However, the locally available Wind12 notebooks in the country also don't have the built-in bluetooth module. The good news is, according to the msi forum, the bluetooth module for the U100 will also work on U210. So, without hesitation (since I've already verified the other features of my unit), I opened my less-than-a-week old U230 and found out that there's also readily available connector for the bluetooth.
For this modding I chose a slim-type USB bluetooth dongle (worth Php220), so that it will be easy to disassemble and also easy to fit inside my U230.
Checking first the voltage supply for the bluetooth module.
(showing 5V across pin1/red and pin2/orange)
The electrical connection is the same as for the U100 BT mod, except for the connector's wire colors (not the typical BBROYGBVGW arrangement).
The finished 'product':
(I use the same part number of MosFET for the 'enable switch'. It's IRFR5505 P-channel MosFET.)
Putting some insulation (kapton tape)first before placing inside the unit:
Finally, SCM already detects the new hardware by pressing Fn+F9.
The bluetooth LED indicator is now also working.
And that's the do-it-yourself bluetooth module for MSI U230, costing only less than 300 pesos... =)
Hopefully I could also mod a usb hsdpa modem to fit inside the vacant mini-pcie slot of my U230.
