Anyone have success with Mac OS X? Struggling here with FORDBOARD VI and Emulator

[Tim Rozmajzl]

Hi All,

Here's my setup:

• Mac OS X High Sierra - 10.13.2
  
• Python 2.7.13
• libusb 1.0.21
• Firmware: vi-emulator-firmware-FORDBOARD-ctv7.2.0.bin
• openxc version 0.13.0

Flashing emulator firmware was fine except for a sporadic errors getting into the firmware update mode.

Once all was installed (had to manually install PyBluez - failed with pip install...) I ran the following command:

$ openxc-control version --usb --format json

Got the following error output:

Can't read logs from data source -- stopping: ("USB device couldn't be read", USBError(60, 'Operation timed out'))
Can't read from data source -- stopping: ("USB device couldn't be read", USBError(60, 'Operation timed out'))

usb.core.USBError: [Errno 60] Operation timed out

So I switched to bluetooth as follows:

$ openxc-control version --bluetooth --format json --bluetooth-address <MY-HEX-ADDRESS>

Got the following error (which repeats ad infinitum):

TypeError: not all arguments converted during string formatting

Any tips would be greatly appreciated.

Thanks,

Hi Tim,

Few questions-

1. Have you connected the C5BLE with your Mac? 

2. Is firmware flashed on C5BLE VI?

3. Do you see green/blue light in the connected VI?

This error usually comes when the VI is not connected/disconnected from Mac. See the logs below:

<When the VI is disconnected>

vkanishk~$ openxc-control version

Can't read logs from data source -- stopping: ("USB device couldn't be read", USBError(60, 'Operation timed out'))

Device is running version 7.2.1-dev (emulator)

Exception in thread Thread-1 (most likely raised during interpreter shutdown):

Traceback (most recent call last):

  File "/usr/local/Cellar/python/2.7.12/Frameworks/Python.framework/Versions/2.7/lib/python2.7/threading.py", line 801, in __bootstrap_inner

  File "/Users/vkanishk/GitRepo/openxc-python/openxc/sources/base.py", line 213, in run

  File "/Users/vkanishk/GitRepo/openxc-python/openxc/formats/json.py", line 19, in parse_next_message

<When VI is connected>

vkanishk~$ openxc-control version

Device is running version 7.2.1-dev (emulator)

Thanks for your response, Kanishka.

Just to clarify, I am using the Ford Reference VI, not the C5.  But I do have the firmware installed, VI connected and blue/green light on.  BT device shows up on my Mac as connected.

FIRMWARE = vi-emulator-firmware-FORDBOARD-ctv7.2.0.bin

Hi Tim,

I tried on my Mac by connecting the Reference VI through USB using the command below and it works. When i connect the VI through USB, red light appears. When i run the version command, green light appears for a second and then i see only red light. This works even when the VI is shown as "not connected" in Bluetooth preferences

vkanishk~$ openxc-control version --form json

Can't read logs from data source -- stopping: ("USB device couldn't be read", USBError(60, 'Operation timed out'))

Device is running version 7.2.1-dev (default)

PS: Reference VI works only with Android framework. If you want to work on iOS framework/application, please use C5BLE. 

Thanks
