[Ovmsdev] Bluetooth struggle

26 Mar 2020

      Dear all

I'm struggling with the activation of the bluetooth functionality with
the recent code.

The sdkconfig.bluetooth.hw31 will not compile at all.

I found three major problems here.

1. Mongoose SSL is needed
2. Support for the 8MB RAM version is needed (not included in
sdkconfig.bluetooth.hw31!)
3. CONFIG_BTDM_CONTROLLER_BR_EDR_SCO_DATA_PATH_EFF is needed for our
special esp-idf situation

By doing a simple diff I could solve 1, but overlooked Nr. 2. And that
was lethal. It brought my OVMS in a boot loop after I installed the
fresh compiled ovms3.bin. But I got here great help from Thomas
(Thanx!), who pointed to the problem and helped me out on the sdkconfig
settings.

For Nr. 3 I made a dirty workaround by adding

config BTDM_CONTROLLER_BR_EDR_SCO_DATA_PATH_EFF
    int "Should be 0, can also be 1"
    default 0
    depends on OVMS
    help
        Workaround to make bluetooth compile with our special
        esp-idf situation. 

to the KConfig.

But all efforts didn't bring a postive result. The image compiles and
boots now, but we can't activate bluetooth. We get the Error

bt: init controller failed: ESP_ERR_NO_MEM

So I would like to ask, if anybody has a working, recent, bluetooth
image and if so what does it need? Any help on this is highly welcome.

Here the diff of my bluetooth sdkconfig to the standard sdkconfig
without bluetooth:
