I once price the Bluetooth Module in smartbox
If yours is a copy fake unit then there common to fail as its not made at Laynch factory

NZBRAKELATHES is right.the problem must be from diagun main unit bluetooth module.the best solution would be changing the module from main unit.

Reset BT module -in setting tap <-->.

Change 2 SP3232 (MAX3232)-first in motherboard =U19 ,second in BT module.

Cool!
But how was it done? I couldn't make it out how it's done?
Just reconnect via PDA? Or thru the wires of ic chip??

Hi Sergei, I've gone through the Diagun there is 5V present to the MAX3232 v+ pin, and the Module gets a stable led after performing reset, but smartBox won't connect.

Should I replace both MAX3232 chips?
Which one (for example U19) is it in the module?
Also, I see yours has two wires running from the chip, what is that for?
