set up so the RX and TX pins on the remote unit are 3-6VDC tolerant.

Thanks for checking the suitability of the unit.

When I took computer science in school, they were still programming with punch cards.

I started my career as a programmer by writing FORTRAN II programs for this one http://www-03.ibm.com/ibm/history/exhibits/mainframe/mainframe_PP1620.html

- Punched card, paper tape and keyboard input; card, paper tape and printed output.
- Simultaneous read, compute and punch when using card input-output.
- Large-capacity core storage - up to 60,000 digits.
- High internal processing speeds. Access time - 20 microseconds.

I'm getting ready to solder the Bluetooth unit to the lan cable w RJ45 plug.  Thank you to member 996SPS for the great pictures!  Outstanding!

Any new information or tips on this that I should be aware of?

I'd like to sheath the finished assembly with heat-shrink tubing, to protect it from water, oil, etc.
Any issues with that idea?
