    some little improvement.

    v2018-10-21_1
    News
    - Bootloader: If Bootloader is active then pairing is automatically accepted even if accepted by “Green button” is required in standard operation.
    Fixed
    - Modem: Some re-work. Fixed “Connecting…” message on Wavecom modems.
    - Bluetooth: From time to time the message "Synch..." was too long and contacts were not read out.

    Hi Marek,
    This last update failed. Now the BT module says "please wait" forever. and the MD option on HU is gone.
    What to do now"

    The update was done with a laptop and windows 10.
    Locking the car and wait for 5 minutes, then unlock, did not solve the problem.

    if transfer failed then the module boots into bootloader. put the key into position "I" or "II" wait 10 seconds. if
    PHM
    LED not shining then turn on the
    PHM
    . after that send the firmware again. if transfer is ok then it should reboot into standard mode.

    - Modem: After pairing is accepted then it is not possible to dial a number from the

    .

    i am an idiot. for those who have a revision "F" (mentioned on bottom right corner) then they really have an sound issue (missing bass). the solution is to remove R130 and R131. you can put 100k resistor (0603) instead or keep it unpopulated.

    this is new feature (not in previous versions) but due to CTRL-C CTRL-V error the value is too low (1.5k).

    i am really sorry and i am apologize everyone who have this issue.

    R130 & R131 are shown on this forum.

    I got the revC, works perfect.

    What is the "upgrades" between C and F ?
    I see that the revF does not support external bluetooth antenna?

    antenna is not affect the revision. i have used modules with external antenna because module + antenna was from some reason much cheaper than module with integrated antenna. and now the situation has changed and module with intergated antenna is much cheaper. onestly i prefer external antenna but with internal it is also easier to install.

    untill revision D the bluetooth module has parts from both sides because it was mostly assembled manually directly by me (and B-D were just cosmetic updates). revision E was the first revision with all parts on the top side (schematic without change) due to cheaper automatic assembly. and the revision F has these new resistors. these resistors just eliminate the noise if bluetooth modem has output in high impedance (it can appears if nothing is connected but radio is selected to bluetooth module). but due to mistake (too low value) it eliminate also basses.
